GeoTol Applications with Stacks Program

Applications with Stacks Workbook

This workbook is designed to educate students on reasonable and proper application of geometric tolerancing to parts and assemblies. It follows along with the Geometric Tolerancing Applications with Stacks Program. The workbook starts out with a quick review of the major concepts of geometric tolerancing and the necessary fastener formulas used to calculate position tolerances. The review also includes examples and illustrations on when to use the feature and datum modifiers MMC, RFS and LMC.

The workbook continues with a series of case study problems the student must solve. The problems consist of practical examples of parts and assemblies that can be found in an industrial environment. The introduction in each case study provides design information and functional requirements about the problem. In the hands-on lessons, students must apply necessary geometric tolerancing to the parts to ensure assembly and functional requirements. This includes the establishment of DRF’s, the relation between the datum features, and the location of all the remaining features to the DRF. The students must also apply any necessary form, orientation, profile, position and runout tolerances. This workbook contains a variety of problems including machinings, sheet metal, plastic applications with a variety of functional design requirements.

The students must also use the fixed and floating fastener formulas to calculate proper mating conditions. The drawings should be complete, including the application of realistic tolerance values in the feature control frames for the given situation and manufacturing concerns. The student should also pay particular attention to the proper selection of MMC, RFS and LMC feature and datum modifiers. The workbook uses geometric tolerancing completely. Plus/minus tolerancing is used only for the size of features and not the location of features.

The Applications with Stacks Workbook has two parts, the application of geometric tolerancing to parts and assemblies and the tolerance stacks evaluation process of those applications. If the student is interested in just the application of geometric tolerancing, the stack problems need not be completed. However, if the student desires to perform any of the stack problems in this program, the knowledge of tolerance stacks is a perquisite. For detailed information on tolerance stacks see the Geometric Tolerancing Stacks and Analysis Workbook by Al Neumann. The Applications with Stacks Workbook contains the case study problems as well as the solutions. It is a excellent reference for applying geometric tolerancing to parts and assemblies.

Special feature for instructors/leaders: The pictures in the workbook correspond to and match the Instructor PowerPoint Kit and DVD/Video Series. Also available is an optional plastic model set. The instructor/leader can use these materials to provide the students with an exciting/practical hands-on learning experience. The workbook is loaded with student workshop exercises. The Geometric Tolerancing Applications with Stacks Workbook is perfect for schools and corporate in-plant programs. It can be used alone as a self study or reference or in conjunction with the other training materials.

A popular presentation is to use the Geometric Tolerancing Stacks and Analysis Workbook and the Geometric Tolerancing Applications with Stacks Workbook simultaneously. The student would alternately complete a lesson in the Stacks book and afterwards solve a practical case study problem in the Applications book. This format provides variety in the lessons and practical applications at the same time.
