Machining estimation apparatus, machining estimation method, and machining estimation program

A machining estimation method, comprising:

• photographing, by a camera, a part to be estimated and a dimension reference marker, the part to be estimated being produced by cutting a sheet metal in advance;
• generating, by an image processing unit, edge data by extracting an edge of the part photographed by the camera;
• enlarging or reducing, by the image processing unit, the edge data based on a size of the dimension reference marker photographed by the camera such that a size of the edge corresponds to an actual size of the part;
• and
• calculating, by a machining time calculation unit, a length of a cutting line for cutting out the part from the sheet metal based on the edge of the edge data corresponding to the actual size of the part, and calculating, by the machining time calculation unit, a machining time for producing the part by cutting the cutting line in accordance with a material and a thickness of the sheet metal.

A non-transitory computer-readable medium having stored thereon a machining estimation program causing a computer to execute:

• a step of generating, based on photographed image data obtained by photographing a part to be estimated and a dimension reference marker by a camera, edge data by extracting an edge of the part to be estimated, the part to be estimated being produced by cutting a sheet metal in advance;
• a step of enlarging or reducing the edge data based on a size of the dimension reference marker in the photographed image data such that a size of the edge corresponds to an actual size of the part;
• a step of calculating a length of a cutting line for cutting out the part from the sheet metal based on the edge of the edge data corresponding to the actual size of the part;
• and
• a step of calculating a machining time for producing the part by cutting the cutting line in accordance with a material and a thickness of the sheet metal.
