Selecting a new computer-aided manufacturing (CAM) system is a strategic decision that influences productivity, flexibility, and competitiveness. While the process can seem daunting, especially when moving away from familiar systems, addressing key considerations can help determine the benefits.
It can be helpful to consider several criteria, including the advantages that modern CAD/CAM solutions offer to shorten part programming time and increasing the productivity of your CNC machines
Adopting a Holistic View
When determining what you need in a CAM system, don’t limit the analysis to what your current CAM system is providing. Instead, include all aspects of production.
- In addition to milling and turning machines, include production processes such as wire cutting or laser cutting machines
- Consider the materials you use and what challenges you may be facing when cutting these materials
- Think of areas in your current design and manufacturing processes where there may be bottlenecks or areas where efficiency can be improved
- Assess communication between CAD, CAM, CAE, and PDM systems
- Identify areas where you are experiencing challenges or frustrations
- Evaluate where modern technologies can assist your company transformation objectives
Prioritizing Profitable Transformation
Transformation inherently implies change—and in manufacturing, this change affects both people and processes. Focusing only on current capabilities can hinder objective assessment and long-term potential. Evaluate systems that provide you with the following benefits:
- Technologies that reduce programming time
- Optimal balance of automation and control
- Ability to save your programming preferences and re-use them
- Machining strategies that improve productivity
- Intelligent processes that save time and reduce human error
Avoiding Common Pitfalls
During the consideration of implementing a new CAM system, avoid some of the thought processes that can be counterproductive.
A common misconception during system evaluations is the belief that a new solution must outperform the current one in every possible way. This expectation potentially eliminates systems that offer valuable strategic advantages despite minor trade-offs.
There is also a danger in assuming that the current system is sufficient, or that a transition will be too difficult for your team to adopt. This assumption unnecessarily limits the selection based on individual habits instead of evidence.
Achieving More with Modern CAM Technologies
Below are some of the technologies that today’s CAM systems provide to advance manufacturing.
Seamless CAD/CAM Integration
Fully integrated CAD/CAM is a natural progression in manufacturing advancement. Outdated systems that require importing and exporting of part files between a CAD and CAM system unnecessarily introduce data exchange issues and complications. With a fully integrated system, all the part data is stored in a single file.
Full Associativity between Design and Machining
With modern CAM systems that are fully embedded in CAD programs, any time a design change is made to a part, the manufacturing data such as toolpaths and G-code are automatically updated. This saves time spent on trying to determine which iteration of a part is correct and saves material with the assurance that the latest version of the part is the one being machined.
Automate Repetitive Processes
Significant amounts of time can be saved in part programming when repetitive processes are automated. Modern CAM systems automate tool path generation, automatically transfer component information (tolerance-based), and use optimized machining strategies with preferred tool selection, cutting speeds, and feed rates based on material and component. These systems accelerate and make CNC programming more efficient. In addition, the best programming practices of your company and your team’s programming preferences can be saved for reuse in future parts, saving more time when programming subsequent parts.
Future Proofing Your Investment
Just as your company makes changes for advancement, CAM systems and their manufacturers are also subject to transformation and advancement. In addition to assessing a CAM system’s use of the latest technological technologies, it is also beneficial to give attention to the CAM company’s policies on regular updates, technical support, development potential, complimentary product offerings, and the economic situation in general.
Adopting a new CAM system isn’t just a technical upgrade—it’s an organizational transformation. A modern, integrated solution will impact design, manufacturing, and competitiveness across your business. Success depends on a thorough and unbiased evaluation process, clear communication among stakeholders, and a focus on long-term productivity and adaptability. By addressing both technical and cultural aspects, your company can position itself for a smarter, more efficient future in manufacturing.
