From the results related to the economics of hypereutectic
Al-Si alloy machining, the following conclusions emerge.
In the machining of hypereutectic Al-Si alloy the life of a
single-crystal diamond tool is much affected by the depth
of cut, but less so by the feedrate. The tool-life equation
obtained is:
V T0.7657 f 0.8187 d 0.6076 = 600.2
In the machining of swashplates, the cross-section of the
cut (feed rate ´ depth of cut) is an important factor in the toollife
criterion. The production cost and tool ability are improved
more by increasing the cutting speed than by increasing the
feedrate.
