Computer Aided Manufacturing started being used by automotive and aerospace component manufacturing companies. This sped up the manufacturing process and thus increased efficiency ratings. However, the introduction of CAD into the industrial sector did not eliminate the need for skilled professionals.
In fact, the operation of this program requires a higher degree of skill in terms of being computer literate.
Flaws
The CAM system is a flawless solution. However speedy the system becomes, it still has faults that may hamper production. Since CAM generates a code for the least capable machine, an improperly set CAM software required heavy manual editing. In this case, editing such a code is a tedious and drawn-out process that takes a lot of time and effort (something that big-time companies cannot spare).
Another problem that you have to face is the data exchange that has to take place when integrating CAM with other components (CAD/CAM/CAE PLM). It becomes necessary for the CAM operator to export the data in a more compatible data format. And since the output stack of CAM is a G-code text file—sometimes containing thousands of commands—the operator is then faced with a very serious time problem.
CAM cannot reason. In this case, it cannot figure out the right toolpath for mass production. Operators would still have to select the type of tool to be used, the machining process that should be followed, and the path to be used. This means that the CAM cannot adjust to wear issues and sudden changes. It needs to be reprogrammed to be able to work efficiently. Furthermore, mass production increases the likelihood of errors to occur in the production cycle.
