Geometrical Tolerancing to BS 8888 & ISO Standards – Level 2

The course covers more advanced aspects of geometrical tolerancing and its application and interpretation. Completion of the Level 1 course is a prerequisite for anyone wishing to attend the Level 2 course. The course is based on BS 8888 and ISO standards (a version is also available based on the American ASME Y14.5 standard). Delegates are provided with comprehensive course notes, and a workbook with questions and exercises to accompany the training material.

Description

Course Aim:

The course covers more advanced aspects of geometrical tolerancing and its application and interpretation. Completion of the Level 1 course is a prerequisite for anyone wishing to attend the Level 2 course. The course is based on BS 8888 and ISO standards (a version is also available based on the American ASME Y14.5 standard). Delegates are provided with comprehensive course notes, and a workbook with questions and exercises to accompany the training material.

Course Content(Modules):

· Review of Level 1 material 

· Geometrical specifications (additional indications and modifiers) 

· Grouping features together (CZ, SZand SIM) 

· Advanced datum systems 

· Maximum Material Requirement applied to datum features

· Least Material Requirement 

· Multiple tolerances applied to groups of features

Learner Outcomes:

Participants will learn about:


· Tolerance zone definitions (fixed, variable, limited, etc) 


· Tolerance feature definitions (filters, associations, etc) 


· Plane and feature indicators (intersection plane indicators, etc) 


· Adjacent indications (UF, ‘between’, ‘all around’ etc) 


· Grouping features (nX, ‘all over’, etc) 


· Grouping tolerance zones (CZ, SZ, CZR, and SIM) 


· Multiple tolerances applied to groups of features (e.g. hole patterns) 


· Datums and ‘situation features’ 


· Common datums based on aligned and non-aligned features 


· Datums based on groups of features 


· Datums based on complex surfaces 


· How location and orientation tolerances control form 


· Maximum Material Requirement and Virtual Condition 


· Datums based on Virtual Condition Boundaries 


· Least Material Requirement 


· Tolerances applied to non-rigid parts (ISO 10579 and Freestate condition)
