Summary
Saginaw Machine Systems Inc.'s Real Time Error Correction system
Saginaw Machine Systems Inc. has devised a production system that corrects both geometric and thermal errors on a variety of two-axis and three-axis machine tool types. The PC-based Real Time Error Correction System eliminates 80% of a machine tool's errors while enhancing accuracy. The project focuses on three objectives, namely: to include all thermal and geometric error components in one synthesis model, to make the method valid for most types of machine tools and to provide suitability for different measuring positions due to different measurement methods and instruments.See the full content of this document

Correcting for thermal expansion in real time.
The search for machining's Holy Grail--real time compensation of thermal expansion--is going on in earnest at Saginaw Machine Systems Inc. A series of three research and development projects has already demonstrated improvements in machine tool accuracy by a factor of four to five times, improving the overall accuracy of the workpieces the machines produce.
It is a manufacturing axiom: Today's highest levels of precision are good, but closer would be better. There is a never-ending effort to close (or at least to narrow) t...See the full content of this document
