1. Introduction
1.1 What is milling ?
Milling is a machine process in which material is removed by rotation multiple tooth cutter. As the cutter rotates each tooth removes a small amount of material from the advancing work for each spindle (rotation) revolution . The relative motion between the work piece and the cutter can in be any direction. Surface having any orientation can be machined in milling.
What is copy milling ?
Milling machine to produce complex shape like cam, die molds ,spectacles profile or any other intricate profile for either piece or mass production requirement are often equipped with copying capabilities through tracer control .A master or a template is used as model to reproduce work piece shape .The co-ordinates of cuter path are determined by tracing template through a stylus or pilot . The tracer control is obtained by one of the following system:
1. Mechanical
2. Hydraulic
3. Electric
4. Optical control (light beam with electric eye sensor)
Copy milling machines with tow axis tracing are equipped with flat template .
Irregular countours , radial cam profile ,or constant depth grooves like that of fixtures can be milled on this machine .This machine is provided with a tracer unit having an manually controlled steering mechanism. In manual operation the worker constantly sense the contract with the template or masterpiece and adjust

3. CONSTRUCTION & WORKING OF COPY MILLING MACHINE
This is manually operated tracer control milling machine which is used for profile cutting of a templates or any easy shape the major parts of machine their construction and working are discussed .
The structure of this machine is depend on function may be divided into following three groups :
Group I : Bed and base upon which the various subassemblies are mounted .
Group II : Box type housing which individual units are assembled like spindle and pinion mechanism.
Group III : Parts that serve for supporting and moving the workpiece like spindle units and fixture for holding the component .

The structure of this machine tool consist of following components
Bed
Table
Column
Spindle Units
Tracer Arm
Main Arm
Pinion Mechanism
Fixture
3.1 BED :- It is the bottom most part of machine on which various other parts are mounted like table, column, arm. The bed of this machine is manufactured from two c-channels on top of which three plates at right angle are welded.
3.2 TABLE:- The table used in this machine is a manually operated antifriction table. It is mounted on top of the bed and is fixed to it by helps of Allen head holts. It has two degree of motion in x and y direction. The table slides between two guide blocks v-grooves are cut in the table and guides. The center of the grooves is slightly offsetted in the table and the bed. The two tables are mounted one on another and at right angle to each other so as to obtained the motion in two directions. In this antifriction ways rolling members (rollers) are inserted between the sliding surfaces, thus changing the nature of friction from sliding to rolling they have following the features.
(1) Low friction as compared to slide ways.
SHREERAM POLYTECHNIC
14
COPY MILLING MACHINE
(2) Uniformity of motion at slow speed due to virtual absence of the
stick slip phenomenon
(3) High stiffness if the rolling member are preloaded and,
The travel of the table ‘x’ and ‘y’ direction are as follows :
1. X direction (lower table) = 200 mm
2. Y direction (upper table) = 160 mm
3.3 COLUMN :- The column of this machine holds the over arm which in turn holds the spindle and spindle driving mechanism. During the operation of the machine, tool the structures are subjected to compound loading and their resultant deformation consist of torsion, bending and tension or compression. Thus looking at all different constraints of loading for clamping at arm and as the load, which is experienced by the column, is less circular section of the column is chosen.
Column piped is welded to the plate perpendicular to its axis the outer face of the plate is faced and the pipe is turned. Four web are welded to the bed with the help of 4 bolts. The column is crome plated so as to increase the appearance and the surface finish of the column, crome plating is done to prevent corrosion.
3.4 SPINDLE UNITS :- The spindle units of the machine hold the cutter in the spindle and satisfies the following requirement :
Rotates at high degree of accuracy, which is determined by radial and axial run out of the spindle nose.
Spindle units must have high dynamic stiffness. The spindle units must be hardened to reduce the wear.
SHREERAM POLYTECHNIC
15
COPY MILLING MACHINE
The deformation of the spindle due to heat transmitted to it by bearing, cutting tools, work piece etc. Should not be larger, as this has an adverse effect on the machining accuracy.
The spindle units must have a fixture, which provide quick and reliable centering and clamping of the cutting tool.
The spindle of machine is guided by the bearing which is turn is press fitted in the housing . The threads are provided on housing to a length of 30mm from the top face . The travel of the spindle is adjustable with the help of s ring which is threaded on the housing . Thickness of ring being 10mm. The total travel of spindle units is max = 45mm ,and min = 25mm.
Rack has been cut on housing surface to length of 95mm with the rack and vertical motion of the tool is obtained as in the case of drilling machine. The assembly as a whole is held in a boss is further welded to the horizontal arm . The length of the boss being 65mm . The housing gets a sliding motion inside the boss .Thus the boss guided the housing assembly as whole.
3.5 TRACER ARM :- A tracer arm of the silver steel is mounted in a elongated bush which is further welded to the upper arm. The gunmetal bushes , which have been press, fitted (one on either end) in elongated of the tracer arm. A ‘y’ shaped plate connects the tracer arm with the spindle through the ring threaded to the housing. This facility the simultaneously vertical movement of the spindle and the tracer arm. A chuck has been threaded to the lower end of the tracer arm to hold the pilots. However for extreme, accuracy and precision collects are used. The operator always constantly senses the contact with the template of master and adjusts the direction of the bios pressure applied to the longitudinal plane.
SHREERAM POLYTECHNIC

COPY MILLING MACHINE
3.6 MAIN ARM :- The upper arm is the most precision part of the machine, as it has maintain parallelity between the column, tracer arm and the spindle. The parallelity between the three parts is responsible for precise and accurate operation of the machine, the achieve this objective two complete holes and one semicircular hole is board in the upper arm. A slot has been machined beyond hole on the end for effective champing the upper arm to the column at right angle.
The boss of the spindle is then welded to the semicircular bore. This assures a perfect/accurate perpendicularity between the spindle axis and the arm. The bush of the tracer arm is then further welded in the small bore.
A small bore has been provided on the arm to accommodate the pinion mechanism. Thus the upper arm of the machine holds the spindle mechanism, pilot mechanism. The main arm itself is mounted on the column as stated.
3.7 PINION MECHANISM :- A pinion is mounted on the stepped shaft, which is turn is mounted on the arm. A space is used to positioned the gear in relation to the rack, which has been machined on the spindle housing. This pinion meshes with rack on the housing. The gear has keyed to stepped shaft to prevent its rotation relatives to the shaft. This pinion is used raised or lower the spindle housing.
The bush no. 4 is fitted inside the bore in the upper arm. It provides a greater supporting length to the rotating spacer and shaft A spring loaded ball mechanism is used to lock the spindle mechanism at a particular depth. The mechanism consist of a spring loaded ball which is fixed inside the head of the head of pinion shaft and the semicircular groove cut in the bush no. 7.

The cutter has three position viz. Top position Intermediate position Final position
Top Position :- The collar provided on spindle housing obtained the top position of spindle , and it is the starting position of cutter.
Intermediate position :- Depending upon the position of the first cut and the thickness of sheet this intermediate position is adjusted .This is obtained by adjusting the position of groove in bush no. 7 by rotating it. This is provided for the initial or rough cutting of profile.
Final position :- The final position is obtained by adjusting the position of ring on the spindle housing . Since the position of groove (for fixing or lens) depends on thickness of sheet and whether the groove is offset from the center.
3.8 FIXTURE :- Depending upon the operation to be performed on the machine the fixture is changed. There are two fixtures mounted on two flat bars at right angle to it and parallel to each other.
The front fixture, which the job or sheet is mounted , consists of a bottom plate on the tope of which the sheet of plastic is mounted. The sheet is positioned with the help of 3 dowel pins or stoppers. This ensures proper position of the sheet. The top plate then clamp the sheet from the top and clamping force is applied with help of the two wing nuts, on of each end. As the cutting force is less the subsequent champing force required is also less. Three set screws with pointed edged are fitted in the top plate such that their pointed edges, protrude from the bottom. This provides additional clamping force on the sheet and also avoids the slighter movement in the sheet while cutting. The rear fixture consists of the plate on the top of which the template is directly mounted. The centre distance between the front and the rear fixture is maintained to 120 mm apart.

There are two cuts in between fixture plates so as to provide space for cutter to move inside the profile. Spring ate fitter in and dowel so as to provide auto lifting of the top plate of fixture. This makes it easy to load and unload the work piece. In this profile of the template is same as that is of the profile of the spectacles.

Design of machine
4.1 Spindle
Material used for spindle=EN8(C-45)
Tensile ultimate=600N/mm Yield=300N/mm2
Torque Calculation:
N=120rpm
Power of motion=1/2HP
=1/2 x 746 Watt
Torque =60P/2X3.14XN
=29.68N-mx1000 = 29.68X10^3N-mm
Design as per ASME code
Tensile strength for all material=0.18 X tensile
=0.18 X 600
=108Mpa
And shear strength of all material=0.35X shear
= 0.35 X 380
=68.8Mpa
As the spindle has no key way
68.8Mpa=(16 x T x1000)/d3
d3 68.8 =16 X 29.68 X 1000
d=19.07=20.00mm
SHREERAM POLYTECHNIC

COPY MILLING MACHINE
Due to manufacturing difficulty and other consideration we have taken the spindle diameter as 20mm at the bearing
We have chosen bearing No.6204 for the spindle. The diameter at which chuck is bearing fitted is the minimum diameter i.e.10mm, which is also quite safe
4.2 .The travel of the table:
The construction of the machine has been explained in the previous topic:
The material used for the table is alluminium
The guide are of anti friction type
The roller ,which have been used are in the cage
Therefore the travel is restricted and is as follows
Let,
Lc = length of cage
l =length of guide way
therefore , total travel =2(L-Lc)
a) For bottom table
total travel=2(L-Lc)
L=230
LC=130
For bottom table total travel=2(230-130)=2(100)=200mm
b) For top table Total travel=2(L=Lc) L=230 Lc=150 =2(80) =160mm
SHREERAM POLYTECHNIC

COPY MILLING MACHINE
The equation is valid for when the roller cage is in the center of the guide ways and the moving members.
4.3 Travel of spindle arm:
Total travel of the spindle arm has been calculated as follows :
1.Lenth of housing = lh=120mm
2.Length of boos = lb =65mm
3.Length of treads on the housing = lt = 30mm
4. Length of ring = lr = 10mm
a) Minimum travel of the spindle housing :
Travel of ring = Tr = lt- lr = 30-10
= 20mm
Minimum travel of the housing = lh - lb – lt =120 - 65 - 30
= 25mm
b) Maximum travel of the housing:
Maximum travel of the housing =lh- lb- lr = 120 - 65 - 10
= 45mm
Therefore , the position of the spindle can be set anywhere between 25mm & 45mm
4 .4 Design of the travel of the pinion and the position of the groove for locking the spindle
Pinion PCD = 29mm
Pinion circumstance = 3.14X 29= 91.106mm
SHREERAM POLYTECHNIC
23
COPY MILLING MACHINE
For the travel of 18mmon PCD
Let Oc be the angle of rotation in radian
Oc X D = 25mm x 180/3.14
= 25/29 x 180/3.14
Oc = 41.49
Hence the pinion has to rotated at an angle of 41.49 from its initial position such that the spindle travels by 18mm downward the groove is cut at this angle from the starting point on the bush in the pinion mechanism.

TESTING OF MACHINE
6. TESTING OF MACHINE PARTS:-
6.1 TESTING OF BASE OR FRAME-
The testing of the body or frame is mainly depends upon the load which the machine is going to take. The legs of the body should be at right angle to ground. And the accuracy of alignment depends on the perpendicularity
Bevel protractor takes this test. Before testing the machine it is kept on surface plate . Then it is leveled by spirit level. Then keeping the bevel protractor on
SHREERAM POLYTECHNIC
62
COPY MILLING MACHINE
surface plate, which is already leveled to ground . Then attached to the protector leg . We proceed for another leg . In this way test the perpendicularly of frame of our copy milling machine.
6.2 TESTING THE FLATENESS OF TABLE PLATE :- flatness of table is very essential in copy milling. Table consists of two directions.
A. Longitudinal direction.
B. Transverse direction.
Measuring instrument:- spirit level.
Procedure:- a spirit level is placed directly On the table for the longitudinal as well
As transverse test. The readings are noted
6.3 PERPENDICULARITY OF COLUMN:- The perpendicularity of column to the base plate is tested i.e. in a plane at 90 to the axis of the spindle. The test is performing by placing the spirit level at one end of the column and the error is noted by taking the difference between the readings obtained.
6.4 TESTING OF OVER ARM:-
INSTRUMENT:- Dial Gauge, Spirit Level.
Procedure:- The over hanging arm is claimed in its extreme extended position. Dial gauge is set to zero position, then moved along the over arm and the deviation from parallelism observed on dial gauge or spirit level.

MAINTENANCE
7.1 MAINTENANCE :-
For smooth sliding movement of base greasing is required.
The milling cutter is required to replace if it get warms out.
The pulleys are replaced if they slip or sometime reconditioned.
The milling cutter is required to be ground or it required to make it true after being periodical used.
It is required to color the equipment periodically to protect from corrosion
SHREERAM POLYTECHNIC
65
COPY MILLING MACHINE
The rack is required to be replace the teeth are damaged.
Fixtures screw should be replace periodically.
The linkages should be welded or replaced as per requirement in warm out condition
7.2 SAFETY PRECAUTIONS:-
Do not touch milling cutter when machine is in operation.

2. Check the quotation supplied by vendors.
3. Determined the most economical process or material to manufacture the product.
4. To determined standards of production performance that may be used to control the cost.
8.2 BASICALLY THE BUDGET ESTIMATION IS OF TWO TYPES :-
1. Material Cost Estimation-
Material For Fabrication Standard Purchase Part
2. Machine Cost Estimation-
8.3 MATERIAL COST ESTIMATION :- Material cost estimation gives total amount required to collect the raw material which has to be processed or fabricated to desire size and functioning of the components .
These are divided into two categories :
Material for fabrication Standard purchase parts
8.4 MACHINING COST ESTIMATION :- This cost estimation is an attempt to forecast the total expenses that may include manufacturing cost apart from material cost . Cost estimation of manufactured parts can be

considered as judgment on and after careful consideration , which includes labor , material and factory services required to produce the required parts .
8.5 PROCEDURE FOR CALCULATION OF MATERIAL COST:-
1. After designing a project a bill is prepared which is divided into categories.
a. Fabricated components.
b. Standard purchased components.
2. The rates of all standard items are taken and added up.
3. Cost of raw material purchased taken and added up.
8.6 LABOUR COST:- it is the cost remuneration (wages, salaries, commission bonus etc) of the employees of concern or enterprises.
Labour cost is classified as :
1. Direct labour cost
2. Indirect labour cost
