Engineering Vocabulary

Here are some concepts and acronyms explanation that helps everyone intersted in engineering and technology.

Virtual Manufacturing

Virtual manufacturing

A virtual manufacturing means the implementation of digital technologies that allow modeling, simulation, collaboration, verification, interaction and validation of the design product and the manufacturing process.

Ubiquitous Manufacturing

Augmented reality

To have the capability of real time traceability, visibility and interoperability in improving the performance of work stations planning, execution, and control using radio frequency identification (RFID) technology, sensor networks and augmented reality


This is the acronym of Design For Manufacture and Assembly, this a methodology adopted to improve the design  of a product for determined objective.

This method permits the following benefits:

  • Lower development cost
  • Shorter development time
  • Higher quality
  • Incorporate domain specific constraints early in the design phase

Here’s an example of DFMA design improvement:

DFMA design improvement


DMU is an acronym of Digital Mock-up which is a digital alternative  to constructing physical prototypes.


STEP compliant numerical control is a standard for exchanging data between CAD, CAM and CNC machine tools.STEP NC answers the question “What to do?” throufgh three essential concepts : Working step, Feature and operation.

You will find task description , machining feature catalog and so on.


PDM is an acronym of Project data management ,this means management of product data by the means of softwares

Reverse Engineering

according to CRC press 2010  reverse engineering is “Reverse engineering (RE) is a process of measuring, analyzing,  and testing to reconstruct the mirror image of an object or retrieve a past testing  It is a technology of reinvention, road map leading to reconstruction and reproduction. it’s also the art of applied science for preservation of the design intent of the original part.

“RE is the process of duplicating an item functionally and dimensionally by pgysical examining and measuring existing parts to develop the technical data resuired for competitive procurement ” MIL HDBK, 2006
