Please see → Choosing CAM Softare Understanding 2.5DĢ.5D is a term used in the CAD-CAM-CNC workflow to describe parts that comply to the following restrictions: Intro to Building Tool Paths in Cambam Why we choose Cambam This is a manual process and is required since dxf files are for 2D only and do not contain any third axis information. dxf imported in Cambam to generate the Tool PathsįreeCAD will also be needed as constant reference to extract the 3D information. stl as reference file to compare the part described with the. By including FreeCAD in our workflow we can be sure by the time we release the files they are completely usable in FreeCAD. We plan to release the CAD file to the Open Source CNC and 3D printing community.FreeCAD does everything we need it to do in the CAM department at zero cost.The CAM department uses FreeCAD instead of SolidWorks for a number of reasons: When complete we hand over the CAD design to the CAM department. We make all our mechanical CAD design and design verification in SolidWorks. File Conversions Export IGS from SolidWorks to FreeCAD Part: The CNC cut component from which we build our product case. nc: is the file format we chose to hand over the part as numeric control file from CAM → CNC.ĬNC Cut: The process where a Computer Numeric Controlled Machine moves a tool along a tool path, cutting away all stock material which is not needed and revealing the part. Verification is to find these Errors before cutting the part in CNC to avoid high costs. nc file.ĬAM Verification: Since the generation of Tool Paths is a manual process, errors can happen. Once done the toolpaths are saved in the. dxf, imports it into Cambam and then adds CNC attributes to it such as feed and spindle speed. The CAM engineer exports a feature outline from FreeCAD in. The CNC Machine load the nc file and follows the Tool Paths with its tools and thus cutting everything away which is not needed.īuilding Toolpaths: is a complicated job that requires a lot of skill and experience.
dxf files plus 3D info.ĬAM: The CAM (Computer Aided Manufacturing) process generates Tool Paths saved in a. igs File: This file format works well to transfer the design of one part from CAD → CAM.įile Conversion: The CAM department uses FreeCAM to convert the. We use SolidWorks for complex designs such as ViCase and FreeCAD for simple designs, such as Fixtures to help manufacturing, say assembling ViCase. We use GitHub and Trello to organize, coordinate, delegate and synchronize our work.ĬAD: We design the part or a complete assembly of parts in Computer Aided Design. Specs Specifications and to do lists to complete the design.
