Do you ever feel like you know just enough about CNC to be dangerous? Let’s see if we can fill in some of the gaps with the latest info from CNC experts.

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.

If you find yourself confused by what you’ve read to this point, don’t despair. Everything should be crystal clear by the time you finish.

PROS

CAM can cut cycle time significantly. This means that with the proper people and the proper tools, a more efficient production method can be obtained. A lower cycle time means that you can produce more components in a lesser time. And since the main users of CAM and CNC are big manufacturers with deadlines, it is of the utmost priority to cut cycle time.

Another advantage that could be gained by CAM software is the increase in machine life. Since the process is automated, the system can keep track of certain variables that allow it to adjust to the conditions of the machine that is operating under it. This means that the life of the machine can be extended by adjusting the performance of the machine in order to avoid overworking it.

Quality can also be taken into account in this scenario. It is because the system also monitors slight differences in the production environment. Furthermore, the intricate designs that cannot be achieved by human engineers can be achieved by the machines. Also, these designs can be completed at a faster rate compared to manual operations. Another factor that should be considered would be the error ratio of the production of any components.

Conclusion

So, CAM is a very important aspect of production. However, the need for skilled operators still exists as programming and setting up these machines decide the fate of the manufacturing process. However, the increased automation and efficiency provided by such a system makes programming and setting up of these systems the only jobs of the operators.

This also allows operators to be more productive as they do not have to watch any single machine for more than the required amount of time.
