Abstract
A test run control method tests a computerized numerical control (CNC) apparatus to check a generated NC program. Data are read block by block from an NC program in response to a test run start command (ST1), the data are converted into execution blocks while forwarding a tool in a forward travel, and the data in the form of execution blocks and model data necessary for a preliminary processing are stored in a reverse function memory. The tool is reversed in a reverse travel based on the data in the form of execution blocks stored in the reverse function memory in response to a reverse command (ST2). The reverse travel is stopped at a given time (P11) in response to a stop command (ST3) to allow the NC program to be edited in a prescribed range. The program is editged in the prescribed range (N112) with an editing function. The preliminary processing is effected on the basis of the modal data stored in the reverse function memory in response to a test run restart command (ST5), and the edited NC program is executed. With the above method, the NC program can be checked and modified in a simple operation.
