Title:
MACHINE TOOL AND MACHINING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/030866
Kind Code:
A1
Abstract:
A control unit (72) causes a headstock (20), a tailstock (30), and a tool (43) to make relative movements, thereby machining the peripheral surface of a workpiece (W) in the radial direction. This control unit (72) performs control in such a way that the relative radial feed rate for the tool (43)in a transient state (T21) is higher than the relative radial feed rate for the tool (43)in a steady state (T22), the transient state (T21) being a state where there increases the radial deflection amount of the workpiece (W) at the machining position, and the steady state (T22) being a state where the radial deflection amount of the workpiece (W) at the machining position becomes constant. Due to the above, it is possible to reduce machining time at the time of the start of machining.
