Embodiment Construction

[0041] Below, use Figure 1 to Figure 5 Embodiment 1 of the numerical control device according to the present invention will be described.

[0042] figure 1 It is a block diagram showing the composition related to the return-to-origin of the numerical control device according to Embodiment 1 of the present invention. figure 1 Among them, 11 is a gear member, which is only arranged on the main shaft side. 14 is a return-to-origin management means, 19 is a position judgment means, and its detailed operation will be described later together with the detailed operation of the return-to-origin management means 14 . Other components are the same as the existing numerical control device.

[0043] figure 2 It is a figure explaining the virtual grid of a slave axis. In Embodiment 1 of the present invention, the position judging means 19 first as follows figure 2 In that way, the grid of the slave axis (hereinafter referred to as a virtual grid) is virtually generated at a pos...

Abstract

A numerical control device for controlling mechanical equipment. The mechanical equipment is configured with two moving axes in parallel, one as a main axis and the other as a slave axis, which are driven in the same direction by separate servo motors 6 and 10. The device Carry out the homing of the main shaft and the slave shaft by means of gear pieces. The device is structurally made to have a position judging means 16 for judging whether the main shaft leads the positional relationship of the slave shaft, and according to the judgment result of the position judging means, a stopper is used to carry out the homing of the homing of the main shaft and the slave shaft Management means, so one file can be used to return to the origin of the main axis and the slave axis, and it can be reliably returned to the origin in parallel positions.

Description

technical field [0001] The invention relates to a numerical control method and device for controlling mechanical equipment. Two moving axes are arranged in parallel in the mechanical equipment, one is a main shaft, and the other is a slave shaft, each of which is driven in the same direction by a separate servo motor; The file mode is used to control the homing of the main axis and the slave axis. Background technique [0002] The numerical control device returns to the origin, so as to correctly grasp the origin on the coordinates of the mechanical equipment at the basic end. As a method of such returning to the origin, there is a method in which a limit switch (stopper) for deceleration is provided close to the origin of the moving part of the mechanical equipment. In this way, when the moving part of the mechanical equipment hits the gear, the servo motor executes the deceleration command, and after the moving part leaves the gear and first becomes the grid position, it ...
