Computing offsets of b-spline curves

WebAug 23, 2024 · Thus, the students should be given the other option to create the tool-path by applying Equations (1)–(7). The emphasis should be given to both how to model the shapes using some piecewise B-spline curves, and then to create the offset curve D (t). The students should create the CNC program, too, using the information of offset curve D (t).
