Search Beginning SmartGD&™ for Design, Manufacturing & Inspection
(Available for ASME Y14.5 and ISO 1101)
Objectives:
Upon completion of the course, students will be able to:
Recognize and name the common GD&T symbols, including Geometry Control Tool symbols, Datum Feature labels, Feature Control Frames and Material Condition Modifiers
Comprehend the differences between, and work effectively with nominal, BASIC and reference dimensions
Understand and work effectively with Cartesian coordinate systems and 3rd angle projection drawings
Recognize the four distinct categories of geometric characteristics: size, form, orientation and location
Apply the most important Geometry Control Tools (Position, Flatness, etc.) to tolerance simple objects
Comprehend the "Material Condition" concept, the Envelope Rule and the Maximum Material Condition tolerance bonus
Understand Datum Features and how they define Cartesian coordinate systems
Create and "read" Feature Control Frames
Understand the objectives and benefits of GD&T versus classical methods for managing machine part geometry
Duration:
2-days
This course is delivered in two days, providing adequate time for hands-on implementation of concepts in early encoding and decoding exercises.
Target Audience:
All persons dealing with Product Design, Drafting, Tool Design and Maintenance, Machining, Manufacturing Management, Manufacturing Process Control, Inspection, Robotic and manual Assembly, Vendor Relations and Purchasing.
Materials:
Course handouts include a dedicated course manual and sundry articles and flyers. Participants are encouraged to provide their own lined pads and pencils (making it easy to erase occasional mistakes), and examples of drawings (with overhead slides) and parts they wish to discuss.
Confidentiality:
In the case of in-house corporate classes, a non-disclosure agreement should be implemented between the sponsor and Multi Metrics, Inc. prior to inception. Drawings and parts brought to public classes should be non-proprietary in nature.
