Abstract
A method of forming configuration data for a CNC machine tool having a CNC (computerized numerical control unit) comprising a CPU (central processing unit), a memory, input/output means, and servo drive means. According to final configuration data train inputted for a workpiece, an edge-corrected configuration data block train is formed with the edge configuration of a cutting tool taken into accound, and configuration data are formed for a remainder which is created in said workpiece because of the edge configuration correction, so that the workpiece is automatically machined.
Claims6
A method of forming configuration data for a computerized numerical control (CNC) machine having a CNC unit comprising a central processing unit (CPU), a memory, input/output means, servo drive means and a cutting tool driven by the drive means, comprising:
- (a) inputting to said CNC unit first data related to a final workpiece configuration and second data representing the edge configuration of said cutting tool;
- (b) forming by said CNC unit on the basis of said first data a first data block train for a final workpiece configuration;
- (c) forming by said CNC unit on the basis of said first data block train and said second data a second data block train comprising edge-corrected configuration data;
- and
- (d) forming from said second data block train and said first data block train remainder data defining a remainder which is created in said workpiece because of the edge configuration correction.
A method of forming configuration data for a computerized numerical control (CNC) machine having a CNC unit, comprising a central processing unit (CPU), a memory, input/output means, servo drive means and a cutting tool driven by the servo drive means, and operative to automatically cut a workpiece into a final configuration, defined by final configuration data inputted for the workpiece, according to an edge-corrected configuration data block train formed by the edge configuration of a cutting tool taken into account, the improvement comprising:
- forming a correction data block having index data, for a correction object;
- adding said correction block to said edge-corrected configuration block train;
- forming a storage data block for storing said final configuration data corresponding to said correction object;
- forming a conversion table for searching for the address of said storage data block on the basis of said index data;
- extracting data of said correction data block from said edge-corrected configuration data block;
- extracting said storage data block corresponding to said correction object obtained using said conversion table;
- and
- forming configuration data for a remainder which is created in said workpiece because of the edge configuration conversion.
