Title:
NUMERICAL CONTROL DEVICE AND PRODUCTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/140390
Kind Code:
A1
Abstract:
A numerical control device is provided with a machining program read section (2) for reading an order (11) ordered from a machining program (1), an order path storage section (3) for storing pre-compression order paths (12) in a pre-compression order path buffer (20), a compression processing section (4) for creating one new post-compression order path (13) connecting the starting points and end points of a plurality of continuous order paths, a movement data creating section (5) for correcting the post-compression order path (13) to a tool moving path so as to create tool movement data (15) required to interpolate the tool moving path, and an interpolation processing section (6) for interpolating a tool moving path when the compression processing section (4) has not compressed the order path to find a tool position (16) using the pre-compression order path (12) stored in the order path storage section (3) in combination with the tool movement data (15) relating to the tool moving path after compression, which has been created by the movement data creating section (5).
