Description
End mill working condition calculation method
|
●Cutting speed (linear speed) Calculation VC The distance that a point on the circumference of the end mill blade moves per minute can be calculated using the following formula: |
|
|
V=Cutting speed(m/min) π=3.14 D=Diameter(mm) N=Rotating speed(mm-¹) |
|
●Rotation speed Calculation of Rotationspeed The number of revolutions per minute of the mechanical spindle that holds the end mill can be calculated using the following formula: |
|
 |
N=Rotating speed(mm-¹) V=Cutting speed(m/min) π=3.14 D=Diameter(mm) |
|
● Feed rate Calculation of Feed rate The feed speed of the worktable per minute can be calculated by the following formula  F=Feed rate(mm/min) N=Rotating speed(mm-1) Z=Number of flute f=Feed rate of the flute(mm/1flute) |
|
|
● Feed for teeth Calculation of the Feed ofteeth The distance that a point on the circumference of the end mill blade moves per minute can be calculated using the following formula:  f=Feed rate of the flute(mm/1flute) F=Feed rate(mm/min) N=Rotating speed(mm-1) Z=Number of flute |
|
|
●Working time Calculation of the Working time The time required to cut the workpiece material can be calculated using the following formula  Tc=Working time(min) L=Total working length (Working material length + end mill blade diameterD) F=Feed rate(mm/min) |

◆Special Attention：
1. The following table shows the standard values for side milling. When the tool is grooving, the speed should be 60%~80% of the table below, and the feed speed should be 50%~70% as the standard value.
2. Please use high-precision machine tools and tool holders.
3. Please use air cooling or cutting fluid that does not easily produce smoke.
4. Down milling is recommended for side milling.
5. If the rigidity of the machine tool and the workpiece is poor, vibration and abnormal sound will occur. At this time, the speed and feed speed in the table below should be reduced year-on-year.
6. Keep the tool overhang as short as possible without interference.
