## INR 0.8 Million per Kg is the Cost of NOT Doing Design Optimization – How?

Trade-off, to my opinion, is the major reason of optimization driven design. Trade-off among performance, time to market, regulatory requirements and all this at a right COST.

However, while calculating cost, a broader view taking all the processes for … Read the rest

## Design for Additive Manufacturing Worksheet

With the popularity and development of additive manufacturing process, the process of creating good Design for Additive Manufacturing (DfAM) is getting complicated.

Making decision on whether a design is really good to go for AM or not is getting difficult … Read the rest

## Do Value Engineering Upfront, Right at Design Stage

Typically the value engineering (VA/VE) practices take already designed, validated and productionised components and apply the VA/VE methodologies to increase the value of the product either by reducing cost (weight) or increasing functionality.

## Why I-Section Beam is structurally better than same weight other sections?

When deciding for the beam section to have, the first consideration to be done is what purpose it need to serve i.e. what kind of loads it will deal with. In general the following cross section choices are available for … Read the rest

## How to calculate vehicle speed from engine RPM and vice versa

Suppose your motor vehicles speedometer not working and you need to know your vehicle speed for the given engine speed for a certain gear ratio. How you can do that , let’s see..

Say, Engine rpm= 3000
Gear ratio=1.5

## Bolted Joint Design Calculation Example for Joint in Tension

Properly designed bolted joint is extremely important for striking the balance between the cost and life of the joint.

As a design engineer, for a good bolted joint design, for a given loading conditions and materials of the abutments, you Read the rest

## Worst Case Method Assembly Tolerance Stack up Calculation for Non-Symmetric Dimensional Tolerances with Example

If you are wondering what is stack-up analysis/calculation, the answer is determining worst case scenario. Moreover, the problem can sorted out in early stages of design rather than undergoing prototyping and finding out the issue.

## DFMEA Creation Tutorial with Example

What is DFMEA?

DFMEA is Design Failure Mode & Effect Analysis. It is the application of FMEA to a specific product/system in a disciplined manner that anticipates failures to prevent their occurrence in design.Read the rest
