The MANUALplus requires information on the specific tools for a
variety of tasks, such as calculating the cutting radius compensation
or the proportioning of cuts.
Tool length
All programmed and displayed position values are given with respect
to the distance between the tool tip and workpiece zero point. Since
the control only knows the absolute position of the tool carrier (slide),
the MANUALplus needs the dimensions XL and ZL (see figure) to
calculate and display the position of the tool tip.
Tool compensation
The tool tip is subjected to wear during machining processes. To
compensate for this wear, the MANUALplus uses compensation
values. The compensation values are managed independent of the
values for length. The system automatically adds the compensation
values to the values for length.
