Course Objectives
This course is to give the basic precision engineering methodology and state-of-the-art concepts for designing high-precision CNC machines and products. The course is specifically tailored to teach the novel design principles leading to improved machine performance and reliability. Even though the course will mainly focus on the design of high precision CNC machining centers and coordinate measuring machines (CMMs), the student could easily apply the acquired knowledge to other design efforts and fields as well.
Course Content
Introduction, analysis/principles/techniques for designing high-precision machines, Abbe and Bryan principles (or options), geometric/thermal error budgeting, thermal effects, machine structures, design of bearing systems/guideways/spindles, measurement systems, machine metrology, electromagnetic actuators and drive systems, high-precision motion control systems, error compensation techniques, advanced interpolator design, machine testing, advanced concepts in precision engineering.
Course Learning Outcomes
Student, who passed the course satisfactorily, will be able to:
-
explain / distinguish the meanings of fundamental terms such as accuracy, repeatability, precision, and Abbe offset error;
-
apply the concept of error budgeting as a design tool;
- develop advanced kinematic models of precision machines and systems;
-
select appropriate materials and components to develop a precision machine (or instrument) considering tradeoffs in performance, cost, manufacturability, etc.;
- design effectively precision machines and mechanisms.
