Abstract
According to this invention, common tool codes for specifying tools are used in a whole system, a T code command including tool codes, tool shape information and tool machining ability information are inputted into each NC machine, and this information is converted into local information of individual NC machines to perform machining. The tool codes and the tool information can be subjected to centralized control as a whole in the system.
Claims7
An NC machining controller for an NC machining system including a plurality of NC machining apparatuses each having a tool changer for allowing automatic selection of a desired tool from a plurality of magazine pots, the NC machining controller comprising:
- a first computer for performing general control over the plurality of NC machining apparatuses,
- the first computer having:
- a tool code memory for storing data on correspondence between tools and tool codes;
- a tool information memory for storing tool shape information and machining ability information for each of the tool codes;
- and
- automatic programming means for generating an NC machining program including a T code command to which a specified tool code is added and for outputting the NC machining program to the NC machining apparatuses together with the tool shape information and machining ability information corresponding to the specified tool, and
- a second computer connected to the first computer and provided in each of the NC machining apparatuses,
- the second computer having:
- a magazine address memory for storing data on correspondence between the tool code and a magazine address of the associated tool changer;
- T code command generation means for converting the tool code added to the T code command in the NC machining program into a magazine address of the tool changer corresponding to the tool code on the basis of contents stored in the magazine address memory and for generating a T code command for specifying the converted magazine address;
- tool correction command generation means for generating a tool correction command on the basis of the tool shape information received from the computer;
- and
- machining condition command generation means for generating a machining condition command on the basis of the machining ability information received from the computer,
- wherein each of the NC machining apparatuses and associated one of the tool changers are driven according to the NC machining program including the generated T code command, tool correction command and machining condition command.
