G102 X50. Z-40. R5.;
G103 X60. Z-42.5 R2.5 ;
G101 Z-60. ;
G101 X70.; ------ the last figure of the finishing figure
(Note) The example of the figure blocks is programmed in the diameter units for
X-axis. So it is necessary to set the PMC signal G296.0 to 1 for
executing this sample program.
(4) The Others
(4.1) About the tool nose radius compensation of Bar roughing cycle
During Bar roughing cycle, G40 mode is displayed in the modal G code
information. But the tool nose radius compensation is executed without
G41/42 command. By using T-offset and imaginary direction (D-value),
turning cycle system calculates the imaginary tool nose points as follows.
And the points are commanded. Therefore, on the position display, the
imaginary tool nose points are displayed.
(4.2) About the cutting start point
Cutting start point should be set as follows. In the following explanation,
CLRX/ CLRZ means clearance amount. And it should be decided by an
1. Cutting start point of Bar machining
1) Cutting start points of [OUTER]
X = [Xmax : Maximum outside coordinate of a figure] + [CLRX]
Z = [Zs : Z coordinate of figure start point] + [CLRZ]
