Description

Machining system that automatically changes with the tool

This creation provides a processing system, in particular a processing system that automatically changes with the tool.

The operation and processing methods of the existing lathes are quite different from those of the milling machine. For example, the lathe is processed by the ZX plane, the milling machine is processed by the XY plane, and the programming habit of the lathe is programmed by the axial axial diameter axis and the milling machine. These differences are programmed by the axial radius axis programming method. Therefore, when both the lathe and the milling machine are under the same operating environment, it is necessary to make some switching to be suitable for use. The current composite machining opportunity switches the environment of the lathe and the milling machine in the machining program according to the tool's style and machining process. In addition to selecting the tool, the user needs to re-select the state of the coordinate plane and switch the axial diameter in time. The state of the axis and the axial radius axis, as well as the state of the standard function code (G-CODE) and auxiliary function code (M-CODE) of the lathe and milling machine must also be switched, so the user should carefully check during programming. The state of each tool, if one state is missing, is likely to cause dimensional deviation or poor machining, and is more likely to cause a collision.

At present, the friendliness of the programming of the environment switching between the lathe and the milling machine and the correctness of the machining are to increase the M-CODE parameter to correspond to the coordinate plane of the lathe and the milling machine or the diameter axis and the axial radius of the axial direction. The axis is converted. This method reduces the error occurrence during switching. However, it is still necessary to carefully ensure that there is no problem with the command format or incorrect command settings during the check. In addition, or the G-CODE parameter that overlaps the lathe and the milling machine and has different functions, respectively, add a set of numbers in front of the G-CODE parameter to avoid confusion, and the two G73 commands of the lathe and the milling machine The function of the G-CODE parameter is very different. For example, the G73 command of the milling machine has a high-speed boring drilling cycle, while the G-CODE parameter of the lathe is horizontal (outside). The rough turning cycle, so the G73 of the two is completely different definitions, which means that the way the two actions are different is different, so the G73 command function of the lathe is changed to the G173 command, and so on. However, for the user, it is indeed possible to avoid the misuse of the G-CODE parameter, but the programming is to change the familiar command position, and still be careful when checking the program, if using computer-aided design and Manufacturing (CAD / CAM) programming, but also according to the changed position of the instruction to make relevant adjustments, if the end customer is not familiar with the construction of post-processing, it will be a small expense.

In order to solve the above requirements, the main purpose of this creation is to use the compensation table to judge whether the tool belongs to the lathe tool mode or the milling tool mode in the machining system, which can effectively improve the switching speed and accuracy of the lathe tool mode or the milling tool mode. And ensure the reliability of the system switching results.

Another purpose of this creation is to reduce the customer's original programming habits with the machining system that can be automatically replaced with the tool, thereby reducing the chance of program errors and reducing the impact on the machining results.

Another purpose of this creation is to switch between the lathe tool mode or the milling tool mode only after the work command is executed. Therefore, the user only needs to specify the tool number of the tool, and the machining system automatically switches the machining environment. Allows users to easily operate and process.

According to the above object, the present invention provides a machining system that automatically replaces with a tool, wherein the machining system includes: a parameter setting unit for setting a work command; an internal control unit for setting internal information; and a tool magazine having a lathe tool and/or a milling tool. The mode in which the lathe cutter and/or the milling cutter tool are internally configured with a plurality of cutters, and each cutter has a cutter number; and the controller according to the internal information, the work command and the tool number corresponding to each cutter Then, the comparison is performed separately to obtain the comparison result, and the controller switches the mode of the lathe tool or the milling tool according to the comparison result; and monitors the picture unit to monitor the switching state of the tool, and monitors the picture unit according to the switched lathe. The mode of the tool or milling tool changes the status of the display on the monitor screen unit.

In summary, the present invention provides a system and method for automatically changing the machining environment setting of the tool. The compensation table is used to determine whether the tool belongs to a lathe or a milling machine system, and then replaces the G-CODE parameter, the M-CODE parameter, the coordinate plane parameter, The axial diameter axis and the axial radius axis have an operating and processing environment that is convenient for the user to use and reduces the occurrence of problems, and is expected to reduce the user's original programming habits, thereby reducing the probability of program errors, and processing As a result, the number of squeaks will be much less, and the switching speed and accuracy of the lathe or milling machine system will be effectively improved, and the reliability of the system switching result will be ensured.

Advantages and features of the present invention, as well as methods for achieving the same, will be more readily understood by reference to the exemplary embodiments and the accompanying drawings. However, the present invention may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a thorough and complete and complete disclosure of the scope of the present invention.

Please refer to FIG. 1 , which is a block diagram of a processing system for automatically changing a tool according to a preferred embodiment of the present invention, wherein the processing system mainly includes a controller 1, an internal control unit 2, a parameter setting unit 3, a monitoring screen unit 4, and a knife. The library 5 is composed; the tool magazine 5 further includes the mode of the lathe tool 6 and the milling machine tool 7, wherein the lathe tool 6 has a plurality of tools 61~6m, and each tool 61~6m has a corresponding tool number of 611~ The fixed cutter number of 61m, where m is a positive integer. Similarly, multiple cutters 71~7n are arranged in the milling cutter 7, and each cutter 71~7n has a fixed cutter number corresponding to the cutter number 711~71n, where n In addition, in another preferred embodiment, in the mode of the lathe tool 6 and the milling tool 7, each tool of the lathe tool 6 is 61~6m and each tool of the milling tool 7 is 71~7m. The corresponding tool number can also be a non-fixed tool number.

The parameter setting unit 3 sets the work command for the tool number 611-16m or 711~71n corresponding to each tool 61~6m or 71~7n in the mode of the lathe tool 6 and the milling tool 7, for example, When the lathe tool 6 and the milling tool 7 in the tool magazine 5 respectively have eight tools, the tool 61 of the lathe tool 6 corresponds to a tool number of 611, the tool 62 corresponds to a tool number of 612, and the like. For the 61, 62, 63, 64, 65, 66, 67 and 68 respectively, the corresponding tool number is 611, 612, 613 to 618; the tool 71 in the milling tool 7 corresponds to the tool number 711 and so on. The tools are 71, 72, 73, 74, 75, 76, 77 and 78, respectively, and the corresponding tool numbers are 711, 712, 713 to 718. Therefore, when the user sets the work command to the turning tool 6 and the milling tool 7 by the parameter setting unit 3, for example, when the user wants to switch the turning tool 6 or the milling tool 7 in the machining system, the turning tool 6 can be The tool number of one of the tools 71 to 68 of the cutter numbers 611 to 618 or the cutters 71 to 78 of the tool number 711 to 718 in the milling tool 7 is set as a work command; in another preferred embodiment, The parameter setting unit 3 sets the work command by setting the non-fixed tool number corresponding to each of the tools 61 to 6 m or 71 to 7 n in the mode of the turning tool 6 and the milling tool 7 for each tool number, for example, When the lathe tool 6 and the milling tool 7 in the magazine 5 respectively have eight tools, the tool 61 in the lathe tool 6 corresponds to a tool number of 612, the tool 62 corresponds to a tool number of 614, and so on. The corresponding tool number is not fixed, it will be incremented according to the number of tools, and the tool 71 in the milling tool 7 corresponds to the tool number 712, the tool 72 corresponds to the tool number 715, and so on. The number is not fixed, it will be based on the number of tools. In increments, when the user sets the work command to the turning tool 6 and the milling tool 7 by the parameter setting unit 3, for example, when the user wants to switch the turning tool 6 or the milling tool 7 in the machining system, the turning machine can be used. The corresponding non-fixed tool number of the tools 61 to 68 in the tool 6 or the non-fixed tool number corresponding to the tools 71 to 78 in the milling tool 7 is set as the work command.

The internal control unit 2 of the machining system for automatically changing the tool is used to set the tool length compensation, tool radius compensation and tool radius compensation direction of each tool among the multiple tools in the mode of the lathe tool 6 and the milling tool 7. The internal information of the compensation table, wherein the internal information of the compensation table set by the parameter is set to the tool length compensation and the tool radius compensation through the internal control unit 2 when the mode of the lathe tool 6 and the milling tool 7 is set to the tool magazine 5 The tool radius compensation direction and other parameters are set; the tool length compensation is set according to the length of each tool among the multiple tools in the mode of the lathe tool 6 and the milling tool 7, because the length of each tool is different. Therefore, the setting of the tool length in the mode of the lathe tool 6 and the milling tool 7 is set separately, and the tool length of the lathe tool 6 is set according to the length of each tool on the machine. The length of each axial direction corresponding to the reference point is different, so the length is set according to each axial direction of the machine. For example, a general three-axis lathe is taken as an example, and the X-axis tool length and Y-axis knife of the knife are used. The Z-axis tool length is set separately. In addition, the tool length of the milling tool 7 is set according to the length of each tool. The value is set on each tool number according to the measurement result; the tool radius compensation is set according to The tool nose radius of each tool among the multiple tools in the mode of the lathe tool 6 and the milling tool 7 is set, because the radius of the tool tip of each tool is not the same, and there is a circle at the tip of the tool nose radius. Angle, when the surface of the end face, outer diameter, inner diameter, etc. is parallel or perpendicular to the axis, there is no error, but when chamfering, taper and arc cutting, less cutting or overcutting occurs. Therefore, the setting of the tool radius compensation is performed by setting the tool nose radius of each tool.

In the setting of the tool radius compensation direction, the tool tip is usually arc-shaped. Since the tool tip is part of the cutting force and the cutting force, the tool is usually made into a small round nose to increase the strength of the tool tip and improve. The roughness of the machined surface can be extended, and the life of the tool can be extended. However, in terms of the setting of the tool radius compensation direction, the tool is assumed to be a sharp point for the convenience of practical work, so this sharp point is called a virtual tool tip, and The setting of the tool radius compensation direction is based on the correction of the tool radius direction of the G41 command and the G42 command in the G-CODE parameter, and the G41 command is to shift the tool to the left of the starting point of the workpiece to be cut, and the G42 command. In order to offset the tool to the right of the starting point of the workpiece to be cut, the setting of the tool radius compensation direction is based on the commands of G41 and G42 to set the direction of the tool during machining. Therefore, each tool is machined during machining. The number of the imaginary tool tip of the tool number corresponding to the direction is set to 0 to 9.

In a preferred embodiment, when the tool number of a certain tool is the number of the imaginary tool tip number 0, it is in the mode of the lathe tool 6 and the milling tool 7, because the mode of the milling tool 7 is not required during processing. The tool direction is specified in particular. Therefore, when the number is set to 0, it is the mode of the milling tool 7. When the number of the tool is imaginary, the number is 9, because the number 9 and 0 are the same direction. However, in the mode of the lathe tool 6 and the milling tool 7, the mode of the lathe tool 6 is sometimes processed using a tool that does not require a specific tool direction. For example, the G-CODE parameter of the lathe mode is used when machining the tool. However, it will conflict with the G-CODE parameter of the mode of the milling machine tool 7, so the setting of the tool radius compensation direction at this time will be set to be different from the number No. 9 set in the mode of the milling machine tool 7. In this way, it can be used to determine the mode of selecting the lathe tool; and when the tool number of a certain tool is the number of the imaginary tool tip numbered from 1 to 8, in the mode of the lathe tool 6 and the milling tool 7, the lathe is used. Tool 6 The mode needs to specify the tool direction during machining. Therefore, when the number is 1~8, it is the mode of the lathe tool 6. When the number of the imaginary tool tip is any number from 1 to 8, each number The direction setting is the direction in which each tool sets the position of the cutting workpiece when it is set in the magazine 5 according to the mode of the lathe tool 6.

Referring to FIG. 1 again, the controller 1 is configured to set a work command of a tool number corresponding to a certain tool inside the mode of the lathe tool 6 and the milling tool 7 according to the parameter setting unit 3, and corresponding to a tool in the tool magazine 5. The tool number and the internal control unit 2 set the compensation table for the parameter setting of the tool length compensation, the tool radius compensation and the tool radius compensation direction of each of the plurality of tools in the mode of the lathe tool 6 and the milling tool 7. The parameters set in the internal information, and then compare the tool number, work command and internal information corresponding to a certain tool to obtain the comparison result, and the comparison method is based on the tool radius compensation direction in the internal information of the compensation table. Judging, for example, the user sets its work command in the parameter setting unit 3, and the work command is set to the tool number 611, and the tool number 611 is the tool 61 in the mode of the lathe tool 6, and the controller 1 is based on The tool number of the tool 61 is 611 and the number of the imaginary tool tip is 1 to 9 for comparison, and the comparison result is obtained. If the controller 1 is based on the comparison result, if the number of the virtual tool nose is 1, the machining system lathe The mode of the tool 6 and the milling tool 7 is further switched to the lathe tool 6 mode; or the user sets the work command in the parameter setting unit 3, and the work command is set to the tool number 711, and the tool number is 711 is the milling tool The tool 71 in the mode of 7 is controlled by the controller 1 according to the tool number of the tool 71 being 711 and the number of the imaginary tool tip being 1 to 9 to generate a comparison result, and the controller 1 is imaginary according to the comparison result. When the number of the tool tip is 0, the mode of the lathe tool 6 and the milling tool 7 in the machining system is further switched to the milling tool 7 mode; therefore, the controller 1 is a work command and a hypothesis according to the tool number corresponding to each tool. The number of the tool tips is compared to obtain the comparison result, and the controller 1 performs mode switching according to the mode of the comparison between the lathe tool 6 and the milling tool 7 in the machining system.

In another preferred embodiment, the controller 1 switches the mode switching of the lathe tool 6 and the milling tool 7 in the machining system according to the comparison result, and monitors the lathe tool 6 and the milling tool 7 through the monitoring screen unit 4. The switching state of the mode and the monitoring screen unit 4 further display the switching status on the monitoring screen unit 4 according to the mode of the turned lathe tool 6 or the milling tool 7, and the switching status displayed by the monitoring screen unit 4 includes the G-CODE. Parameters, M-CODE parameters, axial diameter axis and axial radius axis parameters and coordinate plane parameters, and the switching condition parameters are based on one of the lathe tool 6 and the milling tool 7 selected by the controller 1. The parameter is switched and the switched parameter is displayed by the monitoring screen unit 4; the G-CODE parameter and the M-CODE parameter used in the mode of the lathe tool 6 and the milling tool 7 are not the same, so the controller 1 according to the lathe tool 6 is switched with one of the modes of the milling tool 7, and the G-CODE parameter and the M-CODE parameter are respectively classified, for example: the G-CODE parameter in the mode of the lathe tool 6 The machine code G73 command is a horizontal (outer diameter) roughing cutting cycle, which is mainly used for cutting the outer diameter of the workpiece, and in the mode of the milling tool 7, the machine code G73 command in the G-CODE parameter is high speed. The drilling cycle is used to drill the workpiece, so the controller 1 classifies the G-CODE parameters used in the mode of the lathe tool 6 and the milling tool 7, and in the mode of the lathe tool 6, its M-CODE Among the parameters, the machine code M03 command, M04 command and M05 command, while the M03 command is the spindle forward rotation, the M04 command is the spindle reverse rotation and the M05 command is the spindle stop. At this time, the spindle rotated in the mode of the lathe tool 6 is clamped. The workpiece spindle, while the spindle rotated in the mode of the milling tool 7 is the tool spindle, so the spindle of the lathe tool 6 and the milling tool 7 are different, so the controller 1 will be based on the lathe tool 6 and the milling tool The M-CODE parameters used in the 7 mode are classified.

In a preferred embodiment, the parameters of the axial diameter axis and the axial radius axis used in the mode of the lathe tool 6 and the milling tool 7 are not the same, in the mode of the lathe tool 6 and the milling tool 7 The axial editing mode of the two is also different. In the mode of the lathe tool 6, the workpiece is rotated for cutting, so the processed products are mostly circular and symmetrical workpieces, so the drawing is directly labeled as the axis. The diameter axis of the direction, and for the convenience of editing, the axial diameter axis is also used for editing, and the coordinate system is also the axis axis showing the axial direction, while the pattern of the milling cutter 7 is mostly after processing. Regular shape, so whether it is in the editing or coordinate system display is the axial radius axis; so in the mode of the lathe tool 6 and the milling tool 7, and the mode of the lathe tool 6 will switch the coordinate system to The axial diameter axis shows that the X-axis and Y-axis are automatically adjusted to the axial diameter axis mode in the lathe tool 6 mode, while the Z-axis maintains the axial radius axis mode, while the milling tool 7 mode The coordinate system the full axial shaft radius mode to the axial direction.

In another preferred embodiment, the coordinate plane parameters used in the mode of the lathe tool 6 and the milling tool 7 are not the same, and the structure and processing mode of the lathe tool 6 and the milling tool 7 are different. When using the G-CODE parameter, the machine code must use the G17 command or the G18 command when using the arc command (G02/G03), polar coordinate command (G15/G16) or machining cycle command (G81~G84). To set the cutting plane, inform the controller 1 machining plane to confirm the machining depth feed axis, while in the lathe tool 6 mode, the G18 command is used, and the milling tool 7 mode is the G17 command. When the mode of the lathe tool 6 and the milling tool 7 are switched, the G-CODE parameter used for the cutting plane is also different.

Next, please refer to FIG. 2, which is a schematic flow chart of the processing method for automatically changing the tool according to another preferred embodiment of the present invention. FIG. 2 is a schematic diagram of the processing system for automatically changing the tool according to the tool of FIG. The process of the processing method. First, in step S01, the user sets a work command through the parameter setting unit 3. For example, the setting of the work command is the tool number of a certain tool in the mode of the lathe tool 6 and the milling tool 7. Following steps S02 ~ S05, the controller 1 compares the tool number of a certain tool with the number of the imaginary tool tip as number 9. If the result of the comparison is the number of the tool of the tool is number 9 Then, the process proceeds directly to step S05, and the mode of the lathe tool 6 and the milling tool 7 is switched. If the result of the comparison is that the tool number of a certain tool is not number 9, the process proceeds to step S03, and then, the controller 1 It will continue to judge whether the tool number of a certain tool and the number of the imaginary tool tip are compared with the number 1~8. If the tool number of the tool is numbered 1~8, the process proceeds directly to the step. S05, the mode of the lathe tool 6 and the milling tool 7 is switched. If the tool number of the tool is not numbered 1 to 8, the process proceeds to step S04, and the mode of the lathe tool 6 and the milling tool 7 is performed. Mode switching.

In the following steps S06 to S09, the controller 1 switches the mode of the lathe tool 6 and the milling tool 7 in the machining system according to the comparison result, and monitors the mode of the lathe tool 6 and the milling tool 7 through the monitoring screen unit 4. The switching state, and the monitoring screen unit 4, according to the mode of the switched lathe tool 6 or the milling tool 7, further displays the switching state on the monitoring screen unit 4 with its G-CODE parameter, M-CODE parameter, axial diameter axis and The parameters of the axial radius axis and the coordinate plane parameters are switched; in step S08, the controller 1 performs the G-CODE parameter, the M-CODE parameter, the axial diameter axis and the axial radius according to the switching condition. The parameters of the axis and the parameters of the coordinate plane are judged whether the switching is successful. The judgment method is to record the switching process of each parameter and finally confirm whether the switching of each parameter is successful. For example, the controller 1 compares the results according to the comparison. When the mode of the lathe tool 6 and the milling tool 7 in the machining system is switched to the mode of the lathe tool 6, the monitoring screen unit will respectively set the G-CODE parameter, the M-CODE parameter, and the axis. The parameters of the diameter axis and the axial radius axis are switched with the coordinate plane parameters, and if each parameter is switched successfully, the controller 1 will record success, and when one of the parameters fails to switch, the controller 1 will record as failure. Therefore, after all the parameter switching is completed, the controller 1 judges according to the recorded success or failure. If one of the parameter switching records fails, the controller 1 directly re-enters the step S06 to perform the tool magazine 5 again. The mode of the lathe tool 6 and the milling tool 7 are switched. If all the parameter switching records are successful, the mode of the lathe tool 6 and the milling tool 7 in the magazine 5 is switched to one of the modes, which is followed by the subsequent machining.

The above is only the preferred embodiment of the present patent, and the equivalent modifications or variations made in accordance with the spirit of the patent, the structure and function of the device according to the same concept should still be within the scope of this patent.
