The distance that the tool advances for each revolution of the work is known as ______.
Feed Rate
Explanation:
Drilling:
- Drilling is the production of cylindrical holes of definite diameters in workpieces by using a multi-point cutting tool called a ‘drill.
- It is the first operation done internally for any further operation.
Factors governing drilling operations:
The three factors governing drilling operations are:
- cutting speed
- feed pressure
- cooling method.
Feed:
- The rate at which the drill advances into the material for each revolution of the drill is known as the feed rate and it is expressed in mm/rev.
- The feed rate selection also depends upon the machinability of the metal being drilled.
The rate of feed in drilling is dependent upon a number of factors:
- Finish required
- Type of drill (drill material)
- Material to be drilled (Feed value is lower for hard material)
Factors like the rigidity of the machine, holding of the workpiece, and the drill, will also have to be considered while determining the feed rate. If these are not to the required standard, the feed rate will have to be decreased.
