To ensure that your designed part fulfills its application needs, the CAD software also allows you to simulate how your parts can be machined before the process begins. So, identifying mistakes and making corrections in specific areas is easy. The software’s design interface allows you to have a perfect view of different parts of the design. The models can either be 3D, 2D or 2.5D depending on your chosen software solution. Let’s find out The Role of CAD Softwareīelow are the main uses of CAD software in the CAD/CAM software package: CAD Software – Designing or Modeling PartsĬAD software allows you to design or create component models based on your project needs. The two integrated software have their specific roles. CAD & CAM Software for CNC – What Are Their Roles?ĬAD/CAM software for CNC machines comes as a package. In general, your production efficiency will also be significantly enhanced. You then use the model parameters to program your CNC machine to automate your production process.īecause CAD/CAM software helps in the simulation of the machining process, your production of parts will have low risks of errors. The software allows you to come up with different models of parts depending on your requirements. It allows you to create parts designs faster and precisely while cutting labor costs. The main reason for investing in a suitable CAD/CAM solution is to enhance your manufacturing efficiency. Why Do You Require CAD/CAM Software for Your CNC Machines? It is equipped with tools that make the process much quicker and with high precision.Īfter the design or modeling state, you can use the precise dimensions to create programs that your CNC machines and tools can then use to produce the desired parts. This software package allows you to create a two-dimensional technical drawing, plan, or draft of the component you want to design or produce. It is used in situations where you need to cut several flat sections of your component but at different cutting depths. You do this by moving it in a 3-dimensional space to create a 3D illusion!Ģ.5D designs are necessary if you have 3-axis CNC machines. It allows you to create your 2D model and then make it appear as if it is a 3D model. This is a hybrid modeling or design software that borrows from both 2D and 3D features. This is possible because you can have a perfect representation of the part before its production. With the 3D CAD/CAM software solution, it is easy to correct errors in your design before it is physically manufactured. The 3D package enables you to generate commands that your CNC machine can use to either create or machine your components.Īfter creating a suitable 3D design, you can produce the part using a suitable CNC machine tool. This is computer-aided design (CAD) software that you use to create 3-dimension part designs or models. Some packages come as a combination of these three categories. CAD/CAM Software – 3 Main Modeling/Design OptionsĬAD/CAM software packages come in three main design categories namely 3D, 2.5D, and 2D.

Its invention was through the collaboration of Richard Kegg and the Massachusetts Institute of Technology. However, it was in the 1940s that the first CNC milling machine came to life. It is interesting to note that the machining principle that CNC machines use goes back to the 18th century. Historical Background of CNC Milling Machines Therefore to facilitate both the design and the production processes of your CNC machine and tools, the two software solutions come as a single or integrated package. So, it helps you program CNC machines to facilitate the production or machining of your designed parts. Therefore, it helps you to design or model the parts you intend to produce.ĬAM stands for Computer-Aided Manufacturing application. 11 Conclusion Distinguishing CAD and CAM Software for CNC ProductionĬAD is an acronym for Computed-Aided Design software.
