1 BASIC TEORY OF COMPLEX MILLING

2 PART OF MILLING (a) Column and knee (vertical), (b) Column and knee (Horizontal)

3 MILLING Turret milling machine of Vertical horizontal

4 MILLING COMPLEX (VIDEO)

5 CLASIFICATION OF MILLING OPERATION
Clasification of milling operation : a) slab milling b) face milling, c) end milling

6 MILLING OPERATION METHODE
(a) Up milling dan (b) Down milling

7 DOWN MILLING Catter simillir with a few catting tool of lathe
Kinds cutter of Horizontal and vertical milling machines

8 MILLING TYPE Column and knee milling machines
Bed type milling machines

9 MILLING TYPE Special purposes. Milling machine with two Spindle
Bed type CNC milling machine

10 CUTTING PARAMETER OF MILLING MACHINES
v = Cutting speed (m/minut) d = Diameter of Cutter (mm) n = Rotation of work piece (rpm)

11 Feeding per toot (ft) and feeding per rotation (fr).
CUTTING PARAMETER Feeding per toot (ft) and feeding per rotation (fr).

12 MILLING CUTTER GEOMETRI
Name of part slab milling cutter

13 MILLING CUTTER GEOMETRI
Name of part slab milling cutter

14 MILLING CUTTER GEOMETRI
Insert Milling Cutter

15 EQUIPMENT AND ACSESSORIES OF MILLING CUTTER
Arbor

16 EQUIPMENT AND ACSESSORIES OF MILLING CUTTER
Offset boring head Hoolding tool (end mill) (b) Holding tool shell end mill.

17 HOLDING WORK PIECE AT MILLING MACHINE
(a) Plain vise, (b) Universal Chuck

18 HOLDING WORK PIECE AT MILLING MACHINE
Dividing Head Fungsi: untuk membuat segi banyak, roda gigi, atauhelix. Meja yang dapat diatur sudutnya dalam beberapa arah Fungsi: untuk alat bantu pengerjaan benda kerja yang memiliki sudut lebih dari satu arah.

19 HOLDING WORK PIECE AT MILLING MACHINE
Line finder Parallel vise stop Line finder is attached.at collet

20 ALAT PENCEKAM DAN PEMEGANG BENDA KERJA PADA MESIN FRAIS
Chuck guard V Blok A set Clem

21 MILLING BASIC ELEMEN Vertical and Horizontal Milling Keterangan :
Work Piece: w = wide cutting (mm) lw = long cutting (mm) lt = lv+lw+ln (mm) a = dept cutting (mm)

22 MILLING BASIC ELEMEN Cutting speed: Feeding per toot: Catting time:
Chips Production speed. :

23 MILLLING WORK PIECE surface/slab milling

24 HOLDING WORK PIECE work piece in the middle of chuck
work piece in periphery chuck Work piece unsupported byparallel Work piece supported by parallel

25 Uppermost work piece laboured by as low as possible
HOLDING WORK PIECE Uppermost work piece laboured by as low as possible Uppermost work piece too high
