Ramping operation.
Continue cycle until required depth is achieved.
After the roughing operation a finishing cut is required to
achieve good surface finish, see page 32.
1. Radially infeed to required depth + 0.2 mm (max 0.75 x insert width).
2. Retract radially 0.2 mm.
3. Turn axially to opposite shoulder position.
4. Retract radially 0.5 mm.
Roughing – recommended machining sequence
In order to generate a flat bottom and high quality on the side of the groove the following
machining sequence is recommended.
Ramping
The ramping method is recommended to
avoid vibration and minimise radial forces
when machining slender components. It also
gives best swarf control and reduces notch
wear in advanced materials.
By using a round insert, RO or RM geom-
etry, the feeding can be done faster, giving an
even and higher productivity.
Ramping, however, does double the number
of cuts required.
