Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the interference chiseling method of a numerically controlled (hereinafter referred to as NC and grid) lathe.

Interference Ceno 7 method of NC lathe has f/, ) on the workpiece.
It is controlled by the numerical information corresponding to the position of the tool, and
When machining a workpiece, the position information of the tool Vt4-
It can now be controlled without interfering with other Nayatsu and Ralstonok. Furthermore, regarding lathes that improve productivity, especially lathes with multiple tool mounts, there has been a problem in checking for interference between the turrets (hereinafter referred to as turrets) and the 8 movements of the turrets.

In this invention, the operator determines the interference between the turrets, inputs a signal sound to stop the turret movement, and after a while, the NC determines the interference state and then automatically restarts the turret movement to continue. It is proposed that the government implement the following measures.

FIG. 1:j is a diagram showing a schematic configuration of a lathe with multiple tool rests. In FIG. 1, a cylindrical workpiece 2 is positioned and fixed on the rotor ΦNayasoku 11'i: around the rotation axis (Z-axis), and the workpiece 2 is positioned at one end or at the tip of the tail stock 3. 186 and 7 are fixed to 3a, 4, and 5, respectively, which perform the cutting of screen 2. .When cutting the workpiece 2, the 11th turret moves to the second turret 4.5 arrows Z 10,000 [I]], and the tool 6.7KJ: Riso 2 is cut. It turns out.

This is an interference check discriminator that determines whether or not ~f'.

Next, the operation will be explained. When the first turret moves 5 times, its movement data enters the first turret movement data register 10, and when the second turret moves 5 times, the movement data is entered into the first turret movement data register 10.
The movement data is manually input to the second source, the throat movement game=-Tank Star 11. The interference check discriminator 12

This is done every time one unit of movement (hereinafter referred to as 171) of the movement of the second credit 5 is completed. 7) A first turret standby release signal 22 is a second turret standby release signal that is generated each time the first turret 4 is cocked.・This will be explained.

Next, the second turret 5 also moves, and a movement no-event is entered in the second turret movement data register 11.
The first turret 1-4 and the second turret 5 move at the same time and interfere (-so K becomes 8-). If you decide that one is better, the second evening 1... throat 5

The interference turret 7 discriminator 12 contains only the turret and the transfer U puller of the first clet 4 (ζ), 1 (~f- is "'-") so that the first turret 4 and the turret 5 of 42 do not interfere. .

When one mountain is completed and the first turret transposition 1 gator L/gister 1o becomes %oIT, the second turret standby release signal VC, the second turret standby release signal is sent. When +i22 is output, the second turret -75 moves Y and the flip flop 16 is reset (f1/).
t/c-C waiting iso signal 20 is +1'K 7. Since the C9, 7 point gate 18 is turned on ((Thus, the data of the second Klet movement register 11 is output. In this case, the movement of the first Klet 4 is completed), the interference check is determined. In the container 12 (1) the second blade 5 can move freely without causing interference (4).

Next, move the 1st turret 4 and the 20th) turret 5! 1u

A standby signal from the outside may be used for the turret.In the above embodiment, the interference chiseling between two turrets will be explained.
9. Mutual interference can be prevented 1. As explained above, this invention has a number of tool rests.
f4) Mutual interference of the scale control lathe is prevented by a standby signal, and the interference state is canceled and restarted automatically.1 This allows for highly safe and easy-to-operate numerical control. It would be effective if a lathe interference check method could be obtained.
