<\/figure>\n\n\n\nCAD refers to any software that can be used to create 3D models and technical 2D drawings of mechanical components. It\u2019s also critical for the development of complex machine assemblies. <\/p>\n\n\n\n
CAD<\/a> is especially important for designing parts that need to be CNC machined, because machinists must input 3D model data into every CNC device so the machine knows what shape to manufacture. Also, technical drawings are usually developed by designers to indicate the tolerances of all critical features. In some cases, tolerances<\/a> are indicated directly on the 3D model without the need for drawings \u2014 a practice known as MBD (Model Based Definition).<\/p>\n\n\n\n CAM is the software used by CNC machinists that converts the output from a CAD package \u2014 usually a 3D model \u2014 into a set of instructions for the CNC machine. These instructions are collectively called G-code<\/a>. Most professional CAD systems are designed to be integrated with built-in CAM tools to make the transition from CAD to CAM as seamless as possible. However, CAM functionality often does not come with the base software and must be purchased separately. These professional CAD systems do more than just 3D modeling<\/a>; they\u2019re full-fledged engineering tools.<\/p>\n\n\n\n SOLIDWORKS\u00ae<\/a> is CAD software developed by Dassault Systemes. It is an engineering tool that offers all the basic and advanced 3D modeling and 2D drafting features, plus additional functionality like finite element analysis, mechanism simulation, and product rendering. In terms of its use for CNC machining, Solidworks\u00ae 3D models can be exported to any CAM package. Solidworks\u00ae also supports model-based definition, and compatible CAM<\/a> software can be purchased at an additional cost. <\/p>\n\n\n\n Inventor\u00ae is Autodesk\u2019s product that competes with Solidworks\u00ae \u2014 it\u2019s comparable in terms of both basic and advanced features. Autodesk Inventor<\/a>\u00ae is especially useful for machine design as it has a large library of standard components. Another advantage of Inventor\u00ae is its tight integration with Autodesk’s other engineering programs like Autocad. However, Inventor\u00ae has a steeper learning curve than Solidworks\u00ae. It also has a standalone CAM<\/a> package that integrates seamlessly with the program, but must be purchased separately. <\/p>\n\n\n\n Fusion 360\u00ae is another 3D CAD software package developed by Autodesk. It was built as an all-encompassing engineering tool that covers the entire development cycle \u2014 from initial product design through evaluation stages and finishing with advanced CAM capabilities. It gives designers powerful simulation options that can test parts before finalizing designs. The seamless integration between CAD and CAM in Fusion 360\u00ae<\/a> is one of its key features, and it\u2019s one of the most intuitive CAD\/CAM software options available. However, some of the advanced CAM features in Fusion 360\u00ae are only available for an additional fee.<\/p>\n\n\n\n Most professional CAD packages have some CAM functionality, but they usually must be purchased separately. However, there are a number of highly capable standalone CAM packages with a range of advanced features. Here are some of the more popular standalone CAM packages: <\/p>\n\n\n\n MasterCAM has been the most popular paid CAM package for almost three decades. This popularity stems from its wide range of features such as: multi-axis milling and turning, an extensive list of preset CNC machine settings, and a flexible pricing structure. While MasterCAM<\/a> is tricky to learn, it\u2019s often an extremely powerful productivity-enhancing tool. MasterCAM does offer basic CAD functionality, but is less capable than dedicated CAD packages. <\/p>\n\n\n\n GibbsCAM<\/a> is a highly capable CAM package that includes features such as multi-task machining and highly accurate machine simulations. GibbsCAM can be used to generate basic 2D cutting paths as well as advanced 5-axis toolpaths. GibbsCAM<\/a> is generally easier to learn than MasterCAM, but its functionality is more limited.<\/p>\n\n\n\n Checkout Fictiv\u2019s CNC Machining capabilities<\/a><\/p>\n\n\n\n Listed below are some popular free CAD\/CAM software options. The free packages and free tiers of commercial software are not as powerful as the full-featured pro packages listed above.<\/p>\n\n\n\n FreeCAD is the only capable CAD package that is free to use with no strings attached. Other packages give you free access to basic functions, but their use is highly regulated and some features are locked behind paywalls. FreeCAD has an intuitive user interface and comes with a wide range of 3D modeling tools that make it ideal for designing CNC machined parts. FreeCAD<\/a> also has a CAM module that is limited to 2.5D milling. However, FreeCAD is far less capable than professional tools like Fusion 360\u00ae. <\/p>\n\n\n\n Autodesk offers a free version of Fusion 360\u00ae that gives users access to its core modeling features and can be successfully used to design parts for CNC machining. The free tier of Fusion 360\u00ae also comes with very limited CAM functionality, but cannot be used for commercial applications<\/a>.<\/p>\n\n\n\n Free CAM software is mostly limited because it can only perform a fraction of the complex tasks that are possible with professional CAM packages. In most cases, these free CAM programs can only generate G-code for 2D profiling or, at most, 2.5D milling, so they\u2019re often used in conjunction with CNC routers. Some typical packages are listed below:<\/p>\n\n\n\n This CAM software was developed for use with the Shapeko range of CNC routers. Its free version is limited to 2D profiling \u2014 only the paid version has a 3D contouring capability. When compared to professional CAM packages, Carbide Create<\/a> is limited and cannot meet the needs of industrial CNC applications. <\/p>\n\n\n\n This CAM software is web-based and has some limited CAD capabilities. It\u2019s primarily used for CNC routers and laser cutters and is limited to 2D profiling. Openbuilds CAM<\/a> is commonly used in artistic applications.<\/p>\n\n\n\n AutoCAD does not have built-in CAM functionality and, as such, its use for CNC is limited. However, AutoCAD is often used to develop 2D profiles for laser cutting, and most laser cutting facilities accept the Autocad DXF format. AutoCAD is primarily used to make technical 2D drawings and in rare cases, basic 3D models.<\/p>\n\n\n\n CNC machining is an expensive process, both in terms of initial capital investment and running costs. It doesn\u2019t make sense to use free tools to save costs when a single part failure during machining can easily eclipse the cost of a software package. If high-end CNC machines are used to cut expensive parts, best practice is to use industry-standard CAD and CAM packages such as SolidWorks\u00ae and MasterCAM. These two software packages are stable and have well-developed features. <\/p>\n\n\n\n Fusion 360\u00ae comes in at a close second and is, in fact, widely used in small to medium-sized machine shops. It is still in active development, so there is a risk that some features will not work as intended. However, Fusion 360\u00ae offers a smooth user experience and has a powerful set of features. <\/p>\n\n\n\n No matter which software you use, even the best designs benefit from expert DFM feedback and production partners who can bring those designs to life.
