摘要:
A numerical control system for executing numerical control processing on the basis of a command program, and for actuating a machine in accordance with the results of the processing steps to machine a workpiece in the manner specified by the instructions in the command program. There are prepared a plurality of system variables, the values of which represent a variety of operational conditions of the machine or of a numerical control device. A user macro, having at least an identification and an instruction that employs the system variables, is stored beforehand in a memory. The command program is programmed to include a user macro call instruction. A prescribed user macro is read out from the memory by means of the user macro call instruction, thereby to allow processing in accordance with the user macro. For example, it is possible to execute processing upon reading out input/output interface signals, clock time and a variety of machine positions.

A laser machining control method using a numerical control system for controlling an X-Y table. A command program (2) in a memory is read out for each one block to cause a lamp on an operation panel (5) to be lit. An operator changes, sets and inputs an output power (S), a frequency (P) and a pulse duty (Q) depending on required conditions. The input conditions are applied to a high-frequency power source (6), and laser machining is carried out under these conditions.

A laser oscillation control system performing laser beam machining by controlling an X-Y table by a numerical control system.An output of a laser oscillator is controlled by a G-code included in a program from a command system input to a numerical control system. An output power is commanded by an address S, a frequency by an address P and a pulse duty by an address Q. These command data are fed to a high-frequency power source to control a laser output.
摘要:
The present invention allows a programmable controller in a stored program system to easily execute even complex sequence control. A memory (50) has stored therein a first program of the ladder type and a second program described in another program language such as PASCAL or FORTRAN. First and second setting devices (51) and (52) set the execution times for processing by the first and second programs, respectively. A management device (53) executes the processing according to the first and second programs alternately for the periods of time set by the first and second setting device (51) and (52).
