What is interpolation? State its types. Explain linear interpolation with neat sketch
Definition : When the feed rates of individual axis are not constant and they vary continuously through the move it is called interpolation.
Following are the types of interpolation:
1. G00- Rapid Traverse
2. G01-Linear Interpolation
3. G02-Circular Interpolation(Clockwise)
4.G03-Circular Interpolation (Counter clockwise)

N1 G00 G71 G94 M03 S800 EOB
|
Absolute mode, metric mode, feed in mm/min and spindle start at 800 rpm CW
|
N2 G00 X 10.00 Y 30.00 EOB
|
From starting point (0,0) the cutting tool moves .At rapid feed rate to point 1 with no change In Z coordinate
|
N3 G00 Z 2.00 EOB
|
In Rapid feed rate, the cutting tool moves to a point
|
N4 G01 Z-5.00 F 200 EOB
|
In Linear interpolation ,the cutting tool moves toDepth 3 mm inside the workpiece at feed rate 200 mm/min.
|
N5 G01 X 30.00 EOB
|
In Linear interpolation, the cutting tool moves toPoint 2
|
N6 G01 X 50.00 Y 45.00 EOB
|
In Linear interpolation ,the cutting tool moves To point 3
|
N7 G00 Z 20.00 EOB
|
Tool moves ta a point 20 mm above the job surface, At rapid feed rate.
|
N8 G00 X-10.00 Y 0.00 EOB
|
Move to point X-10.00 to clear the job for loading /Unloading
