Description

Warm-up time control method integrating tool and processing conditions

The present invention relates to a warm-up time control method, and in particular to a warm-up time control method that integrates cutting tools and processing conditions.

Computer Numerical Control (CNC) machine tools are one of the most important processing tools in current machining. Compared with traditional lathes and milling machines, its advantage is that CNC machine tools can be manufactured through computer-aided manufacturing (Computer Numerical Control). -Aided Manufacturing (CAM) software converts CNC machining formulas and uses cutting tools to process parts (processed parts).

Based on the above, during the processing process, CNC machine tools often need to replace cutting tools to complete the processing of the workpiece. However, due to the thermal expansion and contraction characteristics of materials, when the first cutting tool completes processing of the workpiece, the replacement second cutting tool has not yet reached a thermal equilibrium state. Therefore, if the second cutting tool is immediately in a temperature unbalanced state, Cutting tools are used for processing, which will result in the accuracy of the workpiece being unable to meet the requirements of precision machining.

Furthermore, as the cutting process progresses, the processing temperature on the cutting tool increases by one degree. The total length of the cutting tool may extend due to the material characteristics of thermal expansion and contraction, thus causing processing errors and failing to meet precision machining requirements. Require. However, if you wait for, for example, 5 minutes to warm up the machine in order to meet the requirements of precision machining, it is often because the actual cutting time is too short. For example, the second tool used only needs 30 seconds of cutting time, but it does not work. Because you have to wait 5 minutes for the machine to warm up, you cannot meet the requirements for rapid production and mass processing. Even if the second tool used requires a longer cutting time, it still cannot avoid the problem of too long warm-up time under the conditions required for precision machining.

As mentioned above, since the processing system of the machine tool involves the thermal expansion and contraction effects of a series of parts, the coordinate position of the tip (cutting point) of the cutting tool changes in the three-dimensional space. Furthermore, the cutting tool is mounted on the tool handle, the tool handle is mounted on the spindle, the spindle is set in the spindle box, and drives the lead screw through the drive motor at the rear end to further drive the spindle to rotate. In other words, the thermal expansion and contraction effects of a series of parts formed by the cutting tool body, the lead screw, the track, the spindle, the tool handle and the cutting tool will eventually further cause the change of the coordinate position of the cutting tool tip in the three-dimensional space, thus affecting the processing efficiency. Accuracy.

In addition, in the prior art, in order to overcome the above-mentioned warm-up problem, a temperature rise model is established to compensate for the tool length. According to the basic characteristics of the material, under the known thermal expansion coefficient of the material and the current processing environment temperature, basic mathematical formulas can be used to calculate the change in the size of the machine part material when the temperature rises, and compensate for the change in length. The temperature rise model established. However, it will take a lot of time and cost to establish a temperature rise model for each change of cutting tools and input it into the processing program.

However, due to the numerous parameters of cutting processing behavior, if the user must warm up each cutting tool before processing, it will cause difficulty and inconvenience in writing processing programs. Furthermore, even if the processing method is written in this way, the processing parameters cannot be dynamically modified intelligently. Therefore, the parameters cannot be accurately and dynamically adjusted according to changes in the actual processing environment and processing tasks, thus affecting the processing accuracy. Furthermore, the current CNC machining formulas converted from the computer-aided manufacturing design of traditional cutting tool machines cannot select corresponding processing parameters according to the conditions of the cutting tool. For example, when the cutting tool is made of high carbon steel or diamond tool material, Due to the different materials, the cutting processing parameters of the two are bound to be different.

Accordingly, how to provide a precision machining method for cutting tool machines has become an urgent research topic.

In view of the above problems, the present invention discloses a warm-up time control method that integrates tools and processing conditions, including the following steps: establishing an initial tool and processing condition database based on all cutting tool data; storing the initial tool and processing condition database; Enter the initial tool and processing condition database into the processing formula of the cutting tool machine; measure and determine whether the tool tip coordinate value of the cutting tool tip position in the three-dimensional space falls within the processing error range; if the cutting tool tip position If the tool tip coordinate value of the position in the three-dimensional space falls within the processing error range, the cutting tool machine performs the processing task; if the tool tip coordinate value of the cutting tool tip position in the three-dimensional space does not fall within the processing error range, dynamic adjustment The initial warm-up time is used to correct the machining accuracy of the cutting tool to fall within the machining error range, and then the cutting tool machine proceeds with the machining task.

Based on the above, the warm-up time control method of the present invention that integrates cutting tools and processing conditions establishes an initial tool and processing condition database from the initial stage of using cutting tools, that is, for the processing tasks of the cutting tool machine, and can effectively target the cutting tools. Establish a tool processing model based on various processing characteristics and cutting conditions, so that the cutting tool machine can quickly load the tool processing model and execute the processing task. In addition, when the cutting tool machine performs processing tasks, it can dynamically correct the tool processing conditions through real-time measurement and logical judgment, so as to intelligently perform processing based on the parameters of the tool processing conditions. Accordingly, compared with the conventional technology that requires time-consuming and laborious efforts to establish a temperature rise model, the present invention can shorten the warm-up time of cutting tools through intelligent and dynamic parameter adjustment, achieve precision machining more accurately, and further improve machining efficiency. .

Please refer to FIG. 1 , which is a step flow chart of the warm-up time control method integrating tool and processing conditions according to the present invention. The warm-up time control method that integrates tools and processing conditions includes the following steps: In step S11, an initial tool and processing condition database is established based on the cutting tool data. In step S12, the initial tool and processing condition database is loaded into the processing program of the cutting tool machine. The processing program includes the required measurement tool coordinate position program, which is integrated into the main program of the configurable architecture in the form of a subprogram. . In step S13, measure and determine whether the tool tip coordinate value of the cutting tool tip position in the three-dimensional space falls within the processing error range. In step S14, if the tool tip coordinate value of the cutting tool tip position in the three-dimensional space falls within the processing error range, the cutting tool machine performs the processing task. In step S15, if the tool tip coordinate value of the cutting tool tip position in the three-dimensional space does not fall within the processing error range, the initial warm-up time is dynamically adjusted to correct the tool tip coordinate value of the tool tip position if it falls within the processing error range. Once within the range, the cutting tool machine performs the machining task.

In step S13, the step of determining whether the tool tip coordinate value falls within the processing error range includes measuring and determining whether the processing temperature of the cutting tool before executing the processing task reaches thermal equilibrium with the processing environment of the cutting tool machine. Furthermore, as mentioned in the above-mentioned prior art, due to the thermal expansion and contraction effects of various parts in the cutting tool machine, the tool tip coordinate value of the cutting tool tip position in the three-dimensional space may not fall within the machining error. Therefore, by measuring whether the tool tip coordinate value of the cutting tool tip position in the three-dimensional space falls within the processing error range, we can further determine whether the processing temperature of the current cutting tool before executing the processing task is consistent with the cutting tool machine. The processing environment has reached thermal equilibrium. In other words, when the processing temperature of the cutting tool before performing the processing task and the processing environment of the cutting tool machine have reached thermal equilibrium, the coordinate value of the cutting tool tip position in the three-dimensional space will fall within the processing error range. . When the processing temperature of the cutting tool before performing the processing task and the processing environment of the cutting tool machine do not reach thermal equilibrium, the tool tip coordinate value of the cutting tool tip position in the three-dimensional space will produce a large processing error.

Cutting tool data includes data on various related processing conditions and processing parameters of cutting tools, such as tool processing characteristics and tool cutting condition data, including processing temperature, processing material, rotation axis speed, feed rate, initial warm-up time, tool Size, tool shape, workpiece material, cutting feed, tool life, tool hardness, cutting force, cooling method, coolant flow, thermal expansion coefficient, etc. The data of these cutting tool data can be set according to manufacturer's recommended values, staff experience values, historical processing data statistical values or processing preset values. For example, when the cutting tool is made of a material with higher hardness, the cutting feed amount when cutting the material can be set smaller. The corresponding settings of the relevant numerical values are well known to those with ordinary knowledge in this technical field and will not be discussed here. Repeat. In addition, in the method of the present invention, the cutting tool data is obtained through computer networking technology and stored in the cutting tool machine.

After the various relevant data listed in the above various cutting tool data are input into the initial tool and processing condition database, the tool processing conditions of various tools can be established based on these data and stored in the storage device, including the internal memory of the cutting tool machine. body, external memory device, computer, server or cloud network connected to the cutting tool machine. The initial tool and processing condition database storage method can be connected to the cutting tool machine using wireless communication technology or wired communication technology. The initial tool and processing condition database contains various variable data fields, which are used to fill in the settings of various variable data in the cutting tool data. After completing the settings, the cutting tool machine reads and loads the tool processing conditions related to the cutting tool from the initial tool and processing condition database according to the processing task, and establishes the tool processing conditions for various tools accordingly. In fact, the tool machining conditions are loaded into the cutting tool machine through the initial tool and machining condition database, and are compiled through program compilation into a machining subprogram, which is called and used by the main machining program.

The various relevant data related to the cutting tools mentioned above directly affect the processing accuracy of the workpiece. Therefore, in one embodiment of the present invention, the tool tip coordinate value of the cutting tool in space is used as one of the considerations that affects the machining error accuracy, but this is not limited in the present invention. In addition, the tool tip coordinate value of the cutting tool tip position in the three-dimensional space is measured by a measuring device such as a tool measuring device, and the measured values are sent back to a processor for judgment. The processor includes a processor of a cutting tool machine, a processor in an external storage device, or a cloud server, and is not limited in the present invention. That is, the judgment action can be performed inside or outside the cutting tool machine. In addition, in embodiments of the present invention, in addition to measuring the tool tip coordinate value of the cutting tool tip position in the three-dimensional space, the measuring equipment can also be used to measure the damage state of the cutting tool.

Please refer to Figure 2, which is a flow chart of the present invention for measuring and judging whether the spatial tool tip coordinate value of the cutting tool falls within the processing error range. The steps for measurement and judgment are as follows. Take the spatial tool tip coordinate value of the cutting tool on the Z axis as an example. The tool tip coordinate value of the cutting tool must be processed after reaching thermal equilibrium in order to maintain high accuracy. Therefore, before processing, it is necessary to measure and determine whether the position of the cutting tool tip coordinate point falls within the processing error range. The steps of measurement and judgment are as follows: In step S21, the tool tip coordinate value of the cutting tool in the three-dimensional space is measured. In step S22, an initial warm-up time is set. In step S23, it is measured and determined whether the tool tip coordinate value of the cutting tool falls within the processing error range after each initial warm-up time. If not, in step S24, an initial warm-up time is added for warming up; if yes, in step S25, the cutting tool machine performs the processing task.

Following the above, in step S23, the tool tip coordinate value of the cutting tool is measured and judged whether it falls within the processing error range after each initial warm-up time. This means that, for example, the second initial warm-up time is performed. After the time, compared with the first initial warm-up time, the tool tip coordinate value of the cutting tool has fallen within the processing error range, which means that the processing environment of the cutting tool and the cutting tool machine has reached thermal balance, and the cutting tool machine can execute processing tasks.

In step S24, if the tool tip position does not fall within the processing error range after each initial warm-up time, it means that, for example, after the second initial warm-up time, compared with the first initial warm-up time, time, the tool tip coordinate value of the cutting tool has not yet fallen within the processing error range, which means that the processing environment of the cutting tool and the cutting tool machine has not reached thermal balance, and the cutting tool machine is not yet able to perform the processing task. Therefore, an initial warm-up must be added. It takes time to warm up, and after the warm-up, the operations from step S21 to step S23 are repeatedly performed.

Based on the above, in the embodiment of the present invention, the tool tip coordinate value position of the cutting tool measured in step S21 in the spatial coordinates further includes the X-axis tool tip coordinate value position and the Y-axis tool tip coordinate value position. In the present invention The embodiment is not limited to the spatial tool tip coordinate position of the Z axis.

In the above step S25, before the cutting tool is warmed up with the initial warm-up time, if the tool tip coordinate value of the cutting tool tip in the spatial coordinates has fallen within the processing error range, the initial warm-up time is shortened to a minimum. Improve the warm-up processing time. The reason why the cutting tool tip coordinate value falls within the machining error range before it is warmed up with the initial warm-up time is that the time interval between the cutting tool machine and the last machining task is short, so the warm-up time can be shortened.

For example, if the original initial warm-up time is 180 seconds, after the cutting tool is warmed up for 180 seconds, if the tool tip coordinate value of the cutting tool tip in the spatial coordinates has fallen within the processing error range, Then the initial warm-up time can be shortened to 120 seconds when the next processing task is executed, and the initial warm-up time can be set as the initial warm-up time when the next processing task is executed, or the user can set a decreasing warm-up time. .

Furthermore, the method of shortening the initial warm-up time includes replacing the value of the initial warm-up time with an algorithm. The algorithm involves replacing the value of the initial warm-up time with a mathematical model. For example, the warm-up time can be changed through a formula, such as the initial warm-up time is T and the initial number of warm-ups is 1. Accordingly, various algorithms can be used to dynamically modify the initial warm-up time and dynamically change the tool processing conditions to further establish the tool processing model so that it can be quickly loaded into the cutting tool machine when the cutting tool machine performs similar processing tasks. The warm-up parameters or the tool compensation setting value.

In addition, in addition to using the above algorithm to correct the initial warm-up time, a statistical average calculation method can also be used instead of modifying the initial warm-up time. For example, after 5 warm-up times, the average value is 150 seconds, then the initial warm-up time field in the initial tool and processing conditions database is replaced with the average value of 150 seconds.

In embodiments of the present invention, in addition to determining whether the spatial tool tip coordinate value of the cutting tool falls within the processing error range after executing the above-mentioned initial warm-up time, it also includes measuring and determining whether the cutting tool machine is performing the processing task. Whether the previous processing temperature has reached thermal equilibrium with the processing environment. The so-called processing environment includes the processing area inside the cutting tool machine, the workbench of the cutting tool machine, and the body of the cutting tool machine. Furthermore, since various cutting tools are set in the tool changing tool magazine before cutting, when a new cutting tool is replaced into the processing environment, the temperature of the cutting tool body has not yet reached thermal equilibrium with the processing environment. Under this condition, the machining accuracy may cause errors due to thermal expansion and contraction. For example, assuming that the overall temperature of the machining environment is 40 degrees, and the temperature of the cutting tool when it is replaced from the tool changer is 30 degrees, you must wait until the temperature of the cutting tool body reaches, for example, 38 degrees before the cutting tool can be used with the tool changer. When the processing environment reaches thermal equilibrium, high processing accuracy is maintained, that is, the cutting tool at this time is in a state of temperature equilibrium.

In addition, in terms of measurement, in addition to measuring the cutting tool tip coordinate value in spatial coordinates, the length change of the cutting tool can also be measured to determine whether the length change falls within the error range. Similarly, in measurement, the temperature difference of the cutting tool body can also be measured to determine whether the length change falls within the error range or whether the total length of the cutting tool falls within the processing error range. In the present invention, There is no limit to the method of measurement, or the judgment can be made by combining the cutting tool tip position, the cutting tool length change, and the cutting tool body temperature difference, or by combining two of the factors.

Furthermore, the judgment standard can also be based on the measured values of the coordinate points twice before and after. For example, when the second tool tip coordinate value in the spatial coordinates of the cutting tool measured for the second time is different from the first tool tip coordinate value in the spatial coordinates of the cutting tool measured for the first time, the If the subtraction value exceeds the processing error range, it means that the cutting tool machine has not yet reached a thermal equilibrium state. When the third tool tip coordinate value in the spatial coordinates of the cutting tool measured for the third time is compared with the second tool tip coordinate value of the cutting tool measured in the spatial coordinates for the second time, it falls within the processing error range. Within, it can be judged that the current cutting tool machine has reached a thermal equilibrium state. In addition, in one embodiment of the present invention, in the judgment, the cutting tool machine compares the currently measured tool tip coordinate value with the setting value stored in the initial tool and processing condition database fields. If the error between the two falls within the processing error range, the processing task will be carried out. In one embodiment of the present invention, the first tool tip coordinate value, the second tool tip coordinate value, and the third tool tip coordinate value include the Z-axis tool tip coordinate value. In another embodiment of the present invention, the first tool tip coordinate value, the second tool tip coordinate value, and the third tool tip coordinate value further include X-axis and Y-axis tool tip coordinate values.

Following the above, since the initial warm-up time can be dynamically corrected through the various algorithms mentioned above, the cutting tool machine will continuously adjust and correct the numerical value of the tool processing conditions and the tool tip coordinate value in the spatial coordinates in this way. The warm-up time is shortened and the processing accuracy is improved.

The warm-up method can be carried out according to the time and method recommended by the cutting tool data. For example, if a cutting tool machine is not cutting and is idle for a period of time after changing the tool, the heat convection or radiation generated in the processing environment, the processing area inside the machine tool and the workbench of the cutting tool machine, and the body of the cutting tool machine will The thermal balance of the entire processing environment is achieved between the heat conduction generated and the heat conduction generated by the newly replaced cutting tool body. If the tool tip coordinates measured twice before and after this time fall within the error range, it means that the warm-up process has been completed, and the processing environment status at this time is recorded in the initial tool and processing conditions database for the next step. When processing at one time, the relevant parameter settings can be quickly loaded to complete the warm-up action.

In addition, the process of measuring and judging whether the cutting tool tip coordinate value falls within the processing error range in Figure 2 above can be integrated into a processing sub-program, application program (APP) or installation program (program). The processing sub-program After being stored in the storage device or memory, the process is carried out after being called by the main processing program. The application program includes applications (APPs) of various smart devices today, and the installation program includes the installation program in the computer system. After the smart device or computer system is connected to the controller of the cutting tool machine through the communication protocol, Command the cutting tool machine to execute the application program or the installation program. It should be noted that the application program and the installation program are compiled into instructions readable by the controller through compilation. Those with ordinary knowledge in this technical field should be able to understand the specific implementation, and will not be described again here.

Furthermore, tool machining conditions are also related to the time course of the machining task. For example, when the schedule of the machining task reaches the working day on Monday morning, because the cutting tool machine has been cold for two days, at this time, the initial warm-up time of the tool machining conditions stored in the initial tool and machining condition database is A longer initial warm-up time can be automatically introduced during the working day on Monday mornings. When the time course of the processing task is shorter than the downtime after the previous processing, at this time, the initial warm-up time of the tool processing conditions stored in the initial tool and processing condition database can be automatically brought into the shorter initial warm-up time. The relevant initial warm-up time value can be set according to the manufacturer's recommended value, staff experience value, default value, or provided by the processing sub-program, application program (APP) or installation program (program).

In addition, after the cutting tool machine receives the processing task, the processor can determine the need to load the required tool processing condition parameters from the initial tool and processing condition database according to the processing formula in the processing task. For example, if the processing task includes processing with a cutting tool made of tungsten carbide, the processor will load the relevant tool processing condition parameters for the cutting tool made of tungsten carbide into the cutting tool machine, including the above-mentioned initial warm-up. According to the time and number of times, the corresponding parameters can be loaded more accurately according to the tool machining characteristics and tool cutting conditions of the cutting tool to achieve the purpose of precision machining.

Please refer to Figure 3, which is a schematic diagram of the device of the warm-up time control method integrating tool and processing conditions according to the present invention. The warm-up time control method that integrates tools and processing conditions is to establish an initial tool and processing condition database 11, store it in the storage device 12, load it from the cutting tool machine 13, and transmit it to the processor before performing the processing task. The device 14 determines whether the tool tip coordinate value of the cutting tool falls within the processing error range. It should be noted that in FIG. 3 , although the storage device 12 and the processor 14 are drawn separately from the cutting tool machine 13 , in fact, the storage device 12 and the processor 14 can also be provided inside the cutting tool machine 13 . The invention is not limited.

To sum up, the warm-up time control method of the present invention that integrates tool and processing conditions starts from the setting, storage and judgment of the warm-up time, and the use of reading and writing data in the cutting tool machine controller, through various algorithms Based on the calculation results, the warm-up model of the cutting tool machine can be effectively established according to various machining characteristics and cutting conditions, so that the cutting tool machine can quickly complete the warm-up and execute the machining task. In addition, when the cutting tool machine performs the processing task, the tool processing conditions can be dynamically corrected through real-time measurement and judgment to ensure that the entire processing of the entire system including the cutting tool machine and cutting tools (but not limited to) can be Automatically and quickly reach a processable state. Accordingly, compared with the conventional technology that requires time-consuming and laborious efforts to establish a temperature rise model or can only set a fixed time to warm up before processing, the present invention can shorten the warm-up time and reduce energy waste through intelligent and dynamic parameter adjustment. , further improving processing efficiency.
