Week 3:- BiW Fixture Design Methodologies Challenges

UNDERBODY COATING To go with off-road (Driving over slush,big rocks,snow area and Loose gravel) our car body need extra protection to experience a lovely ride,Also driveway scarp is generate in underbody,So it’s better to get car under body treated if you will be offroading your vehicle. Pros(Benefits) -Minimizes…

BenchMarking It is a process where all the business model is compare to another business model by reversible methode and trying to develop a new structural model. To Develop/Design a complete car model it will take 3-4yrs.On that Bench-marking also a initial Phase in which we compare end user market experience and prepare…

Bill Of Material A group of semi finish goods(SFG) in inventory such as Raw materials,Assembly/Subassembly child parts,Standard components and its quanty as summerzied in a sheet called Bill Of Material(BOM).It shows or listed to complete a finish good product. BOM Helps- -Plan purchase of raw materials. -Estimate material…

Before handover to manufacturing need to do 2D finish after done 3D finish in Biw fixture design.All the dimensions of fixture unit and its child parts should mention clearly mentioned in drawing sheets.The detailing drawing standard should be change according to customer requirment.GD&T must used to reduce manufacturing…

Keysheet for the complete fixture assembly Below shown diagram is a projection view. Note-Also find attached pdf for your reference. Below shown diagram is a Isometric view.   Base unit and Fix pin unit Drawing for all child parts.

1.Drawing TemplatesEngineering is the graphical representation of structures,machines and their component parts that communicates the engineering intent of a technical design to the craftsman or worker who makes the product. -Drawing templates are basically the drawing standards as per customers specifications.-Drawing…

3D FINISH The 3D finish is the process where design is completely finishing and ready to finalsimulation and 2D details. In 3D finish we perform and ensure following below points. -Hole concentricity and hole sizes,All parts should check and conform hole sizes and there position each other for fitment. -Machining Area,The…

A.NO:-1 -It is the stages where 3D design being completely finish in 3D Software and ready for final simulation,show off and 2D purpose. -While finishing the design the nominality of is checked which ensure easy assembility of units. -The hole concentricity and hole sizes are checked to ensure the easy assembly of different…

BASE UNIT DESIGN A base unit is the unit design to mount all the units like clamp unit,pin unit,rest unit etc,also all other parts like the penumatic valve box,Trunking cable path are mounted on it.       FUNDAMENTALS OF BASE PLATE DESIGN A base plate should cover all the units with its outer periphery including…

A.NO-1 -A base unit is the unit design to mount all the other units(Clamp unit,Pin unit,Rest unit etc.)of the tool,also oter parts like pneumatic valve box,trunking cable path will also be mounted in a base unit. -As name suggested base,all the fixtures have must a base unit and the unit design is different according to…

3-2-1 Principle: The 3-2-1 methode is a work holding principle where 3pins are located in first principal plane i.e either XY,YZ,ZX and 2pins are located on the 2nd plane which are perpendicular to the first plane and atleast one pin on the plane which is mutually perpendicular to the 1st & 2nd planes.The ultimate goal…

Rest unit: This is a unit to designed for support car pannel using Myler/NC Block rest component is rested only, no upper clamp/force applied there,the purpose of design this unit only for rest car panel.Locating ,clamping and test unit also combined in one unit to reduce cost.There is no cylinder attached to it,rest myler,blade,risers…

 Pin unit is a unit design to locate car panel through pin.This unit consists up riser,Blade,Blocks,Shims/Spacer,Pin retainer and pin.Pin unit is design 3-2-1 locating principle,so that it restrict 6degree of freedom of the part. Fundamentals of pin unit design - It is necessary to have 2 pins to locate a car panel…

1.It is a technique normally involving with users as well as designers to be employed in creating a new technologies.                                   At the time of fixture design,the methodology divided into 4 subcatagories are…

1.For a project we assign tasks and responsibilities,so that we execute a systmatic plan to avoid crucial failure and risk.The stages of activities are define below. RFQ-Request for Queation is noting but the voice of customer where customer demand his requirments by documentation format,such as technical offer,commercial…

1.BIW abbreviates Body In White, which nothing but a core shell structured form of sheetmetal components in automobile manufacturing industries as before going to painting. OR BIW(Body In White) is a stage of Design or Manufacturing in automobile indusries,in which all the sheetmetal parts are assemble or join together(Welding,Riveting..)…
