Environmental-Friendly Cutting of Automotive Parts Made of Aluminium Castings	2010	7	.pdf	application/pdf	4094	208	47	Figure 2: Surface roughness under high speed cutting conditions Cutting conditions: vc = 1000–2000 m/min; rε = 0.4 mm An important factor, to be considered during the design of the insert, is the nose radius, its increase affects favourably the surface roughness. Due to space limitations it is not possible to analyse the tool edge quality (surface roughness values on the rake face and flank land of the inserts, roughness of main cutting edge, edge sharpness, edge radius etc.) a) different nose radii (rε = 0.4 and 0.8 mm) b) different versions of rake face Figure 3: Surface roughness vs. insert geometry Cutting conditions: vc = 1400 m/min a) maximum heights of profile b) profile kurtosis Figure 4: Surface roughness versus relief angle The effect of the tool material The first material, coming into question, is the poly- crystalline diamond (PCD): it has anti-adhesion characteristics, chemical inertness, compared to cemented carbide better abrasive wear resistance and low friction coefficient.	cache/hjic-283.pdf	txt/hjic-283.txt
