ipt file.ġ) Start with a smaller model to test out this workflow. Then choose another plane to create a new sketch and repeat until you're happy with your design.

In my design, I mirrored my sketches along an axis of symmetry to create a stylized, baroque look.įinish your sketch and extrude it along the z-axis. Constrain one part of your sketch to the origin this is a general good practice. Use constraints to specify coincident points, parallel and perpendicular relationships, tangents, and dimensions. If you're designing your own model, in Inventor start a new sketch and create a design along the xy plane. This software includes 2D and 2.5D CAM strategies. However, if you have access to a CNC machine you can use these steps for your own work by downloading Inventor HSM Express for free. This Instructable was created at the Pier 9 workshop using Inventor Pro 2016 HSM.

ipt file that you can download below, named CAM_practice_part.ipt. However, you can also use this Instructable as a step-by-step guide if you want to just practice CAM without using your own designs yet. The steps in this Instructable will offer a good overall foundation for machining strategies that you can apply to your own designs. You will need to have a basic understanding of parametric modeling in Inventor, so if you've never done this before, try out some tutorials to learn the basics. If you want to use your own design, use my steps as a general guide. This Instructable can be used in two ways. If you're interested in using this workflow for your own project, especially if you'd like more help with the HSM CAM (High Speed Machining) steps-like Setup, Toolpath, and Simulate-this Instructable is for you. This Instructable outlines a logical workflow from model design in Autodesk Inventor HSM to post processing G-code for the Shopbot CNC router. Take ShopBot Basic Use and Safety Class. Requirements for using the tools themselves: This Instructable is for Workshop Users at Pier 9.
