<p>PURPOSE:To improve operating efficiency by excluding wasteful waiting time at the time of the exchange of a tool as to punch press working. CONSTITUTION:When a command to execute the multi-product working of a punch press machine is issued, a custom macro stored in a memory in a numerical controller is read (S3), and if it is a tool exchange command (S4), the tool is exchanged without moving a work table fixing a material (S5), and simultaneously, working order is reversed (S6), and actual working is executed in the working order in a forward direction and a backward direction by one tool (S7), and since if the custom macro is not finished, operation is transferred to the execution of the next working command (S8), and if all of the working is not finished, the operation is transferred to the execution of the next custom macro (S9), the wasteful waiting time at the time of the exchange of the tool can be excluded, and the operating efficiency can be improved.</p> |
