The 11 Principles of Precision Machine Design

The 11 Principles of Precision Machine Design

The 11 Principles of Precision Machine Design were developed at CUPE - Cranfield Unit for Precision Engineering which ultimately evolved into Cranfield Precision. Development of the 11 Principles of Precision Machine Design and CUPE were lead by Professor Pat McKeown.

Cranfield Precision are world renowned for their expertise in designing and developing special purpose machines. Many new and existing world leading precision machine tools are still based on the 11 Principles of Machine Design which Cranfield Precision still utilise today.

The 11 Principles of Precision Machine Design

• 1. Structure
• 2. Kinematic / Semi Kinematic Design
• 3. Abbe Principle
• 4. Direct Displacement Transducers
• 5. Metrology Frames
• 6. Bearings
• 7. Drives / Carriages
• 8. Thermal Effects
• 9. Servo-Drives and Control (CNC)
• 10. Error Budgeting
• 11. Error Compensation

Cranfield Precision has developed and improved upon each of these key principles and has also developed many new technologies that embody and advance these principles.
