Chapter
Dimensioning with Geometrical Tolerances
The advantages of the geometric specification of a product are here illustrated by converting a traditional 2D coordinate tolerancing drawing using the geometrical tolerance method. The new language of symbols...

Chapter
Run-Out Tolerances
A run-out error is the surface variation that occurs relative to a rotation axis. There are two types of run-out controls: circular run-out (2D) and total run-out tolerances are composite controls that defin...

Chapter
Geometrical Specification for Non-rigid Parts
In the absence of other indications, all the specified dimensions and tolerances are applied and controlled without the action of any force, except gravity, but components such as thin metal and flexible parts...

Chapter
Orientation Tolerances
Orientation tolerances (parallelism, perpendicularity and angularity) are used to control the orientation of a feature (surface or feature of size) with respect to one or more datums. When the orientation tole...

Chapter
Introducing GD&T and GPS
The technical product documentation that is currently drawn up in many companies is unfortunately still ambiguous and contains many errors, such as erroneous datums, imprecise or missing distances, as well as ...

Chapter
Interdependence Between Dimensions and Geometry
In ISO GPS terminology, the maximum material requirement, (MMR) and least material requirement (LMR) represent two of the fundamental rules on which geometrical dimensioning with tolerances is based, and which...

Chapter
Linear Sizes
In the past, the verification of the local size of workpieces was carried out using traditional metrological instruments, such as callipers and micrometres, or using hard gauges to check for conformance with t...

Chapter
Form Tolerances
It is possible to control four form tolerance types: straightness, flatness, roundness and cylindricity. The chapter covers all the concepts necessary to define specification operators (according to ISO 17450-...

Chapter
Location Tolerances
This chapter describes how to use location tolerances to specify an allowable location error. The location tolerances that should be used, in function of the feature of the workpiece that has to be located, ar...

The Geometrical Product Specification (GPS) Language
The main concepts proposed in this chapter have the aim of expressing the fundamental rules on which the geometrical specification of workpieces can be based through a global approach that includes all the geo...

Chapter
Profile Tolerances
A geometrical tolerance on a profile is one of the most versatile and powerful instruments that can be used for functional dimensioning, and is the tolerance most frequently used by designers. A profile may in...

Chapter
The GPS and GD&T Language
This chapter is focused on the main differences between the ISO and ASME standards in the geometrical specification domain of the industrial products, and it starts with details on the historical evolution of ...

Chapter
Datums and Datum Systems
A datum system has the purpose of defining a set of two or more ideal features established in a specific order (for example, a system made up of a triad of mutually orthogonal planes) that allows not only the ...

Mixed Reality-Based Support for Total Hip Arthroplasty Assessment
The evaluation of hip implantation success remains one of the most relevant problems in orthopaedics. There are several factors that can cause its failure, e.g.: aseptic loosening and dislocations of the prost...

Interpreting Emotions with EEG: An Experimental Study with Chromatic Variation in VR
Develo** great products is not simple; users want products that can constantly adjust to their needs. The product development process should consider not only the users’ requirements and wishes but also thei...
