Frequently Asked Questions
Q1: What is the role of computers in manufacturing?
A1: Mainly, it is classified into two types.
One, computer monitoring and control of the manufacturing process. Here, computer is directly interfered with the manufacturing process for mainly monitoring and control functions. For example, chemical processing industries
Second, manufacturing support applications that deals with the preparations for actual manufacturing and post manufacturing process. All support functions are included for the completion of the manufacturing operations. Example, usage of computers to develop the geometric model in 3D form.
Q2: What is CAD and its advantages?
A2: Computer Aided Design (CAD) utilises computer as a tool for all the functions which are involved in the design process. Advantages of CAD are,
– CAD is accurate and more faster than the conventional methods
– Available construction facilities in CAD would make the job of developing the model and associated drafting an easy task.
– It is possible to manipulate various attributes, dimension and distances of the drawing elements under CAD
– Professional CAD packages provide 3D visualization capabilities so that when the designers can see the products being designed from several different orientations
– Modification of a model is east and would make the designer's work simple to take care of any future requirements.
Q3: What are the applications of computer designing?
A3: – Modelling of any design
– Engineering analysis and design
– Evaluation/examination of prototype through testing and simulation
– Draft and designing documentation
Q4: What are the Advantages and disadvantages of b-rep?
A4: Advantages of b-rep include,
– They are appropriate to construct solid models of unusual shapes
– It is relatively simple to convert a b-rep model to wire frame model
Disadvantages of b-rep
– B- rep Requires more storage than any other
– They are not very suitable for applications like tool path generation
– They have Slow manipulation
