NewswireToday - /newswire/ - Appleton, WI, United States, 03/23/2009 - New texts and course materials written to explain the new Y14.5-2009.

The ASME Y14.5-2009 standard on Dimensioning and Tolerancing has finally hit the streets. It represents a radical change from the ASME Y14.5M-1994 standard. A wide variety of new rules and symbols are included. For companies that want to adopt the new standard there will be a learning curve. The Y14.5-2009 standard will allow designers to express their design requirements more clearly. Product representations will be more specific in conveying tolerancing needs. Products will be more easily manufactured, and appropriate inspection techniques clarified with these new tools.

As with all standards, the ASME Y14.5-2009 standard is written in such a concise way as to be difficult to learn from. To support this learning process, I’ve written 3 new books and made a film series to explain the new standard.

One of the textbooks is being sold by ASME as a dimensioning and tolerancing handbook. It is entitled: Geometric Dimensioning and Tolerancing - Applications, Analysis & Measurement [per ASME Y14.5-2009]. It is almost 600 pages in length and covers virtually every facet of dimensioning and tolerancing including the new principles, rules and symbology.

The second book is called WORKBOOK AND ANSWERBOOK for Geometric Dimensioning and Tolerancing [per ASME Y14.5-2009]. This 367 page book has 5 sections. Section 1 will provide information (rules, principles, symbols and changes) necessary for anyone wishing to progress to the rest of the book. Section 2 provides worksheets for a wide variety of GD&T topics. It includes applications problems from a wide variety of industries, tolerance analysis problems and general GD&T knowledge questions. Section 3 consists of word problems that include questions about every geometric characteristic symbol, datum features, boundaries and rules. Section 4 consists of questions and illustrations that specifically apply to the new rules in Y14.5-2009. Section 5 is the answerbook. It shows, in great detail, how each problem in the workbook is solved.

The third book is entitled ‘NEW RULES’ in GD&T [per ASME Y14.5-2009] is based on the ASME Y14.5-2009 dimensioning and tolerancing standard. This 160 page text and workbook/answerbook reflects new symbology, rules and basic principle revisions that took the Y14.5 committee almost 15 years to complete. It was written to specifically highlight the revised concepts covered in ASME Y14.5-2009 as well as to explain some of the more difficult and advanced concepts allowed by older versions of Y14.5, but extended in the 2009 revision.

The “NEW RULES” in GD&T book has available for purchase an accompanying DVD series wherein the concepts that are new to the ASME Y14.5-2009 standard are explained in great detail. This DVD series will make clear the sometimes difficult to understand changes instituted in the revised Y14.5-2009 standard. This film works in conjunction with the “NEW RULES” in GD&T book and refers to pages from the book during the presentation.
