# Building the future with CAM, Computer Aided Manufacturing Manufacturing any kind of product or machine used to be a long, intensive, imprecise, and complicated process that required input from a range of skilled craftspeople. Computer Aided Manufacturing (CAM) has revolutionized the means of production and given us the power to create precise, complex machinery and products. ## What is Computer Aided Manufacturing Software? As the name suggests, Computer Aided Manufacturing (CAM) involves **replacing human interaction in the manufacturing process with computer controlled machinery**. CAM allows us to create highly complex products quickly in a precisely uniform fashion. Before the invention of CAM techniques, skilled engineers and machine operators had to set up manufacturing machinery and operate it to create products. The machinery followed a set of punch card instructions called ‘jigs’ that engineers would manually put in place. Operators and engineers then needed to manually drive the machinery and ensure that it followed the instructions The entire process was error-laden, slow, imprecise, labor-intensive, and expensive. [CAM](/store/cad/2d-drawing-3d-model "How to transform a 2D drawing to a 3D model?") was a revolution in terms of how we manufacture goods and machinery. In essence, **CAM replaced the old-fashioned punch card jigs with a series of digital instructions which are sent to automated machinery via specialized software**. The machinery can then automatically cut material and assemble parts to produce products. [CAM](/store/cad/architect-vs-draftsman "How to recognize a draftsman from an architect?") **removes the possibility of human error**, **eliminates inconsistencies**, and reduces the number of prototypes required during the design process. The entire manufacturing industry has been made more efficient, more accurate, and cheaper using CAM. ## Discover the Computer Aided Manufacturing solutions from Dassault Systèmes Dassault Systèmes specializes in developing sophisticated CAM, CAD, and PLM software solutions that give designers, engineers, and manufacturers the power to reimagine and reinvent how they create and produce. ![](https://www.3ds.com/assets/invest/2024-06/solidworks-cloud-offer-cad-design.png) ![Solidworks cloud offer](https://www.3ds.com/assets/invest/inline-images/logosolidworks.jpg)### [**SOLIDWORKS xDesign**](/store/solidworks-xdesign "SOLIDWORKS xDesign: Cloud Native Cad, From Any Browser, on Any Device") Get ready for the next generation of design solution, developed by the same team that brought you SOLIDWORKS 3D CAD [Discover SOLIDWORKS xDesign](/store/solidworks-xdesign "SOLIDWORKS xDesign: Cloud Native Cad, From Any Browser, on Any Device") View details ![](https://www.3ds.com/assets/invest/2025-11/catia_essential_card.jpg) ![CATIA ](https://www.3ds.com/assets/invest/inline-images/logocatia.jpg)[**PLM Express Design Engineering**](/store/plm-express-design-engineering "Professional CATIA Bundles: AI-Driven Design Engineering, Ready to Use") Empower smart product design and boost **engineering precision** [View product](/store/plm-express-design-engineering "Professional CATIA Bundles: AI-Driven Design Engineering, Ready to Use") View details [ Lean management software ](/store/lean-team-player) ![](https://www.3ds.com/assets/invest/2024-06/lean-team-player-de-mng.png) ![Delmia Lean Team Player](https://www.3ds.com/assets/invest/inline-images/logodelmia.jpg)### [**DELMIA Lean Team Player**](https://www.3ds.com/store/lean-team-player) Make collaboration effective, intuitive and easy with a cloud-based whiteboard designed to fuel innovation [**Discover Lean Team Player**](https://www.3ds.com/store/lean-team-player) View details ![](https://www.3ds.com/assets/invest/2024-06/3dexperience-solidworks-cad.png) ![Solidworks cloud offer](https://www.3ds.com/assets/invest/inline-images/logosolidworks.jpg)### **SOLIDWORKS Design** From mechanical 2D or 3D design to manufacturing, accelerate your processes at an affordable price.

The CAM process is made up of various stages, each of which is intrinsic to the outcome. Each stage needs to be carefully planned and executed in order to avoid production mistakes that can result in manufacturing errors and product defects. ### The design stage The CAM process begins with a designer or engineer **developing a detailed 3D digital model** that represents a proposed product or machine. The 3D model is constructed using specialized computer aided design ([CAD](/store/cad "Why Computer-Aided Design Is a Game-Changer for Engineers")) software, subjected to various tests and simulations and refinements are made. ## The design stage [![CAM : the design stage > Dassault Systèmes](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing_0.jpg)](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing_0.jpg) ## The post-processing stage [![The post-processing stage > Dassault Systèmes](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing3.jpg)](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing3.jpg) ### The post-processing stage Although CAM machines perform automated functions, they are not entirely autonomous. They require a set of instructions to follow. After the design has been finalized, CAM software checks the model to see if it has any errors that will impede manufacturing and then generates a **toolpath that the CAM machinery uses to create the product**. These toolpath instructions are known as **Computerized Numerical Control (CNC)**. CNC uses a machine language known as **G-code**. **G-code controls a machine’s speed**, its **actions**, the **feed rate**, as well as any coolants it requires, and so on. This is known as the post-processing stage. ### The machine simulation stage Before manufacturing commences, a machine simulation is run. This simulation is a **digital representation of all aspects of the CAM process**. It allows engineers to develop the most efficient method of producing a product and can be used for [mechanical design](/store/plm-express-design-engineering "Professional CATIA Bundles: AI-Driven Design Engineering, Ready to Use"). ## The machine simulation stage [![The machine simulation stage > Dassault Systèmes](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing2.jpg)](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing2.jpg) ## The manufacturing stage [![CAM : The manufacturing stage > Dassault Systèmes](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing4_0.jpg)](https://www.3ds.com/assets/invest/2023-04/computer-aided-manufacturing4_0.jpg) ### The manufacturing stage After the optimum manufacturing method has been identified, the actual process of manufacturing can begin. The CNC code is transmitted to the machinery via CAM software, raw materials are fed to the machinery, and the manufacturing process itself begins. **Engineers will closely monitor the initial manufacturing run to identify any errors or defects**. Rigorous quality control checks are required for each step of the process as well as on the final product. ## What are the different types of CAM software? As there are different stages of the CAM process, not all CAM software is designed for the same purpose. [Engineers](/store/cad/engineering-drawing "Engineering drawing explained, why is it a crucial design skill?") can make use of selected types of CAM software for specific roles. Some of the most common types of CAM software include: ## CAD/CAM Software Generalized dual-purpose software used for the design and manufacturing of products and prototypes. ## CAM Analysis Software Also known as computer aided analysis software (CAA), these programs help engineers to identify errors in the CAM process. ## CAM Simulation Software Creates machine simulations that are used to analyze the manufacturing process. ## CAM Optimization Software Optimization software analyzes CAM toolpaths to generate the most efficient method of creating a product. ## CAM Nesting Software Nesting is a cutting process used by CNC machines. Nesting software controls machines such as waterjet cutters and laser cutters. ## CAM Lathe Software Lathes turn workpieces on their axis at high speeds to perform cutting, sanding, polishing, or drilling actions. CAM lathe software provides information to specialized CNC lathe machinery. ## CAM Milling Software Milling in manufacturing refers to the action of using rotary cutting tools to remove material from a workpiece. CAM milling software is used to control these machines. ## Browse all the Dassault Systèmes store applications We feature in our [store](https://www.3ds.com/store/) some of our best software to design, collaborate and innovate throughout the entire product lifecycle.
