CAD/CAMCAD/CAM is a term which means computer aided design and computer aided manufacturing.

It is a technology concerned with the use of computer to perform certain functions in design and production

Form of Data received by JCPLWireframe data

IGES form

Manual Drawings

Manual Drawing Send by Honda to JCPL

CAD CAM DevelopmentThe Manual Drawing and IGES file is given by Customer to the JCPL.Verification of data made by making comparison between IGES data and manual drawing.Make some decision about part process , die and types of die Required for operation.

Designing

Designing of DieCreate the Model of die required using 3-D software's.

Design 1st part of die(punch) and then 2nd part of die (cavity).

Any modification or alteration require is made after that designing is complete

Manufacturing of DieIn Manufacturing following Parameters are Selected before manufacturing Material Selection Process Selection CNC Machine Selection Tool selection Tolerance

Generation of NC FilesNumerical control is a form of programmable automation in which the process is controlled by numbers ,letters, and symbol.

Every operation has its different NC program.

Creating a new NC program is easy than altering a already present NC program.

NC FileIt is detailed step by step set of directions which tells the machines tools what to do.NC file is combination of . G-code M-Codes etc. C.L Data

G Codes and M codesG commands often tell the control what kind of motion is wanted.G00 Rapid positioningG01 Linear interpolationG94 Feed rate per minuteM-codes call for machine functions.it performs different function of machine.M02 End of programM05 Spindle stopM08 Coolant on.

Transfer of NC Data To Controller unit of CNC MachineTransfer of Data made in given two waysMDI Manual data input (MDI)Direct numeric control (DNC) Direct Numeric Control Method is further divided in two more ways. Flash Disk Direct Connection to Computer using cabling

What is dieA die is a special tool used in manufacturing industries to cut or shape material using a pressit consist of punch and cavity.

Types of DieBlanking dies.Piercing diesForming dies.Bending dies.

Blank and Piercing dieBlank Die

Blanking is a shearing process where a punch and die are used to create a "blank" from sheet metal or a plate.If this piece is not scrap its part blank then called its cutting tool blanking die Piercing Die

Piercing dies are same as blanking dies but it used for piercing in parts hole and slots. if a dropped piece after cutting in a sheet is scraped then its die called piercing die

Forming and Bending Die Forming DieSome time parts surface have many slots, groves and others shapes. Then die used for making these slots and groves called forming dies Bending DieThe bending operation is the act of bending blanks at a predetermined angle.

APPLICATION of CAD/CAM

Die and mold designing.Die and punch for sheet metal forming. Aerospace parts.Automobile parts.Warfare equipments.Surgical instrument.Precise parts.

Advantages of CAD CAMHigh degree of accuracy.Complex machining operations.Increased production rate.Reduce space requirements.Reduction of human error.Reduction of scrap.Skilled worker is not required.Greater operator efficiency.Operator safety.
