Quite often in order to start cutting in x-y direction you need to first plunge into the material.
Here is a compliled list of recommendations for different kinds of plunging that works in most if not all cases.
Plunge with center cutting endmill:
- Regular Chipload/Number of flutes , half the cutting speed. (for 3 flute endmill divide normal chipload by 3)
- Ramp Radius (For Helical ramping): .90-.95 of cutter radius
Ramp Angle: Indexed/non center cutting endmills: 1-2.5 degree; Center cutting endmills- Up to 45 deg
Ramp chipload ajustment for 4 flute Center cutting endmills:
- 0-2.5deg=100% of normal feedrate
- 2.5-5deg=75% of normal feedrate
- 5-15deg=50% of normal feedrate
- 15-30deg=25% of normal feedrate
- 30-45deg=5% of normal feedrate
Dont forget to reduce cutting speed for ramping above 5deg by half!
