- Quality Tools & Techniques
- 21 hours
Introduction:
This course is designed for experienced practitioners with deep knowledge in GD&T and want to deepen their skills in the specialized area of tolerance stack.
Objectives
Manufacturing organisation deploys a systematic flow of information to translate customer requirements into the Product Realization.
Learners will be able to further advance their skills, knowledge and application of GD&T which involves Design Tolerance Stack-up analysis and calculation using worst-case analysis method to evaluate the accumulation effect of parts and assembly requirements.
These skills and knowledge are vital in the Product Realisation, Measurement, Analysis and Improvement and in the Quality Management System consisting of Product Requirements,
DFMEA, Mechanical Fit and Mechanical Performance Requirements and Acceptance Criteria to prevent part and assembly failure and to improve manufacturing efficiency.
Duration
3 days | 9am ~ 5pm | 21 hours
Who Should Attend
Design, Quality, Manufacturing Engineers and professionals that need involved in mechanical design, product development and quality assurance.
Course Fees
Member Fee: $1,600.77
Non-Member Fee: $1,776.70
All fees stated are inclusive of Registration Fee and 9% GST.
Award of Certificate
Certificate of Completion will be issued to participants who have attended at least 75% of the course.
