4.21.4 Parameter of Canned Cycle for Drilling (2 of 2)
5148
Tool retraction direction after orientation in a fine boring cycle or back
boring cycle
[Input type] Parameter input
[Data type] Byte axis
[Valid data range] -20 to 20
This parameter sets an axis and direction for tool retraction after
spindle orientation in a fine boring cycle or back boring cycle. For
each boring axis, an axis and direction for tool retraction after
orientation can be set. Set a signed axis number.
Example)
Suppose that:
When the boring axis is the X-axis, the tool retraction direction after
orientation is -Y.
When the boring axis is the Y-axis, the tool retraction direction after
orientation is +Z.
When the boring axis is the Z-axis, the tool retraction direction after
orientation is -X.
Then, set the following (assuming that the first, second, and third axes
are the X-axis, Y-axis, and Z-axis, respectively):
Set -2 in the parameter for the first axis. (The tool retraction direction
is -Y.)
Set 3 in the parameter for the second axis. (The tool retraction
direction is -Y.)
Set -1 in the parameter for the third axis. (The tool retraction direction
is -X.)
Set 0 for other axes.
5149 Override for retraction in a boring cycle (G85/G89)
[Input type] Parameter input
[Data type] Word path
[Unit of data] %
[Valid data range] 0 to 2000
This parameter sets an override value for the feedrate of retraction in a
boring cycle. The cutting feedrate override signal and the second
feedrate override signal are valid, regardless of the setting of this
parameter. The setting of this parameter is valid even when the
override cancel signal is set to 1.
When 0 is set in this parameter, the following operation is performed:
For the T series
Operation performed when 200 is set in this parameter (The retraction
feedrate is two times greater than the cutting feedrate.)
For the M series
Operation performed when 100 is set in this parameter (The retraction
feedrate is the cutting feedrate.)
