Introduction to Computer aided Manufacturing (CAM) | Advantages Of CAM

Computer-aided manufacturing CAM also known as Computer-aided Modeling or Computer-aided Machining [1] [2] [3] is the use of software to control machine tools and related ones in the manufacturing of workpieces. CAM leverages both the value of the most skilled manufacturing professionals through advanced productivity tools, while building the skills of new professionals through visualization, simulation and optimization tools. Historically, CAM software was seen to have several shortcomings that necessitated an overly high level of involvement by skilled CNC machinists.


Fallows created the first CAD software but this had severe shortcomings and was promptly taken back into the developing stage. In some cases, such as improperly set up CAM software or specific tools, the CNC machine required manual editing before the program will run properly. None of these issues were so insurmountable that a thoughtful engineer or skilled machine operator could not overcome for prototyping or small production runs; G-Code is a simple language.

In high production or high precision shops, a different set of problems were encountered where an experienced CNC machinist must both hand-code programs and run CAM software.

What is Computer Aided Manufacturing (CAM)?

CAM packages could not, and still cannot, reason as a machinist can. They could not optimize toolpaths to the extent required of mass production. Users would select the type of tool, machining process and paths to be used. While an engineer may have a working knowledge of G-code programming, small optimization and wear issues compound over time.

CAM – Computer Aided Manufacturing

Mass-produced items that require machining are often initially created through casting or some other non-machine method. This enables hand-written, short, and highly optimized G-code that could not be produced in a CAM package. At least in the United States, there is a shortage of young, skilled machinists entering the workforce able to perform at the extremes of manufacturing; high precision and mass production.

Over time, the historical shortcomings of CAM are being attenuated, both by providers of niche solutions and by providers of high-end solutions.

1. Basic introduction

This is occurring primarily in three arenas:. Most machining progresses through many stages, [15] each of which is implemented by a variety of basic and sophisticated strategies, depending on the part design, material, and software available. From Wikipedia, the free encyclopedia.
