This tutorial provides a fast-paced hands-on introduction to rapid precision machine design based on FUNdaMENTAL principles including theory and best practices. Topics include: initial error allocation to enable rapid design, principles of accuracy, repeatability and resolution, bearings, structures, and actuators. Kinematic and elastic averaging-based designs and the implications for bearing life and dynamic performance are stressed with F=kx and w = sqrt(k/m) as recurring themes throughout the design of a machine. Examples will be presented to show how FUNdaMENTAL principles are critically important for an engineer to understand in order to be able to most effectively use modern design tools such as solid modelling and finite element analysis in the design of precision machines.
This tutorial should be helpful for those at the beginning of their careers and also for those who wish to tune up their design approach with linking design approaches with first order analysis to develop designs more rapidly and to check output from FEA.
Attendees should expect to leave with new design tools (spreadsheets) they feel comfortable applying and a host of new design ideas for selecting and integrating bearings structures and actuators in precision machines.
