The machining process exhibits piecewise behaviour and cannot be linearly extrapolated in a wide range. It cannot be modelled effectively using theories and equations. Thus, expert systems have emerged as a major tool for decision-making in such complicated situations (Singh & Raman, 1992). The conventional method for selecting machining parameters such as cutting speed and feed rate is based o...

The purpose of this study was to evaluate grinding efficiency in abutment teeth comprising both dentin and core composite resin in the axial plane. Grinding was performed over 5 runs at two loads (0.5 or 0.25 N) and two feed rates (1 or 2 mm/sec). The grinding surface was observed with a 3-D laser microscope. Tomographic images of the grinding surfaces captured perpendicular to the feed directi...

In this study, machinability tests were carried out to investigate the effects of control factors (cutting tool geometry, cutting speed, and feed rate) on surface roughness (Ra), deviation from dimensional accuracy (Da_dev), roundness error (Re) in drilling CFRP/Ti6Al4V mixed metallic stack determine optimum levels parameters. The each factor their interactions three quality characteristics ana...
