CAD/CAM Q&A: General Industry Coverage

Having the proper CAD/CAM system is critical when machining parts. Presented here are the answers to 10 key questions about how to determine the right CAD/CAM system for your operation.

1. What should I look for in a CAD/CAM system when considering lights-out machining?

The system must reliably output NC data on nonproduction parts, such as tooling and prototypes. Many software developers make that claim, but care should be taken in evaluating if the system can provide reliable toolpaths, machining simulation, automatic tool changes, laser calls to validate tool wear and automatic selection of sister, or backup, tools.

A CAD/CAM system should provide virtual machining, or machine simulation, for planning, testing and optimizing toolpaths. All images courtesy Tebis America.

2. Can all CAD/CAM systems handle large data sets?

“Large” means physical part size or the number of bytes the file occupies on a computer. Not all CAD/CAM systems effectively handle these types of files. The system should be able to handle them in both the CAD and CAM sides. It makes no sense to have separate CAD and CAM systems because your files are too big.

Implement 3+2 roughing with 3D stock model for machining steep and undercut areas.

3. Do I really need powerful machining strategies in a CAM system?

Many systems use the same naming conventions but their output results vary. Having real “high-end” strategies enables optimal machining times, long tool life and fine surface finishes with less user effort.

4. How important is it for the CAD/CAM team to fully explore all software functions?

While majority of users do not fully explore all functions available in their systems, training users on the latest functions in new releases is an excellent investment. Many software developers provide technical information and tips and tricks through webinars, newsletters and training videos. Motivate your CAD/CAM team to make use of these tools.

5. Should I consolidate the different CAD/CAM systems in my shop?
