There are a couple of articles in Machine Design and Control Engineering on a company using Galil’s DMC-21×3 series of motion controllers to control a five-axis waterjet cutter for carpet and astroturf materials. The machine is unique because it allows bevel cuts with angles up to 45°.
The Galil DMC-2153 controller takes commands from a CNC front-end running on a PC and handles tracing out the pattern with an XY gantry, water jet height, keeping the water stream tangent to the cut. The Galil controller provides smooth motion by applying linear and circular interpolation to a stream of commands sent every 4 ms by the PC.
