During a period of erosion and sedimentation, grains of sediment are continuously building up on top of each other, generally in a water filled environment. As the thickness of the layer of sediment increases, the grains of the sediment are packed closer together, and some of the water is expelled from the pore spaces. However, if the pore throats through the sediment are interconnecting all the way to surface the pressure of the fluid at any depth in the sediment will be same as that which would be found in a simple colom of fluid. The pressure in the fluid in the pores of the sediment will only be dependent on the density of the fluid in the pore space and the depth of the pressure measurement (equal to the height of the colom of liquid). it will be independent of the pore size or pore throat geometry.

Introduction of green concepts in machining operations is being envisaged by introducing different echo
friendly cooling systems in the modern machine shops. The role of cutting fluids usage in metal cutting is
predominant as it influences the surface quality and production cost. The current work mainly focuses on the
study of chip tool interactions viz. contact pressure, temperature and chip flow pattern on the rake surface in
plain turning operation for different cutting parameters without any cooling medium and analyze the influence
of high pressure air jet as the cooling medium on the chip tool interactions like contact pressure reducing the
tool wear, cutting temperatures thereby increasing tool life.
Experimental Approach of CNC Drilling Operation for Mild Steel Using Taguchi...IJMER
Drilling is the most common (multi-point) cutting technique targeted for the production of
small-diameter holes. Hole making is among the most important operations in manufacturing, and
drilling is a major and common hole-making process in components. Productivity can be interpreted in
terms of material removal rate in any machining operation. It is, therefore, essential to optimize quality
and productivity simultaneously. Mild steel are soft, ductile, easily machined and is extensive used us a
main engineering material in various industry such as air craft and aerospace industry. The Taguchi
method is applied to formulate the experimental layout to ascertain the Element of impact each
optimum process parameters for CNC drilling machining with drilling operation of mild steel. A total of
27 experimental runs were conducted using an orthogonal array, and the ideal combination of
controllable factor levels was determined for the material removal rate, time of machining and
circularity has been measured. Design optimization for quality was carried out and single to noise ratio
and analysis of variance (ANOVA) were employed using experiment result to confirm effectiveness of
this approach.
Study on A Damping System for the Toolholder in a Turning Processinventionjournals
In the turning process, vibration of the toolholder significantly affects the surface roughness. This study introduces an application of a damping system for reducing toolholder vibration and improving the surface quality of the part being machined in the turning process. The damping system is designed with an object mass and two springs, and it assembles the toolholder using two damping designs. After assembly, the toolholder is used for machining the workpiece with a cutting length of 60 mm, cutting depth of 0.5 mm, velocity of 0.05 mm/rev, and spindle speed of 1000 rev/min. For Design 1, the result shows that when the object mass B (11.83 g)is used and the spring constant is increased from 400 to 2800 N/m, the vibration angle dR decreases from 0.22331º to 0.04632º; however, when the spring constant continually rises to 3733 N/m, the vibration angle increases to 0.10273º. When using Design 2, when the spring constant increases from 400 to 500 N/m, dR reduces to 0.122º. Moreover, Design1 shows better stability than Design 2 with different object masses and spring constants. Object mass B is selected for evaluating the effect of the damping system on the surface roughness. The results show that the surface roughness varies from 0.925 to 1.169 μm and from 1.22225 to 0.84225 μm with Design 1 and 2, respectively.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

2. DRILLING DEFINATION
Drilling is a process of making hole or enlarge a
hole in an object by forcing a rotating tool called
drill.
When
a drill is cutting it has to overcome the
resistance offered by the metal and a twisting effort
is necessary to turn it. The torque required to
operate the drill is dependent upon various factors,
but for most of the practical purposes, the relation
between the torque, the diameter of drill and the
feed has found to be most satisfactory, based on
experiment results.
4. WHY PARAMETERS MEASURMENT AND
OPTIMIZATION
Real time optimization of drilling process
parameters during drilling operation for obtaining
maximum drilling rate as well as minimum drilling
cost, to get high productivity and high MRR by
changing process parameters such as drilling
diameters, cutting speed and feed rate.
For also improve drilling performance like tool life,
material removal rate.
5. AFFECT OF PARAMETERS
The relationships between the cutting force signals
and drill wear as well as other cutting parameters
including spindle rotational speed, feed rate and
drill diameter were established by lots of
experiments.
The tool wear can be estimated knowing the thrust
force, feed per revolution and drill diameter.
The temperature of cutting edge increases with the
increase of spindle speed (cutting speed) and feed
rate.
6. coolant can perform roll for reduction tool temperature,
thrust force, surface roughness.
Amount of metal remove is function of speed and feed.
Feed is varies from 0.05mm to 0.35mm per revolution
and it’s variation is depends on hard and soft material.
Wear is thought to occur from chemical reactions in the
contact zone between the tool and the work piece.
Precise measurements of tool dimensions indicated that
the wear was concentrated at the tool center region and
at the intersection between the conical and cylindrical
regions.
7.
Cutting speed:
The cutting speed in a drilling operation refers to the peripheral speed of a point
on the surface of the drill in contact with the work. The cutting speed (v) may be
calculated as :
v=(pi*d*n)/1000 m per minute.
Where,
d is the diameter of the drill in mm
n is the rpm of the drill spindle.
Feed:
The feed of a drill is the distance the drills moves into the work at each revolution
of the spindle. It is expressed in mm. the feed may also be expressed as feed
per minute. The feed per minute may be defined as the axial distance moved by
the drill into the work per minute. The feed per minute may be calculated as:
Sm = sr × n
Where,
Sm = feed per minute in mm.
Sr = fee per revolution in mm.
n = rpm of the drill.
8.
Depth of cut:
The depth of cut in drilling is equal to one half of the drill diameter. The depth of
cut (t) may be expressed as :
t =D/2 mm
Machining timing in drilling:
T=L/(n* Sr ) min.
Where,
n = r.p.m of the drill
Sr = feed per revolution of the drill in mm.
L = length of the travel of the drill in mm.
T = machining time in min.
L = l1 + l 2 + l 3 + l 4
Where,
l1 = length of the work piece
l2 = approach of the drill,
l3 = length of the drill point (0.29d),
l4 = over travel
9. FIELD WORK
As per availability of measuring instruments which
is required for parameters measurement We have
to do experimental investigation for drilling process
and optimization it’s parameters.
Force, torque, Feeds rate, Spindle Speed, Cutting
speed, power supply.
Taguchi method is utilize while investigation for
higher precision at lower experimental operations in
our project.
