In the Basic arithmetic folder of the Insert NC function window, the control offers the functions FN 0 to FN 5.
You can assign numeric values to variables using the FN 0 function. You then use a variable instead of the fixed number in the NC program. You can also use pre-assigned variables, e.g. results from touch probe cycles. With the functions FN 1 to FN 5, you can make calculations with the variable values within the NC program.
