Method and system for numerical control of machine tool

A numerical value control system that controls a machine tool, by calculating a move command from a work program or a work data for a numerical value control unit, the numerical value control system comprising:

• servo motors for controlling movements of the machine tool;
• a binary data preparing unit that includes a work data analyzing unit for analyzing a program or a data including a CAD (Computer Aided Design) program or a CAD data, an interpolating unit for carrying out interpolation for each axis based on output information from the analyzing unit and cut conditions, an accelerating/decelerating unit for generating speed information per unit time in advance by processing an output of the interpolating unit, and a feed-forwarding unit for carrying out feed-forward compensation to an output of the acceleration/deceleration unit;
• a database unit that includes a memory unit for storing data prepared by the binary data preparing unit;
• and
• an NC unit that includes a buffer memory unit for storing an output data from the database unit, a machine control section for managing and delivering the data within the buffer memory unit, a servo control section for controlling the servo motors based on the data delivered from the machine control section, and a work program analyzing unit for analyzing a work program, wherein
• the machine control section is configured to be capable of using the data including a move command of a binary format prepared in advance and stored in the database unit, instead of analyzing a work program at the work program analyzing unit.
