Electric discharge machining (EDM) is a machining process that uses electrical sparks to erode metals. It works by maintaining a precise gap between an electrode tool and a metal workpiece submerged in a dielectric fluid. Repeated electrical sparks are generated to melt and vaporize small amounts of metal from both the tool and workpiece, allowing complex and hard-to-machine shapes to be produced. EDM can machine metals regardless of hardness and without mechanical force, giving it advantages over traditional machining methods for difficult-to-cut materials.
The document discusses ultrasonic machining (USM), which uses high-frequency vibrations and an abrasive slurry to erode material. USM can machine hard and brittle materials by using a vibrating tool to drive abrasive particles against the workpiece. The document outlines the principles, components, process parameters, applications, and advantages/disadvantages of USM. It describes how the tool, transducer, abrasives, and other system parts work together to remove material through brittle fracture caused by abrasive particle impacts. Examples are given of complex features that can be machined using USM.

Non-traditional machining techniques remove material using various energy sources besides traditional cutting tools. They are divided into mechanical, electrical, thermal, and chemical techniques. Non-traditional techniques are needed for hard or complex materials, and can machine intricate shapes and deep holes. Selection depends on the part geometry, material properties, machining capabilities, and cost effectiveness. While more expensive initially than traditional techniques, non-traditional machining offers higher precision, surface finish, and ability to machine difficult materials.
Machinability data systems aim to select the proper cutting speed and feed rate for a machining operation given characteristics of the operation such as the type of machining, machine tool, cutting tool, workpiece, and other parameters besides speed and feed. There are two main types of machinability data systems: database systems which store data from experiments and experience to provide recommendations, and mathematical model systems which go beyond simply retrieving data by attempting to predict optimal cutting conditions through mathematical models.

Study of Manufacturing of Multi-Saddle ClampIRJET Journal
The document discusses the design and manufacturing of a multi-saddle clamp die. Previously, single cavity dies were used to manufacture individual saddle clamps through bending or blanking operations. However, this was an inefficient process. The proposed multi-saddle clamp die allows for multiple clamps to be manufactured simultaneously through bending and blanking operations in the same die, improving productivity. Key requirements for the die design include producing quality products efficiently while minimizing manufacturing costs and scrap material. The methodology involves identifying the problem, collecting information, and developing a solution to design a die that can manufacture multiple saddle clamps in a single cycle through different operations like surface grinding, drilling, tapping, and wire drawing.

PAINT SHOP
The primary concern of this department is cleaning of castings and sheet metal works
and painting them to prevent rust and also to give the machine aesthetic looks.
For sheet metal works the material used are:
CRCA Sheet: Cold rolled closed annealed
HRCA Sheet: Hot rolled closed annealed
The process of painting is as follows:
1. The dust settled on the component is cleaned and the grease is removed using
suitable cleansing agents.
2. The component is then rinsed with soft water
3. De-rusting – there are two ways of doing this:
a. Using phosphoric acid base- this cannot remove black scales
b. Using hydrochloric acid base- this removes the black scales
4. Activation: the metal surface is activated i.e. it is given a charge so as to aid
phosphating such that it adheres to the metal surface.
5. Phosphating: Phosphate coatings are used on steel parts for corrosion resistance,
lubricity, or as a foundation for subsequent coatings or painting. The main types of
phosphate coatings are manganese, iron and zinc.
Most phosphate coatings serve as a surface preparation for other coating and/or
painting. It has many features like electric isolation, excellent adhesion, porosity,
dielectric nature etc.
The whole process is carried out in phosphating tanks.
6. The work is then double rinsed using de-mineralized water.
7. It is then taken to a water drier oven which dries the component.
8. Powder Coating: It is applied as a free-flowing, dry powder. It does not require a
solvent to keep the binder and filler parts in a liquid suspension form. The coating is
typically applied electrostatically and is then cured under heat to allow it to flow and
form a “skin”. The powder may be a thermoplastic or a thermoset polymer. For this
process, the metal is placed on a conveyor which is earthed. The most common way
of applying the powder coating is to spray the powder using an electrostatic gun, or
Corona gun. The gun imparts a positive electric charge on the powder, which is then
sprayed towards the grounded object by mechanical or compressed air spraying and
then accelerated towards the work piece by the powerful electrostatic charge. The
object is then heated, and the powder melts into a uniform film, and is then cooled
to form a hard coating.

For castings the method of liquid painting is used.
1. Blasting the casting so as to remove oil and other contaminants.
2. Primer is applied onto the casting
3. Putty is applied to fill deep holes which give the casting a smooth finish.
4. An epoxy primer is again applied onto the surface
5. Sandering is now done. It is the process wherein the roughening of surface is
carried out using emery paper so as to help the paint adhere to the casting
surface.
6. A masking tape is used to cover machine areas which are not to be painted from
paint deposition.
7. Paint is now applied onto the casting.

MMT oversees all sales and service activities. They get an enquiry from the customer
which is forwarded to the TSG which then makes a quotation depending on what the
requirements are i.e. if it is a standard model or is customized.
This quote is sent to MMT which then sends it to the customer. Once all negotiations
are done the purchase order is given by the customer and the advance payment is finished,
MMT issues an order forwarding format to start the production of the machine to ACE. In case
of customized models separate component drawings are issued and the work begins.
QUALITY ASSURANCE (QA)
It exists to measure, evolve, analyze and feed in the data to facilitate process
improvements in the department. This department deals with:
Inspection of incoming items
Performing tests on machines such as Ball bar test and Laser test
Metrology and calibration of measuring instruments

This is involving the inspection of those components that are manufactured in-house.
11. Internship Report Bindagi, Anuj
ACE Designers Ltd. July 11, 2014
Page 11 of 17
After the manufacture of the first component, the operator inspects it himself and the
dimensions are recorded. Depending on the complexity, there is a secondary inspection
conducted. Inspection is conducted by the operator at every stage of the manufacture of the
component. Upon the completion of all these processes, the results are entered into SAP. After
the complete manufacture of the component, the component is stored in stores.
Items/Components are classified into 3 categories:
1. Most critical items
2. Less critical items
3. Least critical items
For most critical items, almost all components are inspected.
For other categories batch inspection is carried out. The department has a chart stating how
many components are to be inspected per 1000 components and depending on the number
of components complying with the quality standards the whole lot is either accepted or
rejected.
In case of continuous supply of faulty items corrective and preventive action (CAPA) is carried
out.
TOOL ROOM
Tool room is where machining of components takes place.
Principles of work holding:
Wedge action
Taper
Helical
Collets
Pin arbor chuck
2 Jaw chuck
3 Jaw chuck
Chuck
A chuck is a specialized type of clamp used to hold rotating tools or materials.
A self-centering chuck uses jaws, interconnected via a scroll gear, to hold onto a tool or
work piece. Because they most often have three jaws, the term three-jaw chuck without
12. Internship Report Bindagi, Anuj
ACE Designers Ltd. July 11, 2014
Page 12 of 17
other qualification is understood by machinists to mean a self-centering three jaw chuck. The
term universal chuck also refers to this type.
On an independent jaw chuck, each jaw can be moved independently. Because they
most often have four jaws, the term four-jaw chuck is understood. The independence of the
jaws makes the chuck ideal for gripping non-circular and circular cross-sections with extreme
precision. The non-self-centering action of the independent jaws makes centering highly
controllable.
Collets
A collet is a holding device that forms a collar around the object to be held and exerts a
strong clamping force on the object when it is tightened via a tapered outer collar. It may be
used to hold a work piece or a tool.
Each collet generally has only a narrow clamping range, which means that many collets
are required to hold a given range of materials in the chuck, unlike with many other types of
chuck that will generally cover a wide range of sizes.
The space clamping works on the helical principle.

COMPONENT MANUFACTURING DIVISION (CMD)
CMD is a department where singular batch components are manufactured and are
further forwarded to the stores where it gets stored and can be obtained by the assembly unit
as and when required. It is the in-house machining division, where the machinable assembly
items of a machine like bearing housing, saddle, top tables etc. are manufactured. This division
comprises machining centers, turning centers, grinding machines and special lathes to machine
the components.
Here, certain raw materials are brought in from outside. All components are
manufactured according to their process drawings specific to each component. The raw
materials are then processed according to their concerned drawings. A process drawing is
extremely important for the manufacture of any component because it contains the step by
step procedure to machine the component after the proof machining by the vendor and plays a
major role in defining the final dimensional accuracy of the completed component.
In CMD, batch manufacturing of component takes place. This sort of manufacturing
takes immense amount of planning since excess processing will take more lead time. Initially
the batch size is identified and depending upon the criticality of the component a batch size is
decided upon. The number per batch manufactured is specified by the vendor where the
vendor manages the heat treatment process. Excess components are stored for future use.
A specific routing sequence is followed in CMD. A routing sequence is a manufacturing
sequence for any component. Also, it is component specific.
14. Internship Report Bindagi, Anuj
ACE Designers Ltd. July 11, 2014
Page 14 of 17
CMD undertakes a few processes. It has 5 sub-divisions in itself mentioned as follows:
1. Planning: It handles all the planning of the manufacturing of components required by
the assembly division. The software SAP takes care of all the preparation and planning.
2. Manufacturing: The component manufacturing is according to their importance. The
work centers are termed as critical and non-critical based on the quality and quantity of
the operation.
3. Quality Assurance: It exists to measure, evolve, analyze and feed in the data top
facilitate process improvements in the department.
4. Methods: This division provides for process improvements like jigs and fixtures
developments and tooling requirements.
5. Vendor department: It involves inspection of those components that are manufactured
by vendors.
One of the modern concepts used in CMD goes by the name Lean Manufacturing. Using this
concept a lot of improvements are seen it the department.
Just In Time (JIT) concept is implemented for obtaining standard components from in-group
companies.
MACHINE ASSEMBLY
The machine assembly division is one which concerns the assembly of the entire vendor,
bought-out and in-house manufactured items.
The assembly starts off with Axis alignment and Assembly division. The machined
surface is kept clean using kerosene. The guide ways, Linear Motion (LM) or Box/Hardened
Guide-ways are used. LM guide ways are used for higher precision but cannot take deeper cuts
whereas box guides can take deeper cuts but comparatively less precise. Using a spirit-level, the
guide-ways are leveled. The guides are tightened to the Guide-ways such that there is complete
contact with the bed.
The next step in the machine assembly is the assembly of the housing and greasing of
bearings for the re-circulating ball screw arrangement. The ball screw is then assembled on the
machine in between the two rails. This arrangement is used for both the axes. The cross-slide is
now assembled on top of the ball screw arrangement. LM guides are inherently friction-free to
a certain degree.
The headstock is fastened onto the bed. The pulleys are mounted onto the motor shaft
and spindle. The motor is then mounted onto its position. Belts are wrapped around these
pulleys and tensioned to a pre-determined value. This is called belt tensioning.
15. Internship Report Bindagi, Anuj
ACE Designers Ltd. July 11, 2014
Page 15 of 17
Now the axes arrangement is checked for the accuracy of its motion with respect to the
spindle assembly. There are two tests:
1. Primary: A dial gauge is used to check the parallelism between the mandrel and the
cross-slide. A maximum variation of 15 microns is permissible.
2. Secondary: Plane normal to the cutting plane is called Secondary plane. A maximum
variation of 25 microns is permissible.
3. Squareness: The degree of perpendicularity of cross-slide movement with respect to the
spindle axis is referred to as squareness. A special fixture designed by ACE themselves iu
used to check this parameter.
This is followed by tail stock assembly. The assembly of axes, tailstock and motor is called as
Carcass assembly. This is then shifted to the flow line. The flow line concept is one where the
machine is indexed while the work-center is stationary. This helps in belter time-management,
resource planning and improves the overall efficiency of the assembly function. The flow line at
ACE has 8 major station and a 9th idle station. Some of the assembly procedures taking place in
each is as stated below:
Station 1: Guarding Assembly 1
