CAD (Computer Aided Drawing) is used for engineering design and involves defining geometric models and interfaces for design and analysis. CAM (Computer Aided Manufacturing) is used to transform engineering designs into products and involves geometric models, process planning, and NC programs. The document compares CAD and CAM, outlining their processes, software used, advantages like minimized drafting, easier modifications, and disadvantages such as training costs and potential issues from power cuts. It provides contact information for LUPITER TECHNOLOGIES, describing CAD and CAM services.
Difference between cad &cam
- 2. WHATISCAD? CAD (Computer Aided Drawing/Drafting) Basic : CAD is the implementation of digital computers in engineering design and production. Involved processes: Definition of a geometric model, definition translator, geometric model, interface algorithm, design and analysis algorithms, drafting and detailing, documentation. Requires : Design conceptualization and analysis. Softwares : AutoCAD, Autodesk Inventor, CATIA, SolidWorks
- 3. WHATISCAM? CAM (Computer Aided Manufacturing) Basic : CAM is the implementation of computers in transforming engineering designs into end products. Involved processes: Geometric model, process planning, interface algorithm, NC programs, inspection, assembly and packaging. Requires : Control and coordination of the necessary physical processes, equipment, materials, and labour Softwares : Siemens NX, Power MILL, WorkNC, SolidCAM
- 4. ADVANTEAGESOFCAD Minimizes the requirement for huge numbers of an expensive draftsman in designing of a product. It can be used directly in order to generate cutting data for CNC machines. Scaling, re-scaling modification in drawings and models is easier and automatic and accurate. Storage and retrieval of models is easier. Design data can be shared in computerised manufacturing management systems. Precise 3D models can be examined before making expensive materials. It increases the speed of production and requires less labour. Multiple copies can be stored, printed and shared electronically, which eliminates the need for storing large paper drawings.
- 5. DISADVANTAGEOFCAD Power cuts and viruses can be problematic for the computerised system. Industrial versions of the software could be very expensive to buy especially for the startup costs. Traditional drafting skills will be lost as they become unnecessary. Expensive training would be required to use the software, which can be time-consuming and costly.
- 6. ADVANTAGESOFCAM Manufacturing requires minimum supervision and can be accomplished during unsocial work hours. Manufacture is less labour intensive and saves labour cost. Machines are accurate, and manufacturing can be repeated consistently with large batches. Error occurrence is negligible, and machines can run continuously. Prototype models can be prepared very speedily for elaborated inspection before finalising designs for manufacture. Virtual machining can be used to evaluate machining routines and outcomes on the screen.
- 7. DISADVANTAGESOFCAM It requires high initial investment and start-up cost. Machine maintenance is also costly. May result in loss of a workforce with high-level manual skill. To assure proper tooling and set up procedures it needs highly trained operatives and technicians.
