•
Example of an ideal program for entry into the compensation mode:
N1 G00 X100 Z100
N2 X80
N3 G42 Z90
N4 G01 Z50
:
N4
In this program, the G42 block contains only a Z word, and points N2, N3 and N4 are all
positioned on the same straight line.
•
Either G00 or G01 must dominate the operation mode when entering into the tool nose radius
compensation mode. Otherwise, an alarm will occur.
•
When neither an X nor Z word is presented at the start up of the tool nose radius compensation
mode, or when the point where the axes are presently located is specified in the start-up block,
positioning is executed so that tool tip circle comes in contact with the segment passing through
the designated coordinates and the coordinates in the next sequence. The tool nose radius
compensation motion is activated from the following sequence.
X+
N1 G00 X100 Z100 F0.2
N2 G42
N3 X60 Z80
N4 X100 Z50
With the program above, the tool tip circle is positioned so that it comes into contact with
segments N2N3 and N3N4. That is, the blocks of commands after N3 sequence are all
executed in the tool nose radius compensation mode.
