3. INTRODUCTION TO WIRE DRAWING PROCESSIn the drawing process,
the cross-sectional area and/or the shape of a rod, bar, tube, or
wire is reduced by pulling through a die. One of the oldest
metal-forming operations, drawing allows excellent surface finishes
and closely controlled dimensions to be obtained in long products
that have constant cross sections. In drawing, a previously rolled,
extruded, or fabricated product with a solid or hollow cross
section is pulled through a die at exit speeds. The die geometry
determines the final dimensions, the cross-sectional area of the
drawn product, and the reduction in area. Drawing is usually
conducted at room temperature using a number of passes or
reductions through consecutively located dies. An important
exception is the warm drawing of tungsten to make incandescent lamp
filaments. Annealing may occasionally be necessary after a number
of drawing passes before the drawing operation is continued. The
deformation is accomplished by a combination of tensile and
compressive stresses that are created by the pulling force at the
exit from the die and by the die configuration.

5. METHODOLOGY USED FOR PROJECT
The methodology followed during the course of the project is
shown below:
6.STUDY OF HANDLING TIME OF ACTIVITIES OF WORKERS
1) RM LOADING :
PROCESS DISCRIPTION: This is the process where operators lift
the coils or the RM by the crane from storage area and load to the
Payoff for further processing. This handling process usually takes
time of 8-10 minutes depends on operators efficiency. The
recommended time for handling this activity is 10 minute.
COMPARATIVE STUDY:
DISCRIPTION: The above graph shows the different time taken by
different operators for same process of RM loading. The graph is
based on actual observation during internship.2) WELDING WIRES
PROCESS DISCRIPTION: This is the process where operators join
the wires at payoff for the continuation of wire drawing process so
that workers need not repeat the whole process of passing wires
through each die block. The operators carry out different
activities in wire joining like pointing, welding, finishing and
graphite pasting. The operators ensure the welding is proper and
will not break. Handling this process usually takes time of 20-30
minutes depends on workers efficiency and skills. The recommended
time for handling this activity is 21 minute.
COMPARATIVE STUDY:
DISCRIPTION: The above graph shows the different time taken by
different operators for the same process. The graph compares the
operators on basis of individual activity as well as overall
activity. The graph is based on actual observation during
internship.
3) WIRE BREAK HANDLING :
PROCESS DISCRIPTION: This is the process where operators join
the wire which breaks anywhere in the wire drawing machine while in
process. The operators carry out different activities in wire break
like wire unloading from machine, wire joining pointing, loading
wire again to drum. The operators ensure the welding is proper and
will not break. Handling this process usually takes time of 40-45
minutes depends on workers efficiency and skills. The recommended
time for handling this activity is 40 minute.
COMPARATIVE STUDY:
DISCRIPTION:
The above graph shows the different time taken by different
operators for same process of Wire Break Handling.. The graph is
based on actual observation during internship.
3) PROGRAM CHANGE :
PROCESS DISCRIPTION: This is the process where operators new
program of wire drawing .The operators carry out different
activities for program change in sequence. First the operator
removes the powder and the old wire from the machine. Then he loads
the RM to the payoff and welds the two RM start and end point. The
operator then removes the dies and installs the number of dies of
various sizes as per program and required diameter of wire. This
process takes more time than all other processes. Then the operator
points the wire by pointing machine so that the diameter of wire is
reduced to pass form all dies .the wires is then passed from first
die block and load to roller drum using dog chain. Same way it is
passed through the die blocks as per program to get required
diameter of wire. Then the important step is killing setting. in
this the operator sets the finish pass block in such a way that the
whenever the wire is cut the end of wire is in perfect shape.
Samples are checked to get proper killing setting. After killing
setting wire is attached to coil catcher and wire drawing process
starts. Handling this process usually takes time of 20-30 minutes
depends on workers efficiency and skills and recommended time for
handling this activity is 199 minutes.
COMPARATIVE STUDY:
DISCRIPTION: The above graph shows the different time taken by
different operators for the same process. The graph compares the
operators on basis of individual activity as well as overall
activity. The graph is based on actual observation during
internship.
7.WIRE DRAWING MACHINE 107 IDLE TIME ISSUES
7.1DISCRIPTION: The above graph shows the time taken by the
activities during last six months. The blue bar in graph shows the
time taken by different activities and red line shows the action to
be taken on activities which cuts at 80. To reduce the handling
time and increase the productive time the activities to which red
line cuts at 80 should be focused first as this has major impact
and then rest of activities. Here researcher found that Program
change, Wire break, Operational issue are the major impactors of
handling time so they must be further studied and try to reduce the
handling time of this activities.
7.2 WIRE BREAK ISSUE :
DISCRIPTION: The above graph shows the wire break held at which
block of machine. The blue bar in graph shows the time taken by
different wire break during last six months. This graph shows us
which block of machine have more wire breaks so that we can take
action on it or try to find the problem in particular block for
wire break. To reduce the handling time and increase the productive
time the blocks with major time consuming should be focused for
taking action. Here researcher found that Block no 1, Block no 2,
Block no 3, and Payoff Entanglement are major problems of wire
break in machine no 107.
7.3 WIRE BREAK REASONS :
DISCRIPTION: The above graph shows the wire break reasons of
machine no 107. The blue bar in graph shows the time taken by
different reasons of wire break during last six months. This graph
shows us reasons of wire break in machine so that we can take
action on it or try to find the solution problem. To reduce the
handling time and increase the productive time this problems must
be solved.
7.4 DISCRIPTION: The above graph shows the time taken by
different activities under operational issue during last six
months. The blue bar in graph shows the time taken by different
activities and red line shows the action to be taken on activities
which cuts at 80. To reduce the handling time and increase the
productive time the activities to which red line cuts at 80 should
be focused first as this has major impact and then rest of
activities. Here researcher found that Killing Setting, Powder
Change, Wire Overlapping are the major impactors of handling time,
so they must be focused and try to reduce the handling time of this
activities.
7.5 PROGRAM CHANGE TIME :
DISCRIPTION: The above graph shows the time taken by different
programs of machine 107. These programs are set according to the
diameter of wire to be input and diameter of wire to be obtained.
The above graph is prepared by calculating the recommended times of
all the processes to be carried out during the program change and
overall time required for the particular program can be determined
approximately. The program change time can vary from operator to
operator, depending on his efficiency, skill and experience.
7.6 PROGRAM CHANGE PROCESS :
DISCRIPTION: The above graph shows the time taken by different
activities under the Program Change.
DISCRIPTION: The above graph shows the time taken by different
activities under the Program Change. The graph is based on
observation during internship . In the above graph there is
comparison of actual time taken for program change by operators and
recommended time to be taken by operators. Here the researcher
found that actual time taken by the operators is more than the
recommended this leads to increase in idle time. To get the maximum
productive time this time must be reduced, so the operators need to
work efficiently.
8) WIRE DRAWING MACHINE NO 107 PROBLEMS
1) MAIN ISSUES:1) Crane availability is issue, which causes
delay or leads to increase in idle time. 2) Machine no 107 is has
less automatic control like auto machine stop on wire break. 3)
Payoff entanglement is problem for machine 107.4) Block no 2 in
wire drawing machine gives problem of wire break.
2) POSSIBLE CAUSES FOR THE LONG SETTING TIME :1) Payoff arms
work manually, so operators needs to lift them manually which is
heavy task. 2) System not synchronous i.e. wire feeding and
extraction time delay.3) Long distance to be covered for the
operator in case of any problem (like when wire snaps).4)
Requirement of more efficient personnel.5) Requirement of effective
cooling arrangement due to high temperatures causing wire to expand
while passing through the dies.6) Die not rotating properly.
3) POSSIBLE CAUSES FOR DEFECTS OCCURRING DURING WIRE EXTRACTION
:1) Threading not done properly.2) Die oversize.3) Wire not rounded
properly.
4) PROBABLE CAUSES FOR WIRE SNAPPING :1) Defects in the original
wire.2) Butt-welding not strong enough. 3) Wire gets entangled.4)
Inappropriate die used (when die too small for wire diameter).
9.WIRE DRAWING MACHINE 108 IDLE TIME ISSUES
9.1DISCRIPTION: The above graph shows the time taken by the
activities during last six months. The blue bar in graph shows the
time taken by different activities and red line shows the action to
be taken on activities which cuts at 80. To reduce the handling
time and increase the productive time the activities to which red
line cuts at 80 should be focused first as this has major impact
and then rest of activities. Here researcher found that Program
change, Wire break, Operational issue are the major impactors of
handling time so they must be further studied and try to reduce
9.2 WIRE BREAK ISSUE :
DISCRIPTION: The above graph shows the wire break held at which
block of machine. The blue bar in graph shows the time taken by
different wire break during last six months. This graph shows us
which block of machine have more wire breaks so that we can take
action on it or try to find the problem in particular block for
wire break. To reduce the handling time and increase the productive
time the blocks with major time consuming should be focused for
taking action. Here researcher found that Block no 1, Block no 2,
Block no 3, and Payoff Entanglement are major problems of wire
break in machine no 107.

SUGGESSIONS
1) Lunchtime could be utilized for cleaning and lubricating
machine and machine parts to ensure longetivity.2) M.M.D and E.M.D
work of regular maintenance should be performed during long
operations like program change3) SMED if implemented can reduce the
handling time and can lead to increase in productive time.4) DIE
SET should be directly changed instead of removing it and changing
die in it, this will result in saving the time of handling and
result in increase of productive time .5) Payoff should be
installed with hydraulic jacks as the arms are heavy and need to
lift them manually to load coils.6) Crane should be utilized
alternatively for coil loading, coil catcher unloading as it is
used for both the 107 and 108 machine.7) A wire straightness
apparatus (like the one having bubble using the centre of gravity
principle) could be used to give the straightness. The existing
method used is very crude and non-scientific.
