6 Difference between CAD and CAM (With Table)

The dynamics in designing and manufacturing have been spearhead by CAD and CAM. These applications are essential tools for designing and manufacturing. 

These applications can help to design shapes in two and three-dimension respectively. The revolution in animation programs and engineer drawings relies on this software.

So, what is the difference between CAD and CAM? The former is an application that entails the use of computers to transform the elementary idea of product into engineering designs whereas the latter also uses computers to help managers in planning and controlling activities in a manufacturing plant. 

This article provides further differences between CAD and CAM in a tabular form. Take the time to also find out the relationship between CAD and CAM.

What is CAD?

CAD is mainly the use of a computer to design a simple language. The abbreviation stands for computer-aided designs.

CAD usually entails the use of a good number of tools to help the engineers and architects undertake their work of designing professionally.

CAD is normally used in case the simple drafting cannot address the issue and it is highly applicable in airplanes, ships, and automobiles.

Advantages of CAD

  1. Reduce the use of huge numbers which tend to be expensive
  2. Help to generate cutting data for CNC machines
  3. Offer accurate and automatic modifications in drawings and models
  4. Retrieval and storage of models is easier
  5. Increase the rate of production at a low cost
  6. Multiple copies can be stored, shared, and printed

Disadvantages of CAD

  1. Prone to power cuts and computer viruses attack
  2. The initial cost for the startup is too high
  3. Training is expensive and time-consuming

What is CAM?

CAM is a computer-based tool that helps to manufacture and prototyping product components. The abbreviation stands for computer-aided manufacturing.

Besides that, CAM is a computer design system that helps in planning, managing, and controlling activities in a manufacturing plant.

Advantages of CAM

  1. The process is faster and more efficient
  2. Reduce wastage of raw materials due to minimal errors
  3. Save on labor cost since it is less labor-intensive

Disadvantages of CAM

  1. Initial investment and startup cost is too high
  2. The maintenance cost of machines is expensive
  3. Causes unemployment since it discourages manual skills
  4. Need a high level of training which is costly

Main Differences Between CAD and CAM 

  1. CAD is the use of a computer for transforming an elementary idea into product design while CAM is the use of a computer to assist managers or engineers to automate tasks.
  2. CAD uses software such as CATIA, Autodesk Inventor, and AutoCAD while CAM uses SolidCAM, workNC, Power Mill, and Siemens NX.
  3. CAD requires conceptualization and analysis while CAM relies on control and coordination of physical process, labor, material, and equipment.
  4. The geometric modeling used in CAD is an interface, drafting, analysis algorithm, documentation, and detailing while CAM uses numerical control programs, inspection, assembly, and process planning.
  5. CAM has processes that are quite faster and accurate, unlike CAD which is prone to errors.
  6. Retrieval and storage of models in CAD are quite easier as compared to CAM.

Frequently Asked Questions

  • Is a 3D Printer CAD or CAM?

3D printing is the process of making solid objects in three dimensions from a digital file. Therefore, both CAD and CAM are used for machining prototypes and finished parts.

  • What is the relationship between CAD and CAM?

The applications are used to design a product and program manufacturing processes. CAM software uses the models and assemblies created in CAD software to generate tool paths that drive machine tools to turn designs into physical parts.

  • What Does CAD Stand for in 3D Printing?

Computer-aided design. It is typically used to generate virtual 2D or 3D models.

  • Why is CAD Important in Manufacturing?

It allows for the easier development of products and product management integration. It also allows for greater modeling and even provides a basis for virtual networking.
