<p>PURPOSE:To make it unnecessary to input a cutting condition at every process of a machining program, by installing a controlling device which reads out the cutting condition to work types at every material according to a storing device of work types and materials of the command machining program and makes a machine perform its operation. CONSTITUTION:When a machining program is started, work zero positions X and Y and materials are read out and then a process number N=0 is registered, whereby work data of a process number N=1 are read in a central processing unit 3 from a machining program memory 2. Next, whether it is the same machining method as the last time and a hole diameter or not is calculated, and if an answer YES is the case, machining for the specified position takes place according to the cutting condition. And when an answer NO is the case, a new tool is selected and attached to a spindle. And, from a cutting condition table, in which cutting conditions pertaining to materials and work tools are stored in a cutting condition memory 1, peripheral velocity and feed rate are read out and read into the CPU3. Then, machining for then specified position takes place according to the cutting condition. Thus, the machining program is stored in advance as separating from the cutting condition so that kit is unnecessary to input the cutting condition at every process.</p> |
