PRODUCT DATA MANAGEMENT (PDM) v/s PRODUCT LIFECYCLE MANAGEMENT (PLM)


              In this modern world, we are surrounded by a lot of applications used in the system whether we go for organizations or home. Anyways, for the persons working in the domain of product development, might be aware with the applications of product lifecycle management. But most of the design engineers used to get confused b/w product data management (PDM) and product lifecycle management (PLM) applications. The aim for this post is to give a clear picture of PDM and PLM applications. As the name indicates, both of the terms deal with product design and management.

Product Data Management (PDM) system:-     

              A PDM system is a storage drive having an infinite disk space used for storing CAD models, drawings, BOM and other documents concerned with the product by checking out and checking in the files. The drawings and models are checked out and checked in while the documents are uploaded and downloaded in the PDM application. Intralink application is an example of PDM system.

              Product data management system serves as a product and process knowledge repository which promotes secured data exchange and integration among all the stakeholders including design engineers, project managers, sales managers etc. The functions involved in this system are updating, revising and release of models and drawings.

Product Lifecycle Management (PLM) system:- 

                 As the name indicates, this system deals with the management of entire lifecycle of a product. Product data management (PDM) system comes under product lifecycle management (PLM) system and enterprise resource planning (ERP) system. Teamcenter, Windchill are the common examples of PLM systems. There are basically two types of product development strategies. Among these, one is ‘starting from scratch’ which involves designing a new product which is not existing in the market as per the need or demand of the product from the side of customer and other is ‘modifying an existing product’ which involves updating and modification of product as per the customer needs.

                  A product undergoes different stages in its lifecycle independent of the type of product development. The different stages are: - design, prototype, production, inventory and obsolete (end of the product). The activities such as ECR/ECO process, updating BOM, managing change notifications and problem reports, communication with the vendors or suppliers etc. can be performed with the help of PLM system.

                 For efficient and proper working of PLM systems, it requires more and more amount of involvement and integration among various departments of organization.

WELD SYMBOLS USED IN DESIGN

WELDING SYMBOLS AND ITS MEANING USED IN DESIGN                                 It’s a very usual aspect to use weld symbols in most of the mechanical drawings. Nowadays, it has become very important to have knowledge concerned with the welding symbols. There is a basic format given for showing the weld types used with its specifications. The welding standards have been varying in different areas. These standards had been updated from time to time by various non-profit organizations like AISC (American Institute of Steel Construction), API (American Petroleum Institute), AWS (American Welding Society) in USA and many other countries. In India, the welding standards are summarized by BIS (Bureau of Indian Standards) in which they are having certain IS (Indian standards) numbers or codes which are followed by most of the Indian companies.                        The above fig. shows the format used for annotation of weld symbol

OCTAHEDRAL SHEARING STRESS THEORY

OCTAHEDRAL SHEARING STRESS THEORY                       According to this theory, the critical quantity is the shearing stress on the octahedral plane. The plane which is equally inclined to all the three principle axes is called the octahedral plane. τ oct = (1/3) [(σ 1 – σ 2 ) 2 + (σ 2 – σ 3 ) 2 + (σ 3 – σ 1 ) 2 ] 1/2                                                                                        where, τ oct = octahedral shearing stress Failure is said to occur when τ oct = ((√2)/3) σ e            This theory holds feasible for ductile materials and is similar to Von Mises theory.

GUEST’s or TRESCA’s THEORY

MAXIMUM SHEAR STRESS THEORY (GUEST’s or TRESCA’s THEORY)                  According to this theory, the elastic failure occurs when the greatest shear stress reaches a value equal to the shear stress at elastic limit in a simple tension test. This theory is considered for ductile materials, since shearing doesn’t occur in brittle materials. (½)(σ 1 – σ 3 ) = (½)σ e           or                                                               σ 1 – σ 3     =       σ e                   The maximum shear stress theory is also known as Guest’s or Tresca’s theory.
