Abstract

PURPOSE:To make a program for maintaining the cutting direction of a grindstone to the normal direction unnecessary and simplify the program by providing a normal direction control mechanism directing the rotation angle of a main shaft in response to the X-axis and Y-axis shift quantities of a work. CONSTITUTION:A numerical control unit 5 can input the command signal of a program to X, Y tables 6 moving a work 1 and is also provided with a C-axis normal direction control unit 5a, calculates the rotation angle of the X-axis in response to the X-axis, Y-axis shift quantities of the work 1, and feeds the signal to a servo motor 7 to rotate the C-axis, then corrects so that the cutting direction F of a grindstone 2 is invariably made the normal direction with respect to the machining surface of the work 1. Therefore, a program for maintaining the cutting direction of the grindstone with respect to the machining surface to the normal direction is made unnecessary, a program generation work is facilitated, thus allowing a correct grinding work.

In the process of grinding, as shown in Figure 1, the workpiece is moved in the X-axis and Y-axis directions, and the grindstone 2 is applied to grind the workpiece 1 along its contour. . In this case, the cutting direction F of the grindstone 2 is the workpiece]
It is desirable that the direction is always normal to the machined surface.

。The cutting direction F of the grindstone 2 is controlled in the normal direction by rotating the main shaft 4 to which the grindstone cutting mechanism 3 is attached (hereinafter referred to as C-axis rotation). 1
A program is needed to issue the order. Therefore, in addition to the Y-axis and Y-axis programs, 70 programs for the C-axis are required, which is complicated and extremely difficult to accurately create a program for C+tQI+.

しである。Hereinafter, the present invention will be explained with reference to the illustrated embodiment. In FIG. 3, 5 is a numerical control device 1t, which is capable of inputting program command signals to the X, Y table 6 on which the workpiece 1 is to be moved. There is. The numerical control device 5 is still equipped with a C-axis normal direction control mechanism 5a, which calculates the rotation angle of the C-axis according to the amount of movement of the workpiece 1 in the X-axis and Y-axis directions, and A signal is input to the servo motor 7 to rotate the C-axis, so that the cutting direction F of the grindstone 2 can be corrected so that it always becomes the normal direction to the machined surface of the workpiece 1.
