12.1.5 Active Offset Value Change Function Based on Manual Feed
Overview
When rough machining/semifinish machining is to be performed using
a single tool, you may make a fine adjustment of a tool offset value.
Moreover, at setup time, you may want to make a fine adjustment of a
workpiece origin offset once set. With this function, a travel distance
moved on an axis by manual feed is automatically added to the
workpiece coordinate system or the currently valid offset number
among the specified offset values (tool offset value/workpiece origin
offset) to make a offset value change.
Explanation
- Active offset value change mode
The active offset value change mode is set using the active offset
value change mode signal. In this mode, a travel distance moved on
an axis by manual feed is automatically added to the workpiece
coordinate system or the currently valid offset number among the
specified offset values (tool offset value/workpiece origin offset).
The types of manual feed usable to make an offset value change in this
mode are manual handle feed, incremental feed, and jog feed.
- Specifying an offset value to be changed
Specify a tool offset value/workpiece origin offset with the active
offset selection signal. A method of axis selection for tool offset
value change operation can be selected with bit 1 (ATP) of parameter
No. 5041.
In the active offset value change mode, an offset value selected is
indicated by blinking display in the state display area on the screen as
follows:
- When changing the tool offset value for an axis on which a
movement is made (parameter ATP = 0)
Offset value selected State display
Tool offset value TOFS
Workpiece origin offset WZR
- When changing the tool offset value for an axis selected by the
signal (parameter ATP = 1)
Offset value selected State display
X-axis tool offset value OFSX
Z-axis tool offset value OFSZ
Y-axis tool offset value OFSY
Workpiece origin offset WZR
NOTE
To change the tool offset value for the Y-axis, the
option for Y-axis offset is required.
