Level 1 Online Course Details
The Level 1 program is the first part of a professional level course that provides a solid introduction to geometric tolerancing. It is delivered per the ASME Y14.5-2009 standard and consists of 8 interactive units. This program has been presented and refined over the past 30 years and covers what personnel need to know in order to work in an engineering, manufacturing and quality environment on a daily basis. The program is designed to build knowledge in steps, keeping the students engaged all the way through. This program is great for people new to the subject or those looking for a refresher course.
The units start with a series of video clips of both Al Neumann and Scott Neumann teaching the lesson. Al and Scott trade off, sportscaster style, teaching the subject by talking about the engineering drawings, showing computer animations and using wood and plastic models to demonstrate inspection techniques. In between the video clips, the students are asked interactive questions on screen. The questions range from multiple choice, drag and drop, or hot spot buttons. After the questions, Al and Scott then provide the answers before continuing to the next topic. The student’s grades are tracked and reported at the end of each unit.
The students may follow along with the lessons in their GeoTol Pro workbook with pages that match the slides on screen. The 12 month access also allows the students to go back and review both the video clips and questions to reinforce the concepts as needed. See the program outline for the topics covered.
The program starts with Unit 1 showing a basic introduction to the symbols, terms and theory of GD&T along with practical demonstrations on basic measurement procedures. In Unit 2, the students will learn the important concept of the Limits of Size (Rule #1) and the problems with the old plus/minus tolerancing to locate features. With models and exercises in Unit 3, the students will learn basic datum reference frames and the concepts of profile, position and how to correctly apply and interpret the MMC, LMC and RFS feature modifiers. Inspection procedures and inspection reporting shown in Unit 4 reinforce the concepts of position and feature modifiers. Virtual size calculations are shown in Unit 5 to lay the ground work for functional gauging, MMB modifiers and calculating position values in the Level 2 training. Unit 6 continues into more complicated datum reference frames and illustrates how datums constrain a part’s degrees of freedom. After this Level 1 training, the student will have a solid grasp on the three major concepts in geometric tolerancing, datum reference frames, position, and profile. With the included units 10 and 11, this program also covers the form and orientation tolerances in depth. See Level 2 for the more advanced topics covered.
