As this is a static examination the safety factor for this estimate should be
S >> 3 .
Drilled with a cutting force of 6,1 kN at a height of 0,5 m (Depending on material, tool
and cutting parameters). Also acts a weight force of the workpiece (F
G
).
As a simplification it will be calculate with only one clamping point. The remaining
double clamping pots are used for additional security.
