Separate tool offsets are internally provided for machining and
background drawing. Upon starting drawing or when selecting a program
for drawing, the tool offset data for machining is copied to the tool offset
data for background drawing. Changing a tool offset by using a G10
command during machining does not affect that for background drawing.
Similarly, changing a tool offset by using a G10 command during drawing
does not affect that for machining.
The same parameters are used for both background drawing and actual
machining.
Workpiece coordinate system offsets, part of the parameters, are provided
separately for machining and background drawing. Upon selecting a
program for drawing, the workpiece coordinate system offset data for
machining is copied to the workpiece coordinate system offset data for
background drawing. Changing a workpiece coordinate system offset by
using a G10 command during machining does not affect that for
background drawing. Similarly, changing a workpiece coordinate system
offset by using a G10 command during drawing does not affect that for
machining.
Macro variables are provided separately for machining and background
drawing. Upon selecting a program for drawing, the macro variables for
machining are copied to the macro variables for background drawing.
Changing a macro variable by using a G10 command during machining
does not affect that for background drawing. Similarly, changing a macro
variable using a G10 command during drawing does not affect that for
machining.
When bit 6 (BGOF) of parameter No. 3109 is set to 1, pressing the
OFFSET
SETTING
function key on the background drawing screen displays the tool offsets,
workpiece coordinate system offsets, and macro variables for background
drawing. In such a case,
BGGRP
is displayed at the bottom right of the
screen, to indicate that data for background drawing is being displayed.
