NUMERICAL CONTROL APPARATUS WITH AUTOMATIC PROGRAMMING FUNCTION.

摘要

An NC apparatus with an automatic programming function is provided with an automatic programming unit (101) which executes the automatic programming and an NC unit (102) which executes NC processing. The apparatus includes: a nonvolatile memory (102g) which is provided for only one of the automatic programming unit and the NC unit to store data, such as a material file and a tooling file, required for the automatic programming and data required for the NC processing; a common memory (101e) which can be accessed by both a processor (101a) in the automatic programming unit and a processor (102a) in the NC unit; and a bus changeover controller (101d) which provides bus changeover control such that a predetermined processor is able to access the common memory. The unit on the data transmission side stores data in the common memory (101e), while the unit on the data reception side reads the data out of the common memory, so that data transfer is carried out between the two units.
