CO2 Rail Car Dragster

Welcome to cudacountry's SOLIDWORKS 2019 and Mastercam 2020 CO2 Rail Car Tutorials. We use SOLIDWORKS 2019 to design our cars and Mastercam 2020 to create CNC toolpaths to cut the car body.

19. SW2019 to Mastercam 2020. Open your SW body file in Mastercam 2020. In Mastercam the solid car body is rotated into the correct Mastercam XY axis and moved to Mastercam origin. Then create check solid to keep tool away from fixture. Finish off with creating WCS plane. Units are metric. This tutorial also works with Mastercam 2019.
20. Car body toolpaths for Mastercam 2020. Units are all metric. Toolpaths to cut rail car body from balsa blank: 1) Cut body left side using finish Equal Scallop toolpath. 3) Mirror left cut to right side cut. This tutorial also works with Mastercam 2019.
