8.2 Point Tables
Function
You should create a point table whenever you want to run a cycle, or
several cycles in sequence, on an irregular point pattern.
If you are using drilling cycles, the coordinates of the working plane in
the point table represent the hole centers. If you are using milling
cycles, the coordinates of the working plane in the point table
represent the starting-point coordinates of the respective cycle (e.g.
center-point coordinates of a circular pocket). Coordinates in the
spindle axis correspond to the coordinate of the workpiece surface.
Creating a point table
Select the
Programming and Editing
mode of operation.
To call the file manager, press the PGM MGT key.
Enter the name and file type of the point table and
confirm your entry with the ENT key.
To select the unit of measure, press the MM or INCH
soft key. The TNC changes to the program blocks
window and displays an empty point table.
With the soft key INSERT LINE, insert new lines and
enter the coordinates of the desired machining
position.
Repeat the process until all desired coordinates have been entered.
File name ?
With the soft keys X OFF/ON, Y OFF/ON, Z OFF/ON
(second soft-key row), you can specify which coordinates
you want to enter in the point table.
