Title:
MACHINE TOOL AND TOOL MOVEMENT PATH DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2023056848
Kind Code:
A
Abstract:
To provide a technique that can improve the degree of freedom in processing a work-piece in an eccentric shape.SOLUTION: A control part (70) of a machine tool (1) obtains coordinates of a first process starting point SpA and a first process ending point EpA in eccentric shapes in a reference phase (θ=0°) of a work-piece W1 with a spindle central line AX0 as a center and coordinates of a second process starting point SpB and a second process ending point EpB in eccentric shapes in an antiphase (θ=180°); determines a movement path for a tool TO1 according to rotation of the work-piece W1, at least on the basis of the coordinates of the first process starting point SpA, the coordinates of the second process starting point SpB, the coordinates of the first process ending point EpA and the coordinates of the second process ending point EpB, so that the work-piece is formed in an eccentric shape (W1p) with an eccentric shaft AX3, which passes through a central starting point SpO between the first process starting point SpA and the second process starting point SpB and a central ending point EpO between the first process ending point SpA and the second process ending point EpB, as a center; and performs control by which a tool TO1 is moved in accordance with rotation of the work-piece W1.SELECTED DRAWING: Figure 8
