Positive tool-offset applications
The NC1 software is ideally suited to setting tools using positive tool-
offset values that represent the physical length of the tool.
Throughout this programming guide, descriptions refer to positive
tool-offset applications.
The software can also be used in applications where negative tool-
offset values are used or where all tool-offset values are entered as ±
values relative to a master tool. These applications are described
below.
Negative tool-offset applications
The offset value entered is the distance the tool tip must be moved
from the home position to reach the zero (0) position of the part
program (air-gap method), rather than the physical length of the tool.
Example
Home position, to the zero (0) position of the part
program = –1000 mm.
A master calibration tool of 150 mm is used (offset register
value = –850 mm).
The longest tool for the machine is 200 mm long.
The shortest tool for the machine is 50 mm long.
Parameters RENC[10] and RENC[11] must be set in the Setting-data
subroutine (L9760). Set them as follows:
