Miceli Technologies offers the constant velocity controller (CVC), a CNC incorporating a new approach to toolpath algorithms that produces a processing speed of 50,000 blocks per second. According to the company, this enables fast, constant feed rates for machining complex geometries. In contrast, CNCs with lower block-read speeds might not be able to consistently push machines at programmed feed rates. The resulting inconsistent tool motion can load flutes differently, adversely affecting accuracy and surface finish, and can shorten tool life by not moving the cutter fast enough to maintain minimum chip load, causing it to rub rather than cut.
Smooth, constant tool movement can result in less wear, better finishes, longer cutter life and faster cycle times, so retrofitting the CVC can be an economical alternative to purchasing a new machine tool, the company says. Capable of interpolating as many as eight axes, the control features 80 high speed buffers to control and monitor tool motion, 4 million maximum (servomotor) encoder counts per second, 15-digit motion control accuracy and a minimum resolution of 0.001 micron.

Connecting machines to a network for production monitoring almost guarantees that utilization will go up, but that’s only the first step toward data-driven manufacturing.
