Working control device

A computer readable medium comprising 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 a working of a prior formed object workpiece conducted in the past;
• determining the working conditions based on the working case;
• controlling a working machine on the basis of the working conditions;
• obtaining from a monitoring unit information of the working machine when the control program controls based on the working conditions;
• and
• storing in a working case registration unit having the working case storage unit the working machine information obtained by the monitoring unit in a way that makes it as a working case mapping to the configuration information.
