Analysis of Work Accuracy Dependencies on Design of a Device for Control of Workpiece Dimensions and Compliance at Machining

Abstract:

Work accuracy dependencies of a new scheme device for automatic dimension control and follow rest at machining of multi step shaft are analyzed. The device can automatically reset from control and the support of one step of a shaft to the other and can be used on programmed cylindrical grinders or lathes. Errors connected with the kinematics scheme and showing in static and uprising at working of a device are analyzed and ways of their decreasing are shown.
