6.3 Simple workpiece machining in manual mode
In "manual" mode, you can directly carry out simple machining
processes without having to write a program.
The following functions are available to you for machining in manual
mode:
Axle movements
Taper turning
Straight (face or longitudinal turning)
Tool, spindle speed, and direction of spindle rotation are activated by
"Cycle Start".
A change in feedrate immediately becomes active.
