INTRODUCTION FOR GEOMETRICAL PRODUCT SPECIFICATION – ISO 8015
Geometric product specification (GPS) is a language used on mechanical engineering drawings composed of symbols that are used to efficiently and accurately communicate geometry requirements for associated features on components and assemblies. GPS is, and has been, successfully used for many years in the automotive, aerospace, electronic and the commercial design and manufacturing industries.
Success oriented industries and organizations which, require accurate and common lines of communications between engineering, design, manufacturing and quality should consider GPS as their mechanical drawing standard.
COURSE OBJECTIVES
At the conclusion of this 2 days program, participants will be able to:
- Gain knowledge on what GPS is all about
- Explain the benefits of geometric tolerancing
- Learn how to apply GPS in their job
- Able to interpret customers requirements from the design drawing
- Be reminded of the Do’s & Dont’s of proper tolerancing
- Able to set quality control criteria from design drawing
- Identify datum features and determine their order of precedence
- Identify and interpret each of the characteristic symbols
- Correctly interpret GPS feature control frames, and explain the impact on manufacturing and inspection
WHO MUST ATTEND
- This 2 day’s workshops has been designed for Engineers, Supervisors, Technicians, Inspection & Measurement Technicians and Production staff who are involved in design, measurement and production of mechanical parts.
- This course is designed for personnel whose work requires them to communicate, interpret or manufacture products through the use of engineering drawings and/or CAD
- Also those communicating constantly with customers for new parts/molds manufacturing.
- Participants should have an understanding of basic blueprint reading.
METHODOLOGY
- The workshop is a mixture of presentation with personal examples, videos, assessment, discussions and group activities.
- Practical activity on drawing interpretation and measurement methods will be given throughout the training for better understanding.
DURATION
2 days
