CAM and CAD programming is used to convert computer-aided design (CAD) into details produced by manufacturing support software (CAM) on CNC machines. Many companies on the market provide CAD/CAM software tools for various CNC programming needs, from basic to very complex. It is easy to find suitable services and applications that promote innovative, flexible solutions and best-in-class support networks. As in practically every industry nowadays, you can buy just the software, or you can add full service, technical support, and additional packages. Why might CAM programs seem attractive? Is computer-aided manufacturing the future for CNC? What is the CAM program about? You will find the answers to these questions in our article!
CAD CAM software package for beginners
What you are looking for is the simplest basic software package for CAD/CAM workflow. The following types of software will be needed for this:
- CAD - stands for Computer Aided Design. CAD software is used for drawing on a computer, but measurements are marked on the drawing. It is used for creating and improving designs. Moreover, it also allows for creating "plans" for parts in CNC machining.
- CAM – stands for Computer Aided Manufacturing. All you need is a CAD drawing file to use extensive instructions and consequently create a g-code based on this information. In other words, g-code is a set of commands for a CNC machine on how it should process the material.
- Feed and speed calculators – some CAM packages have limited feeds and speeds, which can be quite troublesome. In general industry research and surveys, such limitations were among the main complaints about CAM software. Beginners need as much help as possible to avoid damaging the tool, hence it is understandable that a good feed and speed calculator will make the job easier.
- Control software: it is usually embedded in the CNC machine, so we only present a basic overview of information.
Depending on the needs of the enterprise, it is worth paying attention to what we really expect from CAD/CAM software not only based on the current processes we handle, but also in terms of the somewhat predictable future. If we expect dynamic development of the company, it will certainly be sensible to choose an application beyond the current state. Hopefully, this article will be of help to you.
CAM Software vs CAD - Differences
CAD stands for computer-aided design. Like CAM, CAD uses computational power and software to assist designers in creating more complex and advanced designs and provides the ability to produce complex components that would be difficult to do manually. The difference between CAD and CAM is that CAD helps designers create digital representations called 3D models, while CAM systems assist in writing code to control CNC machines, which in turn create physical parts.
Why is computer-aided manufacturing important?
CAM unlocks a wealth of automation and powerful capabilities that simply aren't possible with conversational or manual NC code. High-performance roughing tool paths utilize algorithms that require computer calculations. Manually creating tool paths with complex geometry is almost impossible, hence CAM software is a necessity.
Computer-Aided Manufacturing Applications
Many packages offered by IT companies include a complete set of CAM tools and toolpaths to handle various processes, including milling, turning, cutting, and additive manufacturing. Additionally, they integrate CAD, engineering, documentation, and collaboration tools directly with CAM to streamline workflow and take over the entire product development process.
In which industries is computer-aided manufacturing CAM used?
- Automotive:
From high-strength machined parts to molds used for the production of fiberglass coatings for various car bodies.
- Industry:
CAM software is widely used in industrial machines, whether it's for sheet metal fabrication or casting with tolerance maintenance.
- Biotechnology:
Both additive and subtractive manufacturing are used for the production of dental implants, prosthetics, and even joint replacement parts.
- Aviation:
The aviation industry requires CAM to produce parts with high durability and narrow tolerances, where it is common in the machining of aluminum and titanium alloys.
Benefits of CAD
- Using CAD design tools can provide engineers and designers with significant benefits compared to traditional techniques and manual drawing,
- Reducing the project production costs,
- Fluid workflow and design process to accelerate project realization,
- Changes can be made independently of other details without completely redoing the sketch,
- Higher quality elements with built-in documentation (e.g. angles, measurements, preset settings) in the file,
- More transparent projects, better readability and easier interpretation by colleagues, as hand drawings are not clear and detailed enough,
- Using digital files facilitates collaboration with colleagues (easier sharing, storage, and division),
- Software capabilities can support generative design, solid modeling, and other technical possibilities.
CAD Software and Tools
There are many CAD tools that assist designers and engineers. Some CAD applications are tailored to specific use cases and industries, such as industrial design or architecture. Other CAD software solutions are available that support various fields and types of projects. Some commonly used CAD tools include:
- MicroStation (offered by Bentley Systems),
- AutoCAD (offered by Autodesk),
- CorelCAD,
- IronCAD,
- CADTalk,
- SolidWorks,
- Onshape,
- Catia,
- LibreCAD,
- OpenSCAD,
- Vectorworks,
- Altium.
Remember that a properly selected program and configured CNC machine improve many machining parameters and reduce tool load. The machining parameters and the machining process itself in CAM systems will certainly become more enjoyable and accurate than in the traditional form. Therefore, use the CAM system and the instructions and rules described in detail on our website, and your CNC product will be perfect.
