Method and apparatus for automatically producing a machining program

摘要

A method and apparatus able to quickly and accurately automatically produce machining programs for complicated shapes of products without being affected by the level of knowledge or experience of the operator. A cutting-condition determination processing unit ( 20 ) of an automatic programming apparatus ( 10 ) specifies required standard cutting condition data from the type of material and the types of processes designated by an input unit ( 12 ) in a cutting condition data table ( 24 ) stored in a storage unit ( 18 ), specifies the tool data corresponding to the types of tools designated by the input unit in the tool data table ( 26 ) stored in the storage unit, and determines the cutting conditions relating to the type of material and the tools from the standard cutting condition data and the tool data. A program-generation processing unit ( 22 ) specifies a program-generation algorithm corresponding to the designated process in an algorithm table ( 28 ) stored in the storage unit and generates machining programs based on the determined cutting conditions in accordance with the program-generation algorithm.
