Abstract
A numerical control system for machining a workpiece including a reader for reading a machining control program for the workpiece, a control device for supplying a control signal to a machine tool for the workpiece, and a storage device disposed internal or external to the control device, for storing a conversion table for converting a first character string read from the program into a second character string representing a command. The control device operates in response to the reader reading the first character string to supply the control signal to the machine tool in accordance with the command of the second character string. The second character string may represent, e.g., a delete command or a repeat instruction command.
Claims22
A numerical control system for machining a workpiece, the system comprising:
- a predetermined machine tool for machining the workpiece;
- means for reading a machining control program for the workpiece, the machining control program including a first predetermined character string representing a symbolic character string that is generic to multiple machine types, not a specific machining command that is executable by one particular machine type;
- control means for supplying a machining control signal to said predetermined machine tool in accordance with a read machining control program;
- and
- conversion means, coupled to said control means, for storing a conversion table having information for converting said first predetermined character string read from the machining control program into a second predetermined character string, the second predetermined character string representing a specific machining command which can be performed by the predetermined machine tool, said control means supplying a machining control signal to said predetermined machine tool in accordance with the specific machining command.
A numerical control system for machining a workpiece, the system comprising:
- a predetermined machine tool for machining the workpiece;
- means for reading a machining control program for the workpiece, the machining control program including a plurality of machining instructions and a first predetermined character string;
- control means for supplying a machining control signal to said predetermined machine tool in accordance with a machining instruction of a read machining control program;
- and
- conversion means for storing a conversion table having information for converting the first predetermined character string read from the machining control program into a second predetermined character string corresponding to one of skip and repeat control signals to be supplied to said predetermined machining tool, said control means supplying said one of the skip and repeat control signals to said predetermined machine tool in accordance with the second predetermined character string.
