state is set. When the cycle start switch is pressed, automatic
operation is resumed.
Explanation 5Tool retract and return after thread cutting
- Difference with regular command
1. Retract moves the tool off the workpiece between the retract-
specified axis and the thread cutting axis.
2. After the tool is retracted, a single block not containing the thread
cutting command is executed and program execution is halted.
3. When the thread cutting long axis is specified as the retract axis,
retract is not performed even by pressing the tool retract switch. After
the block not containing the thread cutting command is executed,
alarm PS0215 is generated and tool movement halts.
4. During repositioning, the tool is returned to the program execution
position in the first block not containing the thread cutting command.
- Operation procedure
1. Specify the axis along which the tool is retracted and the retract
amount by specifying "G10.6IP- -;" in the program.
2. Turn the tool retract switch ON during execution of blocks to which
plus thread cutting is programmed.
3. This sets the control to the tool retract mode, and retract is executed.
Tool retract moves the tool off the workpiece at an angle of 45° by the
retract amount between the retract axis and the thread cutting long
axis.
Retract operation differs as follows according to the relationship
between the remaining thread cutting amount and the retract amount
when the tool retract switch is turned ON.
