The key problem to be addressed in Phase I of this project will be to determine the feasibility of a novel position measuring system for a family of computer controlled machine tools. The multiple laser measurement system (MLMS), which forms the basis of this proposal, will measure the (x, y, z) position of the cutting head directly at rates and accuracies sufficient for closed loop position control. Questions about the ability of MLMS to operate on a factory floor can only be answered by developing the concept as part of a machine tool which will be sold and supported. In this context, the system must satisfy criteria of reliability, cost, ease of operation, and reparability. Apeiron's partnership with Komo Machine, Inc. assures that these criteria will be addressed.
