The equations apply for longitudinal turning operations
as well as face turning operations. Drilling operations
on the face of the workpieces can also be calculated.
Overlaid, simultaneous processing, e.g. through multi-
ple tools or turrets, must also be mathematically over-
laid, i.e. the required radial clamping forces of the indi-
vidual machining procedures must be added.
However axial drilling and turning jobs are rarely over-
laid; because as a rule, they cannot run simultaneous-
ly, due to opposite directions of rotation.
For the calculation, the point with the highest forces,
i.e. the most unfavorable torque of the machining, must
serve as the mathematical basis. If in doubt, a check of
multiple cutting edge engagement situations is required
to determine the most unfavorable.
If radial drilling operations are undertaken, in addition
to determination of the required, radial clamping force
