What is the cutting speed for mild steel?
Cutting speeds for various materials using a plain high speed steel cutter
| Material type | Meters per min (MPM) | Surface feet per min (SFM) |
|---|---|---|
| Steel (tough) | 18–50 | 60–100 |
| Mild Steel | 3–38 | 10–125 |
| Mild Steel (with coolant) | 6–7 | 20–25 |
| Cast Iron (medium) | 1–2 | 6–8 |
What is the difference between cutting speed and feed rate?
Cutting speed is defined as the speed (usually in feet per minute) of a tool when it is cutting the work. Feed rate is defined as tool’s distance travelled during one spindle revolution. 3. Feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish.
What is unit of depth of cut?
Depth of Cut (DOC): The measurement. (normally in inches or millimeters) of how wide. and deep the tool cuts into the workpiece. Speed, feed and DOC work together to. determine the Metal Removal Rate (MRR).
