OPERATION BY Symbolic FAPT
3. EXECUTION OF
After entering machine zero point or turret position data,
check the entered data. Failure to enter correct data may
result in the tool colliding with the workpiece and/or
machine, possibly causing damage to the machine and/or
tool itself, or injury to the user.
When the figure has been defined, the screen asks about the “Home
position” and “Index position”.
The meaning of questions is as follows:
Input the coordinate value of home position of NC lathe.
If a data has already been input properly, press the “Cursor±”. Do not
input data and leave it undefined when not starting from the home
Input the coordinate value of turret revolution center position.
If a data has already been input properly, press the “NEXT PAGE”.
In the case of 15–TTFB, 16–TT CAP II, the question for home position
and index position at the No.2 also appears.
Input the distance from the programmed coordinate axis for
both home position
and index position. Let the sign of Z to
positive whichever direction the Z axis of coordinate axis
programmed faces. The home position is used to indicate
the relationship between the program coordinate system
and machine coordinate system.
When the home position
and index position is determined
and it is troublesome to input these data every time, it is
possible to set initial values to the system parameters 206
– 213. Also, it is possible to skip questions. For details, see
Chapter 8 1–1. This screen does not appear when skipping
the questions of home position
and index position.
