Functions Of CAD CAM 2D And 3D Computer Science Essay

The basic thought of this assignment is to propose package to a Client who is a little tooling maker. The concern of the Client is originally to plan, analyze and industry parts and tools for modeling intent of plastic containers, for illustration bottles, storage boxes, etc. The client uses AUTOCAD and MASTERCAM in order to plan and fabricate the parts and tools but most of the clients of the client usage SOLIDWORKS, AUTOCAD, INTERGRAPH NX and 3D STUDIO MAX. So the client has to construe or translator before the usage of the design of the client. The chief aims of the client are fixing CAD theoretical accounts for the tools and parts, making both technology and production drawings, analysis of mechanical and injection casting and besides developing CNC portion plans for the tools and parts to be manufactured. But due to difference of package used by the client and the clients there exists an importance of communicating with the client before the designs are finalized to be manufactured. The clients have some demands like the client should be working under the ISO9000/I and the files and informations that are received and created should be controlled and managed.

CAD stands forA computer-aided design. It is besides known as CADD, which stands forA Computer-Aided Design & A ; Drafting. This package is used in making programs and to build drawings by designers, applied scientists, drafters and creative persons. The package is really efficient as the package has the capableness to enter lines on vectors based on mathematical equations. It besides has characteristics such as the drawings can be twisted and moved and the image is automatically adjusted.

CAM stands for Computer Aided Manufacturing. The system sets the tool way and executes accurate machine operations based on the design of the portion or tool to be manufactured. CAD and CAM are connected toA each other straight. The integrated CAD/CAMA system is so takes the design generated by the computing machine and is so fed into the fabrication system and so the design is changed into multiple computer-controlled procedures, such as boring or turning.

OVERVIEW OF SOLID WORKS:

First of all Solid plants will work by making portion in 3D or solid signifier. They are three constituents which are mainly utilizations in solid plants that is Part, Assembly and Drawing. Part define by it study and selected characteristic. Assembly is how all parts must be assemble in one unit, parts assemble by user adding mate between parts. Drawing is for detailing and adding dimensions to portion. solid works chief thought is user must make pulling straight in 3d or solid signifier.from this solid signifier user can piece it straight on there work station by look intoing clangs and functionality of it. Making pulling in an easy manner and drop the solid to pulling block

Procedure:

Part:

Part is created by study

Sketch is the base to specify the portion, signifier and characteristics

Before start making studies we must choose plane or face where the study will be sketch on it and add characteristics.

Added characteristics

Assembly:

This is nil but how all parts work together in assembly. There after we have to look into it out for clangs and its functionality. first of all parts are inserted in assembly by insert constituent tool.After infixing all parts in a workspace and at that place after we have to look into it out for functionality.Mate is a bid how parts mate with each other.After piecing all parts its represents like that

Drawing:

This is usage for detailing portion by adding dimension to it. The pictural represents for drawing is

DIFFERENCE BETWEEN SOLID WORKS AND AUTOCAD:

Solid works is a “ parametric ” solid modeler used for 3D design.

AutoCAD is chiefly a 2D design tool that does hold some 3D capableness,

It is easy to compare any parametric solid modeler even though 3D is improved in AutoCAD 2007.

Autodesk ( Godhead of AUTO CAD ) makes a merchandise that is about indistinguishable to solid plants called Inventor, which is a parametric plan for design of solid parts and assemblies.
