And Answers Pdf - Cad Cam Interview Questions

Defines the full volume of the object. It includes mass, weight, and center of gravity, making it the most "complete" model for engineering. 5. What are Parametric and Non-Parametric modeling?

Dimensions are fixed. Changes require manual adjustment of the geometry without historical relationships. Part 3: Manufacturing & CAM 6. What is G-code and M-code?

CAD (Computer-Aided Design) focuses on creating, modifying, and optimizing a digital 2D or 3D design of a product. CAM (Computer-Aided Manufacturing) uses that design data to control machinery and automate the manufacturing process (e.g., generating G-code for CNC machines).

Standing for Standard Tessellation Language , it describes the surface geometry of a 3D object using triangles. It is the industry standard for 3D printing (additive manufacturing). Quick Technical Definitions

They are neutral file formats that allow different CAD/CAM software to "talk" to each other. IGES is older and primarily handles surfaces; STEP is more modern and preserves solid geometry and metadata. 10. What is an STL file? Defines the full volume of the object

Defines the object by its edges and vertices. It’s lightweight but lacks information about surfaces and volume.

It is the process of managing a product from its initial conception, through design (CAD) and analysis (CAE), to manufacturing (CAM), and finally to distribution and maintenance. 3. What is CAE? What are Parametric and Non-Parametric modeling

A system where a central computer feeds G-code directly to multiple CNC machines.
