MT 267 - Dimensioning and Tolerancing

2 lecture hours 2 lab hours 3 credits
Course Description
This course is an introduction to Geometric Dimensioning and Tolerancing (GD&T) standards as they apply to engineering drawings. Standard practices used to convey part geometry in particular dimensioning, part layout, material conditions, and tolerances as they pertain to the stack up of parts to include operation, form, runout, profile, and location tolerances. The inspection methods used to check part compliance to geometric dimensioning and tolerances specified will be covered. (prereq: EG 124 , MA 126 , MA 127 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• know the fundamentals of GD&T symbols
• understand the use of GD&T symbols to convey fit form and function requirements
• demonstrate understanding on the use of GD&T in engineering drawings
• understand methods used to check for part compliance to GD&T symbols
