Generally, most of machining processes are done according to the dimension of the draft made by CAD. However, there are many cases that samples are given without the draft because of the simplicity of the shape in the machining of 2D objects. To get a geometric image for a large object with a dimensional accuracy, it is necessary to use multi-frame images by a robot. This article proposes the method to compose the geometric information using multi-frame images and to extract the dimensional draft for the machining. When the product after cutting was compared with the original sample, the experiment shows that the size of two objects was coincided within the allowed error bound.
