Direct input of offset value measured B
for 2 spindle lathe
Jan.31.02
2/13
1. Outline
In 2 spindle lathe which has the back spindle, each spindle has the workpiece
coordinate system for itself. By using this function, it is available to set
automatically the tool offset and the Z-axis workpiece origin offset corresponding
to each work coordinate system with the touch sensor.
This function is the additional option. This function needs the following
functions.
−
Direct input of offset value measured B (

J933)
−
Workpiece Coordinate System (

J894)
2. Touch Sensor
This touch sensor makes contact in two directions in each axis, and outputs four
signals when it detects a tool contact. The contact faces are selected according to
the tool nose figures to be measured.
