Computation device, machine tool, control device for machine tool, and compuration program

A computing device (110) computes a position (C) of a tool (C1) that cuts a ridge line (RL) formed by a peripheral wall face (SW) and a cylinder peripheral face (SS) forming a through hole (HE), having the shape of a column (CS), penetrating through a workpiece (CP). The computing device (110) calcu...

Zusammenfassung:	A computing device (110) computes a position (C) of a tool (C1) that cuts a ridge line (RL) formed by a peripheral wall face (SW) and a cylinder peripheral face (SS) forming a through hole (HE), having the shape of a column (CS), penetrating through a workpiece (CP). The computing device (110) calculates the position on the basis of: a first basis vector (e1) and a second basis vector (e2) on a plane (VP) perpendicular to a tangent (TL) to the ridge line; workpiece data; an ellipse (E2) formed by the plane and the column; a predetermined processing width (W); and a radius (D) of the tool.
