Racing to the finish

In machining, many sacrifices are made in the pursuit of speed. Programmers who understand how to play on the edge of their performance envelope are rewarded with low cycle times and increased machine productivity. When it comes to determining the true cost of tooling performance, removal rates are often the only metric considered. Is this the correct way to approach your next job?

A customer approached us with a 4000 piece job. The deadline was short, and the hurdles were numerous. A simple 2 op part with some trouble features - notably the acute .125 radius corners. When running off the 1st article program with their current tooling and feedrates it became clear that the deadline was not possible. Worse yet the achieved finish was unacceptable.

We responded to a same day call to get tools in the machine. After setting up 2 Robbjack endmills we were able to make quick adjustments and had a set of fresh parts off the machine within an hour. The difference speaks for itself. Not only did we achieve a near 50% reduction in cycle time, but the finish is what sold my customer on our process.

He had resorted to tumbling the first parts to remove burrs from the old process which were no longer a problem with our approach.
