7.2 Chuck Barrier/Tailstock Barrier (L System)
II - 65
7.2.2 Setting the Chuck Barrier/Tailstock Barrier
(1) Using G22 and G23
(a) Three points can be input as parameters for both the chuck barrier and tailstock barrier. Set in the machine
coordinate system.
Points P1, P2 and P3 (parameter "#8301 P1" to "#8303 P3") are for the chuck barrier. Points P4, P5 and P6
(parameter "#8304 P4" to "#8306 P6") are for the tailstock barrier.
(b) The barrier region should be a symmetric shape regarding the Z axis. When the X axis coordinates of barrier
point P_ are a negative value, reverse the sign to the positive side, then convert and check.
The absolute value of each barrier point's X axis coordinates must be set as follows.
(Note that the Z axis coordinates do not have to follow this setting.)
(2) Using the PLC external signal input
Set the coordinate values for each point between "#8300 P0" to "#8314 P10".
P0 is the basic X coordinate of the chuck and tailstock barrier. Set the workpiece center coordinate in the basic
machine coordinate system as a radius value.
The coordinate value from the workpiece center (P0) is set as a radius value for the P1 to P10 X axes. The Z axis is
set as a basic machine coordinate system coordinate.
The barrier region is symmetrical in respect to P0.
The X axis coordinate of each point must be set in the following manner.
If the P8 Z axis coordinate must be less than P1 to P3, and the P10 Z axis coordinate must be more than P4 to P6.
