INTRODUCTION TO CNC - Quiz

1) What is the basis of absolute co-ordinate point?

Based on the last point entered Based on the origine(0,0) Based on the work end point Based on the tool geometry only

2) What is the basis of incremental co-ordinate system?

Based on the origin Based on the tool geometry Based on the last point entered Based on the tool nose radius

3) How the points are marked in polar co-ordinate system?

Pole as 'O' and polar axis as 'L' angle Pole as X and axis as Y Pole as Z and axis as C Pole as B and axis as C

4) Which letter the origin indicates in co-ordinate geometry?

By letter 'O' By letter 'X' By letter 'Y' By letter 'B'

5) How the co-ordinate system specifies each point uniquely in a plane by?

In the direction of origin only In longitudinal direction In cross sectional direction only A pair of numerical coordinates
