Control device for a machine tool
A control apparatus for controlling a machine tool on the basis of a machining program is provided with a program analysis unit which analyzes an input machining program, a process table creation unit which, on the basis of the results of the analysis by the program analysis unit, creates a process table that sequentially lists processes according to the execution flow of the machining program, and a display unit which displays the process table created by the process table creation unit.
1. A control device for controlling a machine tool based on a machining program, comprising:
a program analyzing section for analyzing the machining program which has been input;
a process chart creating section for determining whether or not the machining program includes a tool changing command or a command for changing angle of surface to be machined, based on the analyzing by the program analyzing section, and creating a schedule by arranging processes of the machining program in an execution sequence of the machining program, wherein the machining processes are sorted in the schedule according to tools to be changed if a tool machining command is included in the machining program or according to the surface to be machined if a command for changing angle of the machined surfaces is included; and
a displaying section for displaying the schedule created by the process chart creating section and the machine program at the same time.
2. The control device according to claim 1 , further comprising an input section, the machining program being input through the input section along with tool data and workpiece data.
3. The control device according to claim 1 , wherein it is determined whether or not a value of the tool number is stored in the memory region, when a tool changing command is detected, and an error is indicated if no tool number is stored in a memory region.
