DETERMINING WORKPIECE MATERIAL PARAMETERS WHICH AFFECT SELF-INDUCED VIBRATION.

A new rapid experimental method is proposed for determining force delay constants, friction coefficient and chip pressure, on which vibration in cutting depend. In particular, it is possible to find the paths taken by the tool during the cutting and friction force delay times. These parameters were determined for a number of standard materials, including mild and creep-resisting steels, cast-iron and titanium alloy.
