As the demand for more sophisticated and efficient machining increases, so does the need for more sophisticated computer aided manufacturing/machining (CAM) software. Software that can reduce machining time significantly can increase machining productivity and profitability in the same way, and in today's CNC-driven world, the right CAM software can be the difference between surviving and thriving. However, if a shop manager considers only machining efficiency in selecting CAM software, he may be missing other profitmaking opportunities.
There are more than 40 CAM software packages on the market today. Chances are that no matter how complex the machining requirements there are at least three or four packages, often many more that will do the job in a reasonable amount of time.
There are several packages for every type and for every level of machining from entry level general machining to 5-axis, simultaneous multi-spindle, multi-tasking operations.
The decision on which CAM package to buy usually depends on what the shopÕs personnel currently use, and what the machine tool distributor recommends. Too often, not enough consideration is given to how the software - and, especially, the part model used by the software - fits in with other shop requirements.
That's where potential profit gets lost.
Consider the part model that's used to drive the CAM software. Where did it come from, and where can it be used besides generating G-code?
In the best of all worlds, the part model created by the original designer is used directly throughout the entire manufacturing process. If communication between the designer and the customer uses the same part model, then the chance of miscommunication and incorrect or overlooked changes is reduced.
The same is true between the designer and the machine shop, between the machine shop and its suppliers, between the customer and its sales forces, and ultimately between the customer and their customers.
