(4 Hours) (Total Marks : J00
N.B.: (1) Question No. 1 is compulsory.
(2) Attempt any four questions from the rest.
1. {a) Develop a transformation matrix on alignment of vector V = i + j -1- k with the vector K. Draw 10
suitable diagram to explain the process of transformation.
(b) Hnd a transformation which aligns ihe vector V -=* i *+- J * k with the vcc;or N2i - j - k. Ill
2. (a) l;ind the general form of transformation N which maps a rectangular window with x extent 10
to in the x direction and y extent Y%sinin to in the y direction in to a rectangular vicw-port whh x exlenl xvmifl to and y extent Yj,, to Yvmax.
(b) With the help of neat diagrams explain line clipping and polygon clipping algorithms. 10
3. Develop an interactive object oriented program for the design of any of the machine clement like gear, 20 brake, clutch, cam etc.
4. (a) Distinguish clearly between mass, batch and jobbing shop production. 6
(b) () What do you understand by the termextended enterprise'? fi
(ii) Explain Structured Query Language (SQL) with reference to design datuhase. 8
5. (a) Arc there any design circumstances in which concurrent enginnering would not be appropriate ? 10
Why is it particularly appropriate for the development of designs tor products that are mass produced ?
(b) Why do you think small improvements (in a continuous improvement) are a better way to quality 10 than large leaps ?
6. (a) Explain Z-bufTer algorithm and develop a computer program for (he same. 10
(b) (i) Determine the parametric representation of a right circular cvlindcr. 5
(ii) Bxplain any shading algorithm. 5
7. Write notes on tie following : 20
(a) Design for assembly and design for manufacturing.
(b) Bezier curves
(c) 1 VarientT and Generative process planning
(d) Group technology
(c) NC machines and part programming.
