Solving Quality Issues by Design - A G D & T and Tolerance Stack Analysis Approach

White Paper on Importance of G D and T with Tolerance Stack Up Analysis for developing 0 PPM Designs and Solving Quality issues is presented with case study involving an Electric Motor Designed and analyzed using SolidWorks and SigmundWorks Software. Quality in Assembly Build and Performance affects profitability. Acceptable quality depends on drawings that define design specifications. G D & T Drawings developed according to ASME Y14.5/ ISO Standards and ensured for correctness and completeness is the first step. Assigning least cost tolerances, predicting assembly build and performance is the next step towards developing a fool-proof quality regime. This is done by performing Tolerance Stack Up Analysis. Implementing technological tools to achieve this has following inherent benefits: 1. Correctness and Completeness of Drawings eliminates ambiguities, re-work and errors in production/ inspection processes 2. Identification of dimensional parameters affecting assembly build...

Design Validation of Automotive Systems - Benefits of using SolidWorks Simulation

Image
A new White Paper has been published by EGS India on the Benefits of Design Validation for Automotive Systems. Automotive Industry is constantly looking at ways and means of reducing costs and staying profitable while delivering on time. Common denominator in all these challenges is Design. Companies investing in developing indigenuous Design Technologies, emerge successful in the world market and are able to sustain and innovate at a higher pace than the rest of the competition. This is possible on account of the following capabilities: Delivering products faster with Up-front Engineering Design Validation as a part of the Product Development Process while compressing the cycle time Lean Design by incorporating Value Engineering as a part of the Design Process ensuring evaluation of least cost alternatives before even the first prototype is developed Increasing Reliability by Design – an Initiative that will eliminate hidden costs associated with product recall, re-design and/ or r...

EGS India to participate in Access 2010 hosted by TANSTIA - ACCESS’10 is the second in the series of International Machine Tool and Engineering Expo

EGS India is participating in Access 2010 and can be visited on Booth 108. Focussing on emerging Technologies and Benefits for the Machine Tool Industry, EGS India will be highlighting the benefits of SolidWorks 2010, SigmundWorks Tolerance Analysis Software and SolidWorks Simulation as a Design Validation Tool for Product Design and Development. Additionally the ability to save, re-use and update Engineering Data using Enterprise PDM (Product Data Management) as well Publishing Manuals and Documentation using 3DVia Composer are the highlights of the program. The Expo is being conducted at Chennai Trade Centre between February 7 -to- February 9, 2010. All are welcome and invited to Booth 108.

Sustainable Designs helps develop Profitable Products - A SolidWorks Initiative

Image
Sustainability Xpress could not have been released, by SolidWorks Corporation, at a better time, with the world looking at Initiatives to address Global Warming, Reducing Greenhouse Gases and Carbon Footprint. A simple add-in inside SolidWorks, it helps Designers understand the impact of their designs on environment early in the design stage. In terms of recent economic downturn how do sustainable designs result in higher profit, larger market share and improved sales for engineered products? Sustainable designs need to have Conservation as the central theme. Conservation of: Material Energy Resources Conservation of Material helps lower cost of raw material used, select material that can be recycled and evaluate alternate materials that are eco-friendly. These objectives align perfectly with the cost reduction objectives of any organization that intends to remain competitive. Conservation of Energy focuses on Energy used to produce a product as well as energy consumed by the pro...

Simulation - Cure all for beleagured engineering enterprises?

Image
In these days of economic challenges, companies are forced to look at ways and means of reducing costs to survive and stay profitable. Some of the immediate priorities that need urgent management focus include: 1. How to reduce product cost to sustain healthy margins? 2. How to innovate and deliver products of high value without compromising on safety? 3. How to increase an already shrinking market share? 4. How to eliminate warranty costs, product recall and re-work? The questions are unending. This is just a partial list. The answers just do not seem to be there. A careful analysis of all the questions, posed above, provides a common denominator - Design Product cost is dictated by the Bill of Materials and Drawings. Innovation and USP of a product is driven by product function and efficiencies. Increasing market share is directly related to selling better products of higher value at affordable (read not lower) cost. Warranty issues, recall and re-work relate to product not...

GD & T - Power of Feature Control Frames using SolidWorks

Image
Feature Control Frame forms the heart of the Geometric Dimensioning and Tolerancing ( GD & T ) practice for engineers involved in creating, manufacturing and inspecting designs. In fact it is the greatest invention of engineering expressions in symbolic language that it is finding unilateral acceptance by the engineering community as a whole. For the un-initiated, let us considere a hole dimensioned as follows: Read from left to right, the Feature Control Frame states that "Position of the Axis of a pattern of 8 holes when produced within stated size limits, can be off-centre within a diametral tolerance zone of 0.50 when produced at Maximum Material Condition, when the part is located on Datum A as Primary, Datum Feature of Size B when produced at Maximum Material Condition as Secondary and Datum C as Tertiary references." Feature Control Frames have a characteristic symbol in the first cell, a tolerance value with a zone descriptor and material modifier (if any) as the...
