More than 250 participants from 75 companies and organizations – mostly involved in the automotive industry – attended the Geometric Dimensioning and Tolerancing (GD&T) Workshop held at Lawrence Technological University in Southfield, MI, on March 27.
The workshop provided a working knowledge of GD&T, which is used on engineering drawings and solid models for describing nominal geometry and its allowable tolerances in product design, manufacturing, assemblies and inspections.
The workshop was led by LTU Assistant Professor Ahad Ali, director of LTU’s master’s degree program in industrial engineering. Ali is also the director of the Smart Manufacturing and Lean Systems Research Group, which organized the workshop in cooperation with the LTU student chapters of ASME, SAE, SME and Theta Tau.
Topics covered in the workshop included:
• Review of graphics in design and types of engineering drawings
• Fundamentals of orthogonal projection and sectioning
• Fundamentals of dimensioning
• Fundamentals of GD&T
• Tolerance stack-up analysis
• Statistical tolerancing
