FMEAFailure Mode and Effects Analysis

FMEA is an analytical methodology used to ensure that potentialproblems have been considered and addressed throughout theproduct and process development cycle. Involves reviewing asmany components, assemblies, and subsystems as possible toidentify failure modes, and their causes and effects. For eachcomponent, the failure modes and their resulting effects on therest of the system are recorded in a specific FMEA worksheet.There are numerous variations of such worksheets.

A few different types of FMEA analyses:• Functional• Design• Process

Design Methodology | 2016

• Discover the potential failures, their potential causemechanisms and the risks designed into a product orprocess

• Develop actions that reduce the risk of failure• Follow-up and evaluate the results of actions on the risks

that were discovered

FMEA - functions

Design Methodology | 2016

SFMEA - System Failure Mode Effects Analysis, analyzing systems and subsystems in the early (conceptual) stage and focuses on the interaction between systems and system elements.

DFMEA - Design Failure Mode Effects Analysis , analyzes the product before production starts. It focuses on the types of defects caused by deficiency in the design of the (draft).

PFMEA - Process Failure Mode Effects Analysis, analyzing manufacturing and assembly processes, the process deficiencies manufacture or assembly.

Product Lifecycle Management

Design Methodology | 2016

Product lifecycle management (PLM) is the processof managing the entire lifecycle of a product frominception, through engineering design andmanufacture, to service and disposal ofmanufactured products. PLM integrates people,data, processes and business systems and provides aproduct information backbone for companies andtheir extended enterprise.

PML

Within PLM there are five primary areas:

• System engineering SE• Product and portfolio PPM• Product design Cax• Manufacturing proces management MPM• Product data management PDM

PML

Hyper KVSStructural data management system in the Volkswagen group. Thesystem serves as a central documents archive for the global interchangeof all corporate documents regarding construction data within processchains as well as respective description documents. The system stores allCAx data such as 3D models, 2D drawings and manually generateddocuments.http://plm.t-systems.cz/en/cad-cam/other-products/hyperkvs.html

Key functions of the Hyper KVS system include:• Search and information • Data archiving, working with versions• Data interchange with external partners• Data translation into various formats

ECR - engineering change request

An engineering change request form is used to describe a suggestedenhancement or problem with a product. The form initiates thechange process — it promotes discussions within the organizationto help determine the impact of a change and the best possiblesolution. The ECR form is circulated and reviewed among keystakeholders. It is the predecessor for an engineering change order(ECO - engineering change order), which describes the details of achange and may specify how a change should be implemented.

TEAMWORK

Designers cannot work independently of theirenvironment - they depend on the results produced byothers and others depend on their results. They aremembers of their departments, which in turn are parts ofthe company. Only the coordinated activities of allparticipants will lead to a satisfactory overall result.

TEAMWORK

Computer-aided design (CAD) is the use of computersystems to assist in the creation, modification, analysis,or optimization of a design. CAD software is used toincrease the productivity of the designer, improve thequality of design, improve communications throughdocumentation, and to create a database formanufacturing. CAD output is often in the form ofelectronic files for print, machining, or othermanufacturing operations.

TEAMWORK

Computer-aided engineering (CAE) is the use of computersoftware to simulate performance in order to improveproduct designs or assist in the resolution of engineeringproblems for a wide range of industries. This includessimulation, validation, and optimization of products,processes, and manufacturing tools.

TEAMWORK

Manufacturing engineering (ME) is a discipline ofengineering dealing with different manufacturingpractices and includes the research, design anddevelopment of systems, processes, machines, toolsand equipment. The manufacturing engineer's primaryfocus is to turn raw materials into a new or updatedproduct in the most economic, efficient and effectiveway possible.

Design Methodology | 2016

TEAMWORK

Project Engineering (PE) bridges the boundaries betweenengineering and project management, leading thetechnical workers who contribute to the building ofstructures or products. In some cases, the project engineeris the same as a project manager but in most cases thesetwo professionals have joint responsibility for leading aproject.
