CAD/CAM are computer applications that help in generating toolpaths that convert machine tools structured as designs to turn into physical parts. CAM is a term used for Computer-Aided Manufacturing or Machining process. CAD or Computer-Aided Design is a software that helps create things by designing and drawing by constructing a model with the help of geometric shapes. After the completion of design using CAD, CAM is required to process convert the part on CAD so that it can be used in machine language.
Considering the important role CAD/CAM plays in designing, many industries use the two software. CAD is used in industries associated with Mechanical Engineering and Designing, Civil Engineering and Designing, Product Designing, Prototype Designing, etc. CAM is mainly required for manufacturing for mechanical components where the CNC machine is used. Companies associated with these industries are always in search of professionals who have the skills and in-depth knowledge of CAD and CAM.
Here are the Best most trending interview questions along with their answers that will help you get a job in 2020:-
Question: What is the CAD system?
Answer: CAD system includes two basic components:
Question: What is the drawing entities? List a few.
Answer: The entities used to create a drawing on CAD are called drawing entities. There are a variety of entities available depending on the requirements. The entities commonly used include point, line, arc, ellipse, circle, polygon, rectangle, etc.
Question: What are drawing utilities? Name a few drawing utilities
Answer: Several functions are used for the creation and storage of drawings. These functions are called drawing utilities. These include screen size, line type, scaling, grid, layers, units, snap, etc.
Question: What do you mean by Editing Commands in CAD? Name a few.
Answer: After creating the first draft, entities of drawings need to be corrected and altered. The same can be done with the help of editing commands. For example move, array, erase, fillet, chamfer, mirror, rotate, trim, copy, scale, etc.
Question: What is Geometric modelling? Name a few Geometric modeling techniques.
Answer: The use of CAD system to create a mathematical description of an object’s geometry is called geometric modelling. This is stored in computer memory and includes creating new geometric models. The various types of geometric modelling techniques used in CAD are two-dimensional modelling and three-dimensional modelling: based on dimensioning; wireframe modelling, surface modelling and solid modelling: based on modelling.
Question: Why did you choose CAD to pursue as a career?
Answer: CAD is the leading designing application as it delivers high productivity in lesser time. It allows for accurate and central process-oriented designing. CAD offers easy modification and effective creation of manufacturing documentation.
Question: What is the difference between 2D and 3D in CAD?
Answer: While 2D modelling helps design flat objects and layouts of buildings, 3D modelling allows conceptualizing real objects by modelling three-dimensional designs.
Question: What are the advantages of Wireframe modelling?
Answer: Wireframe modelling is helpful in many ways. It offers features such as simple construction, less training requirements, less memory space and less manipulation time.
Question: What is CSG?
Answer: The technique of using Boolean combinations of primitives solids to build a part is called Constructive Solid Geometry. In 3D, Boolean operations are addition (+) and subtraction (-).
