Method for checking interference, method for checking processing program, and method for checking processing propriety

A method for checking a processing program, comprising the steps of:

• obtaining a configuration and size of a processing material by sensing a three-dimensional image of the processing material and converting the three-dimensional image into three-dimensional coordinates as well as obtaining a product's configuration and size defining the three-dimensional shape of the product after having completed the processing;
• determining whether the difference between said processing material's configuration and size and the product's configuration and size at the same coordinate position is larger than a standard margin to enter preliminarily prescribed or not by an arithmetic processing by an arithmetic processing means;
• and
• when said difference is larger than the standard margin, issuing a command to change the processing program.

A method for checking processing propriety, comprising the steps of:

• obtaining a configuration and size of a processing material by, sensing a three-dimensional image of the processing material and converting the three-dimensional image into three-dimensional coordinates, as well as obtaining a product's configuration and size defining the three-dimensional shape of the product after having completed the processing;
• determining whether the difference between said processing material's configuration and size and the product's configuration and size at the same coordinate position is larger than a prescribed value by an arithmetic processing of an arithmetic processing means;
• and
• when the difference between said processing material's configuration and size and the product's configuration and size at the same coordinate position is larger than the prescribed value, determining whether it is a preparation error of said processing program or it is an abnormal shape of the processing material.
