Format
Specify a retraction axis and distance in the following format:
Specify the amount of retraction, using G10.6.
G10.6 IP_;
IP_ : In incremental mode, retraction distance from the
position where the retract signal is turned on
In the absolute mode, retraction distance to an absolute
position
The specified amount of retraction is effective until
G10.6 is next executed. To cancel the retraction,
specify the following:
G10.6 : (as a single block containing no other commands)
Explanation
- Retraction
When the TOOL WITHDRAW switch on the machine operators panel
is turned on during automatic operation or in the automatic operation
stop or hold state, the tool is retracted the length of the programmed
retraction distance. This operation is called retraction. The position at
which retraction is completed is called the retraction position. Upon
completion of retraction, the RETRACT POSITION LED on the
machine operators panel goes on.
When the TOOL WITHDRAW switch is turned on during execution of
a block in automatic operation, execution of the block is interrupted
immediately and the tool is retracted. After retraction is completed, the
system enters the automatic operation hold state.
If the retraction distance and direction are not programmed, retraction
is not performed. In this state, the tool can be withdrawn and returned.
When the TOOL WITHDRAW switch is turned on in the automatic
operation stop or hold state, the tool is retracted, then the automatic
operation stop or hold state is entered again.
When the TOOL WITHDRAW switch is turned on, the tool withdraw
mode is set. When the tool withdraw mode is set, the TOOL BEING
WITHDRAWN LED on the machine operators panel goes on.
- Withdrawal
When the manual mode is set, the tool can be moved manually (Manual
continuous feed or manual handle feed) to replace the tool or measure a
machined workpiece. This operation is called a withdrawal. The tool
withdrawal path is automatically memorized by the CNC.
- Return
When the mode is returned to automatic operation mode and the TOOL
RETURN switch on the machine operators panel is turned off, the
CNC automatically moves the tool to the retraction position by tracing
the manually-moved tool path backwards. This operation is called a
return. Upon completion of a return to the retraction position, the
RETRACTIONS POSITION LED comes on.
