technical information

Selection of indexable inserts and machining parameters at milling.

At the settlement of proper conditions of milling process one should to direct himself with following rules:
1. With the selection of proper milling head ( tool ).
2. With the selection of proper grade and chipbreaker of indexable insert.
3. With the selection of suitable cutting parameters.

1. Selection of proper milling cutter ( tools ).

IV. a). Milling heads with cutting edge angle K = 90 one should to use as half-side milling cutter
r
for medium - rough machining.
- Milling cutter R610...-... ( the catalogue of PAFANA )- for inserts AP..1003... and AP..1604...
- Milling cutter R616...-... ( the catalogue of PAFANA )- for inserts SDKT09T308 SR
- Milling cutter R618...-... ( the catalogue of PAFANA )- for inserts TP..1603... and TP..2204...

b). Milling heads with cutting edge angle K = 75 one should to use for precise
r
and medium - rough machining.
- Milling cutter R626.62....- for inserts SPKN1203.
0
c). Milling heads with cutting edge angle K = 45 one should to use at the less rigid system Machine - Clampig
r
system - Workpiece - Tool system for finishing and medium machining.
- Milling cutter R646...-... ( the catalogue of PAFANA )- for inserts SOKU 1505 AZER, SE..1204....
At milling of surfaces -choosings, one should to choose diameters of milling cutter so that it would be greater
from 20 ÷ 50% of the width of machined element.

2. The selection of proper chipbreaker and grade of indexable insert.

a). Choice of the proper chipbreaker belongs to perform according to recommendations - see
the catalogue of indexable inserts PAFANA - Page No. 319. Mentioned Table permits to execute both the good
choice of the chipbreaker to the definite group of materials and suitable insert geometry of corner.
b). Choice of the proper grade of indexable insert we execute according to classification rule of grades according
to the norm ISO - see the catalogue of indexable inserts PAFANA - Page No 320 and to their destination
to the suitable group of materials.
The description of basic grades of indexable inserts, recommended cutting speeds and groups
of materials -see the catalogue of indexable inserts PAFANA Page No 321-329.

3. Selection of cutting parameters.

Selection of parameters for milling one should to carry into the following way:
a). Selection of cutting depth . a). Выбор глубины резания.

Diameter of milling cutter should be greater about 20% - 50% from width of cutting.
