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.
