Level 3 :Advanced GD&T

Course Length: 2 Days (16-hours)

Course Format: Instructor Led

Course Objective:

To provide applied working knowledge of Advanced GD&T applications involving optimization strategies for given design applications, manufacturing methodologies and measurement planning. 

Course Content:  

• MMB, LMB and RFB applied to datum features of size 
• Multiple feature patterns used to define a single datum, and negative implications of using “non-functional” surfaces as datum features 
• 3D analysis of composite position callouts, in relationship to multiple-hole pattern defined as a single datum 
• Calculations for determining allowable position tolerance for floating and fixed fastener designs 
• Positioning holes and pattern of holes at “zero tolerance” for optimizing manufacturability and critical cost reductions 
• Positioning coaxial cylinders from independent datum features -vs- to each other and defined as compound datum features 
• Boundary principles used with profile for non-cylindrical shapes 
• Mathematical definitions and implications of ASME Y14.5.1M-1994 
• Surface roughness implications to features of size and form constraints  
• Analysis and discussion of common error implications of dimensioning and tolerancing of tooling and functional gaging, based on product designs 
• Evaluate negative implications of common incorrect measurement procedures on coordinate measuring machines and discuss procedures to resolve / minimize problems 
• Review and analyze engineering drawings and identify areas of negative financial implications, address questions to provide clarification/direction and make recommendations to optimize design intent and achieve maximum return on investment 

Target Audience:   Anyone requiring a greater understanding of GD&T from an advanced applications perspective. Engineers, designers, metrologists, technicians, machinists, toolmakers, senior inspectors, senior technicians, statisticians and mechanical engineers at all levels will benefit from the advanced applications in this course. 

Prerequisites: Introductory GD&T or equivalent knowledge.
