Chapter 4 Tool Nose Radius Compensation
207
Ⅰ
Programming
When No.6000 Bit5 (SBM) is set to 1, the macro statement can stop in single block and is taken
as the non-movement block in the tool nose radius compensation at the moment, which causes
the abnormal path. It is suggested that No.6000 Bit5 (SBM) is set to 0 when the system uses the
macro statement in the tool nose radius compensation mode in the course of normal machining.

z Subprogram call and macro statement call in G code
In tool nose radius compensation mode, when the system specifies the code for calling the
subprogram, it can execute the normal compensation, the compensation method of calling
program is transferred to the subprogram which is to execute the corresponding compensation.
When the system specifies G code in the radius compensation mode in the subprogram, G code
is valid, at the same time, the system cancels the radius compensation mode when the
subprogram does not end, the compensation mode is transferred to the called program which will
continuously executes the corresponding compensation.
The code for calling subprogram and subprogram return has no movement code, it is taken as
the non-movement block.

Cutting inner of the whole circle
In the tool nose radius compensation, when the system machines the inner of the whole circle
and the compensation direction is not changed, the overcut or undercut creates, at the moment,
it determines whether it alarms based on No.5008 Bit5 (CNF). When Bit5 is set to 0, No.259
alarm occurs.
