TOOL SHAFT ATTITUDE DETERMINATION DEVICE, TOOL SHAFT ATTITUDE DETERMINATION METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a tool shaft attitude determination device which determines tooling and a tool shaft attitude suitable for a control target curved surface, and easy to secure rigidity.;SOLUTION: A control part 3 divides a curved surface 41 into polygons 43, moves a spherical inclusion body 49 including a tool tip along a tool path 51 on the curved surface 41, and detects the polygon 43 close to a tool holder to determine the control target curved surface. Next, the control part 3 calculates a curved surface vector having magnitude according to an area of the polygon, with the normal direction of the polygon as a direction. The control part 3 calculates a total of the curved surface vectors 53 of the polygons 43 included in the control target curved surface, and determines it as a tool shaft attitude vector 55. Here, a direction of the tool shaft attitude vector 55 is the tool shaft attitude easy to secure the rigidity.;COPYRIGHT: (C)2008,JPO&INPIT
