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
Here are common CAD/CAM interview questions and answers, organized by category, to help you prepare your text or PDF. 1. What is the primary difference between CAD and CAM?
Computer-Aided Engineering involves using software to simulate and analyze how a design will perform under real-world conditions (stress, heat, fluid flow) using methods like Finite Element Analysis (FEA). Part 2: Geometric Modeling Cad Cam Interview Questions And Answers Pdf
A software interface that translates the CAM toolpath data into the specific G-code language required by a particular CNC machine controller.
Defines the object by its edges and vertices. It’s lightweight but lacks information about surfaces and volume. Standing for Standard Tessellation Language , it describes
Controls machine functions (e.g., turning on the spindle, changing tools, or starting coolant). 7. Define "Toolpath" and "Post-Processor."
A slower, precise pass designed to achieve the final dimensions and required surface finish. Part 4: Data Exchange & Formats 9. Why are STEP and IGES files important? Part 2: Geometric Modeling A software interface that
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?
