1.2 ACTIVE OFFSET VALUE CHANGE FUNCTION BASED ON
MANUAL FEED (FOR THE LATHE SYSTEM)
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)
