Question 1

A cutter tip is initially at X = 10 mm, Y = 20 mm. In a rapid motion, using G00 code, it moves to X = 160 mm, Y =120 mm. The X and Y axes have maximum speed of 10000 mm/min and 5000 mm/min respectively. Operating at maximum speed, what is the time it will take to reach the denstination?

Question 2

Direction: Each of the question consist of two statements, one labeled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answer to these items using the codes given below:

Statement (I): Both sand and metal moulds can be used for centrifugal casting.
Statement (II): In this process, sand moulds are recommended when chilling tendency is to be prevented.
