BIN ABDUL HAMID (19DMA13F2018)INTRODUCTION OF MILLING
MACHINEMilling is themachiningprocess of using rotarycuttersto
remove materialfrom a workpiece advancing (orfeeding) in a
direction at an angle with the axis of the tool.It covers a wide
variety of different operations and machines, on scales from small
individual parts to large, heavy-duty gang milling operations. It
is one of the most commonly used processes in industry and machine
shops today for machining parts to precise sizes and
shapes.KNEE-TYPEUsed for general-purpose milling operationMost
common milling machineMilling cutter mounted on spindle maybe
horizontal for peripheral milling orvertical for face and end
milling, boring & drilling operationsPlain milling machines
have three (3) axes of movement (X,Y,Z)Universal knee-type milling
machine, the table can be swiveled on a horizontal plane
TYPES AND CHARACTERISTICS OF MILLING MACHINE
TYPES AND CHARACTERISTICS OF MILLING MACHINERAM-TYPE MILLING
MACHINECharacterized by a spindle mounted to a movable housing on
the columnIt is to permit positioning the milling cutter forward or
rearward in a horizontal plane. Two common type: universal milling
machine & swivel cutter head ram-type milling machine.
TYPES AND CHARACTERISTICS OF MILLING MACHINEBED-TYPE MILLING
MACHINEWork table is mounted directly on the bedBed replaces the
knee and can move only longitudinallyNot versatile as other types,
but have high stiffness and typically used for high production
workSpindles maybe horizontal or vertical and of duplex or triplex
types (with two or three spindles) for the simultaneous machining
of two or three workpiece surfaces
TYPES AND CHARACTERISTICS OF MILLING MACHINEComputer Numerical
Control (CNC) MILLING MACHINERapidly replaces conventional milling
machinesThese machine tools are versatile and capable of milling,
drilling, boring, and tapping with repetitive accuracyProfile
milling machines have five axes of movement
PARTS AND CHARACTERISTIC OFUNIVERSAL MILING MACHINE
BASIC PRINCIPLES OF MILING MACHINE
Horizontal Milling MachineSpindle motion is assigned Z
axis.BASIC PRINCIPLES OF MILING MACHINEVertical Milling
MachineSpindle motion is assigned Z axis.
CONCLUSIONAfter doing this presentation,we all know and
understanding about types, characteristics, parts and basic
principal of milling machine.We can define what the suitable
milling machine that we can uses for certain type of work on
workpiece.
