Abstract: | A simple improved method is suggested for determining constant cutting force coefficients, irrespective of the cutting condition
and cutter rotation angle. This can be achieved through the combination of experimentally deternimed cutting forces with those
from simulation, performed by a mechanistic cutting force model and a geometric uncut chip thickness model. Additionally,
this study presents an approach that estimates runout-related parameters, and the runout offset and its location angle, using
only one measurement of cutting force.
This method of estimating 3D end milling force coefficients was experimentally verified for a wide range of cutting conditions,
and gave significantly better predictions of cutting forces than any other methods. The estimated value of the runout offset
also agreed well with the measured value. |
