1. Outline
If you want to perform roughing or semi-finishing with a single tool, you may fine-adjust
the tool compensation. Moreover, you may want to fine-adjust the setting of the
workpiece origin offset that was already set up. This function can change the offset (such
as tool compensation or workpiece origin offset) for the currently valid offset number or
workpiece coordinate system among those specified, by adding an amount of axis
movement made by manual feed automatically.
2. Explanation
2.1 Active offset change mode
This mode is specified by an active offset change mode signal. In this mode, an amount
of axis movement made by manual feed is automatically added to the offset (such as tool
compensation or workpiece origin offset) for the currently valid offset number or
workpiece coordinate system among those specified. The types of manual feed valid with
this function include manual handle feed, incremental feed, and jog feed.
2.2 Specifying an offset to be changed
An active offset selection signal is used to select a tool compensation or workpiece origin
offset. The selection way of the axis changing a tool compensation can be selected by the
setting of parameter as follows.
• In case of changing a tool compensation of the moving axis:
Parameter ATP (No.5041#1)=0
• In case of changing a tool compensation of the axis selected by DI signal:
Parameter ATP (No.5041#1)=1
In active offset change mode, the selected offset is indicated by blinking its status
indication as follows.
• In case of changing a tool compensation of the moving axis:
Parameter ATP (No.5041#1)=0
Selected offset Status indication
Tool compensation TOFS
Workpiece origin offset WZR
