Abstract

Machinability is an important property of materials, especially because it affects the manufacturing cost of products. Since there is no accepted definition of machinability, there is no accepted test for measuring it. Researchers have studied two dimensional cutting forces, chip thickness, using orthogonal cutting models, others have concentrated on comparing three dimensional cutting forces, surface roughness and power consumption in oblique cutting. All these tests converge in the necessity of determining which material has better machinability. In this paper machinability tests by other authors are reproduced, proper modifications are made, to visualize which test should be considered and which to discard in the measurement of machinability. Keywords: cutting force, thrust force, surface roughness, cutting temperature, orthogonal cutting, emissivity, chip morphology, dynamometer.
