Input simple
For simple machining operations, you have the option to reduce the wide variety of parameters
to the most important parameters using the "Input" selection field. In this "Input simple" mode,
the hidden parameters are allocated a fixed value that cannot be adjusted.
If the workpiece programming requires it, you can display and change all of the parameters
using "Input complete".
Machining type
For solid machining, you can select the machining type (roughing or finishing). If you want to
rough and then finish, you have to call the machining cycle twice (block 1 = roughing, block 2
= finishing). The programmed parameters are retained when the cycle is called for the second
time.
During insertion with oscillation, the message "Ramp path too short" will appear if the tool is
less than the milling cutter diameter away from the insertion point along the ramp, or the
machining depth is not reached.
● Reduce the insertion angle if the tool remains too close to the insertion point.
● Increase the insertion angle if the tool does not reach the machining depth.
● If necessary, use a tool with a smaller radius of select a different insertion mode.
