Working control device

A working control program for making a computer execute steps of:

• obtaining configuration information about characteristics of a three-dimensional configuration from design data of an object workpiece;
• searching out a working case on the basis of the configuration information from a working case storage unit storing working conditions, as a working case, of the working conducted in the past;
• determining the working conditions based on the working case;
• and
• controlling a working machine on the basis of the working conditions.
