Programming technological functions (cycles)
10.3 Contour milling
10.Stock removal
11.Contour pocket 2
12.Stock removal
If you are doing all the machining for the pocket at once, i.e. centering, rough-drilling and
removing stock directly in sequence, and do not set the additional parameters for centering/
rough-drilling, the cycle will take these parameter values from the stock removal (roughing)
machining step. When programming in G code, these values must be specifically re-entered.
Note
Execution from external media
If you execute programs from an external drive (e.g. local drive or network drive) then you
require the execution from external storage function (EES).
