Learn all about solid model tolerancing

An Effective Training product story

Effective Training now offers a one-day solid model tolerancing course for designers, engineers and managers who are implementing maths-based product development processes.

Effective Training now offers a one-day solid model tolerancing course for designers, engineers and managers who are implementing maths-based product development processes.

The course explains fundamental definitions, concepts and methods from the new ASME Y14.41-2003 standard on "Digital product definition data sets".

The course, "Solid model tolerancing", was developed by ETI president, Alex Krulikowski, Chairman of the ASME Y14.41 Committee on Solid Model Tolerancing.

It is intended for designers, engineers, and managers who are implementing maths-based product development processes.

The Y14.41 standard establishes requirements for preparing, organising and interpreting 3D digital product images.

It also provides a guide for CAD software developers working on improved modelling and annotation practices for the engineering community.

The "Solid model tolerancing" course is not based on any single CAD system or product development process.

It covers concepts and standards that can be applied with a number of CAD systems.

"ASME Y14.41 advances the capabilities of Y14.5, 'Dimensioning and tolerancing', the widely used standard pertaining to 2D engineering drawings", said Krulikowski.

"It defines the exceptions and sets forth the requirements to existing ASME standards for using product definition data or drawings in 3D digital format".

"The 'Solid model tolerancing' course explains the benefits of a math-based product development process, discusses details of the new standard, and teaches how to create model and drawing (reduced dimension drawings) as a data set in accordance with Y14.41".

The one-day course discusses the gaps, issues and challenges facing industry in transitioning to a maths-based product development process.

It also explains the current status, issues and future of tolerancing models in industry.

Krulikowski has also established a digital tolerancing forum to discuss issues related to tolerancing of solid models.

The forum shares information on the capabilities, technical and implementation issues, and uses of digital tolerance information.
