Abstract

PURPOSE:To make it unnecessary to execute a conversion of a unit conversion one by one by an operator, and to prevent a mistake by attaching a flag for discriminating an input dimension data, to said data, and converting the dimension data to a different dimension based on said flag. CONSTITUTION:When an operator indicates and sets a unit system from an input device 5, a flag for displaying the set unit system is attached to each dimension data by an input unit switching control part 13 and outputted to the dimension data which is inputted thereafter. In this case, in case data of a different dimension unit system must be inputted in the course of the input, its fact is noticed to the input unit switching control part 13 by depressing an inch/millimeter changeover switch. The control part 13 attached a flag for showing a fact of being a numerical value of a different unit system, to this dimension data and outputs it. In this state, when preparing execution control data, a unit conversion operating part 9 receives a conversion command from an NC program arithmetic part 7, reads out a unit conversion program from a unit conversion program memory 19, and executes a conversion of the dimension data.

(b) When creating a conventional technology program, etc., operate the changeover switch provided on the numerical control device to specify whether the dimensional data to be input is in the metric dimension system or the inch dimension system, and select either one. It was necessary to input dimension data in a unified format using the unit system.

(C) 8 Problems to be Solved by the Invention However, when inputting data such as machining dimensions, especially tool diameters, the basic data often includes inch dimensions and millimeter dimensions, Or, when inputting in inches, the actual situation is that the operator manually converts the unit of data and inputs it.

Such manual calculation input by an operator tends to cause calculation errors, and also has the disadvantage that it takes a long time to input the data.

In order to eliminate the above-mentioned drawbacks, the present invention has been developed so that when inputting dimension data, even if inch and metric dimensions are mixed, the operator can input the t&ll1i of a single position part
The purpose of this site is to provide a small collection of information on the value of the government's services.

An input unit switching control section attached to the dimensional data is provided, and a unit conversion calculation section is provided for converting the dimensional data into a different dimensional system based on the t-t flag attached to each dimensional data by the input unit switching control section. Ru.

(e) 4 Effects With the above-described configuration, the present invention stores input dimensional data with a flag indicating whether the dimensional data is in the inch system or the metric system. functions to convert into a unified dimensional system based on the flag when performing machining work, etc.

(f), Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a control block diagram showing one embodiment of a numerical control device according to the present invention, FIG. 2 is a flowchart showing an example of a unit conversion program, and FIG. 3 is a front view showing an example of an operation panel of the numerical control device. FIG. 4 is a diagram showing a display example of input dimension data.

As shown in FIG. 1, the numerical control device 1 has a main control section 2, and the main control section 2 includes a display 3, an input device 5 such as a keyboard, a machining auxiliary data file 6, and an NC program calculation section. 7, a unit conversion calculation section 9, an execution control data memory 10, an NC program memory 11, an NC program creation control section 12, an input unit switching control section 13, etc. are connected. A unit conversion program memory 19 is connected to the unit conversion calculation unit 9, and an execution control data memory 1
0 is connected to an axis control section 15 that drives and controls each control axis in the machine tool, and further connected to the axis control section 15 is a drive motor 16 that drives each of the control axes. Note that the input device 5 and the display 3 are integrated on the operation panel 17, as shown in FIG.
On 7, as part of the input device 5, a numeric keypad 5a, an inch/millimeter changeover switch 5b, an input instruction key 5C, etc. are provided.

Since the numerical control device 1 has the above configuration, when creating the cannibal program PRO, the processing dimension data MD
As A, the tool length and tool ? of the tool stored in the machining auxiliary data file 6? When inputting dimensional data as diameter tool data TDA, the input device 5 is operated to input such numerical data, but first, before inputting, the unit system of the data to be input is input to the input device 5. Set instructions via. When the operator specifies and sets the unit system from the input device 5, the input unit switching control section 13 attaches a flag to each dimension data input thereafter to display the originally set unit system, and the main control It is outputted to the machining auxiliary data file 6 or the NC program creation control section 12 via the section 2.

In this way, the operator selects the numeric keypad 5a and input instruction key 5C based on the initially set unit system.
MIJ/l=1. -r Personal information rr Dimensions data MDA or tool data TDA is input as machining dimension data MDA, and in the case of machining dimension data MDA, the NC program creation control section 12 generates a machine program P based on the data.
RO is created and stored in the NC program memory 11, and in the case of tool data TDA, the main control section 2 stores the data at a predetermined address position in the machining auxiliary data file 6. The Canadian program PRO created by the NC program creation control section 12 is attached with a flag that identifies whether the unit system set by the operator is the inch system or the metric system.

By the way, when inputting data in a different dimensional unit system while inputting dimensional data, the operator presses the inch/millimeter switch 5b while inputting data using the normal numeric keypad 5a and input instruction key 5c. and outputs a unit switching command CC to notify the input unit switching control section 13 that the input numerical value is data of a unit system different from the currently set unit system. In response to this, the input unit switching control unit 13 attaches a flag to the input dimension data of a different unit system to indicate that the value is of a unit system different from the originally set unit system, and
Processing auxiliary data file 6 or NC via main control unit 2
It is output to the program creation control section 12.

On the other hand, the dimensional data input by the operator is displayed on the display 3 in the unit system as input, as shown in FIG. That is, in the case shown in Fig. 4, tool data TDA is stored in the machining auxiliary data file 6, but if the unit system initially set by the operator is the metric unit system, input numerical values in metric units will be displayed on the display. 3, it is displayed without any special display, and only the numerical value for which the inch/mm changeover switch 5b is pressed is displayed as dimensional data in inches based on the flag attached by the input unit changeover control section 13. A display ID "in" indicating that there is a size is displayed after the display of the inch-based dimensions.

Therefore, by referring to the display 3, the operator can check whether the dimension data that he or she has currently input is handled in the correct unit system.

In this way, the dimensional data input by the operator is processed with a flag indicating whether the data is in the inch unit system or the metric unit system, and the NC program creation control unit 1221, ζ = . Based on this, a cutting program PRO is created and stored in the NG program memory 11, and the main control section 2 also stores various tool data TDA in the machining auxiliary data file 6.

Next, when using the machine program PRO or tool data TDA consisting of dimensional data in which inches and millimeters are mixed for machining control of an actual machine tool, the NC program calculation unit 7 stores it in the machining auxiliary data file 6. The cutting program PRO in the NC program memory 11 is converted into execution control data ADT that can be executed by the axis control section 15 using a known method while referring to the data related to the various tools that have been created. The NC program calculation unit 7 executes the execution control data A.
When creating the DT, if the dimensional data in the Canadian Niprogram PRO or the machining auxiliary data file 6 contains data of a dimension system different from the dimension system initially set in the Canadian Niprogram PRO, When it is determined from the flag, it immediately instructs the unit conversion calculation unit 9 to convert the dimension data.

Upon receiving this, the unit conversion calculation unit 9 reads the unit conversion program UCP from the unit conversion program memory 19 and converts the dimensional data.

That is, as shown in FIG. 2, the unit conversion program UCP determines the dimensional system that is the basis of the Canadian Niprogram PRO from the flag attached to the Canadian Niprogram PRO in step S1, and determines the dimension system that is the basis of the Canadian Niprogram PRO. If the unit system being converted is the metric system, step S2 is entered, and the data to be converted is determined to be the inch system, and the 11nch

The millimeter dimensions are converted to inches using the conversion formula of 25 and 41 nch.

□ In this way, when the execution control data ADT is created with all dimension data unified in the unit system initially set in the Canadian program PRO, the created execution control data ADT is transferred to the execution control data memory 10. The axis control unit 15 executes each drive motor 16 using control data ADT.
It should be executed by controlling the drive based on the following.

(g) 0 Effects of the Invention As explained above, according to the present invention, there is provided a dimension data input means such as the input device 5, and the input dimension data is in the inch system or the metric system. An input unit switching control section 13 is provided that attaches a flag to each dimension data to determine whether the dimension data Since a unit conversion calculation unit 9 is provided, when inputting dimensional data, the operator can perform complicated unit conversions by hand depending on whether the input dimensional data is in the inch system, metric, -)/7"F-ness, etc. Even if you do not do this, you can just input each dimension as is, so there will be no calculation errors and data input can be done in a short time.
