Abstract
A plurality of path patterns (MCR.sub.1 -MCR.sub.3), in which at least data specifying tracing areas serve as variables, are registered in a memory (102) beforehand, tracer machining data including call instructions (MCC.sub.1 -MCC.sub.3) for calling a predetermined path pattern, as well as actual numbers, are stored in a memory (101) in advance, and tracer machining data are read block-by-block to perform tracer control. When a path pattern call instruction is read, the predetermined path pattern is read out of the memory (102), the variables are replaced by actual numbers to obtain a tracing area, and tracing is performed in the tracing area on the basis of the read path pattern.
Claims5
A tracer control method for performing tracing machining in accordance with a tracing machining program comprising a plurality of blocks, said method comprising the steps of:
- preregistering, in a memory, a plurality of tracing path patterns in which at least data specifying tracing areas serve as variables;
- inserting, in the tracing machining program, command data for calling one of the tracing path patterns and assigning actual values to variables which are used in the path pattern called;
- reading out tracing machining program data block by block and performing tracing machining in accordance with the data;
- calling a tracing path pattern specified by the command data and assigning actual values specified by the command data to variables used in the path pattern called when the command data for calling a tracing path pattern and assigning the actual values to the variables in the tracing path pattern is read;
- and
- performing tracing machining in a tracing area specified by the actual values, on the basis of the tracing path pattern called.
