  • Modelling Cutter Paths SOLIDWORKS Forums

    Jun 14 2018 · That was my comment that an end-mill wasn t the plan but was close enough to show the concept. A radiused cutter was the plan but the end-mill caused enough pain to model in. A ball-nose cutter would require a lot more cuts than the single U shaped path. This model was just an example to illustrate the difficulties in modelling cutter paths.
