Modelling of Thrust Force during Drilling of Fibre Reinforced Plastic Composites

open access: yes, 2013
Delamination during drilling of composite materials is critical problem. Thrust force acting on workpiece being drilled plays a key role in delaminating the composite, therefore its modelling is of great importance.

Investigation of the effects of machining parameters on the thrust force

open access: yes, 2014
In this study, the effects of workpiece hardness, drill diameter, drill length and drilling parameters on thrust force and cutting torque are investigated in the drilling of AISI D2 and AISI D3 cold work tool steels under dry drilling conditions. The experiments are performed at three cutting speeds (5, 10 and 15 in/rnin) and three feed rates (0.04, 0 ...
