3.2.1 What Is Quality?
In manufacturing, a measure of excellence or a state of being free from defects,
deficiencies and significant variations. It is brought about by strict and consistent
commitment to certain standards that achieve uniformity of a product in order to
satisfy specific customer or user requirements
What is the role of a quality department?
Quality management ensures that an organization, product or service is consistent. It has
four main components: quality planning, quality assurance, quality control and quality
improvement. Quality management is focused not only on product and service quality,
but also on the means to achieve it.
Page 18
19. What is 5S?
5S is a system for organizing spaces so work can be performed efficiently, effectively,
and safely. This system focuses on putting everything where it belongs and keeping the
workplace clean, which makes it easier for people to do their jobs without wasting time or
risking injury.
5S Translation
The term 5S comes from five Japanese words:
Page 19
20. • Seiri
• Seiton
• Seiso
• Seiketsu
• Shitsuke
In English, these words are often translated to:
• Sort
• Set in Order
• Shine
• Standardize
• Sustain
•
Page 20
21. 3.3.2 KAIZEN
Kaizen means improvement, continuous improvement involving everyone in the
organization from top management, to managers then to supervisors, and to workers.
In Japan, the concept of Kaizen is so deeply engrained in the minds of both
managers and workers that they often do not even realize they are thinking Kaizen as
a customer-driven strategy for improvement. This philosophy assumes according
Imai that ‗‘our way of life – be it our working life, our social life or our home life –
deserves to be constantly improved‘‘

24. CHAPTER – 04
STUDY OF MAJOR MACHINES
a. Pressure Die casting ( ZITAI):- Die casting is a metal casting process that is
characterized by forcing molten metal under high pressure into a mold cavity. The
mold cavity is created using two hardened tool steel dies which have been machined
into shape and work similarly to an injection mold during the process. Most die
castings are made from non-ferrous metals, specifically zinc, copper, aluminium,
magnesium, lead, pewter and tin based alloys. Depending on the type of metal being
cast, a hot- or cold-chamber machine is used.
Fig. 4(a) Pressure Die casting M/C
The selection of a material for die casting is based upon several factors including the
density, melting point, strength, corrosion resistance, and cost. The material may
also affect the part design. For example, the use of zinc, which is a highly ductile
metal, can allow for thinner walls and a better surface finish than many other alloys.
The material not only determines the properties of the final casting, but also impacts
the machine and tooling. Materials with low melting temperatures, such as zinc
Page 24
25. alloys, can be die cast in a hot chamber machine. The melting temperature also
affects the tooling, as a higher temperature will have a greater adverse effect on the
life of the dies. Material use in this process is Aluminum alloy.
b. Vertical Machining Centre (VMC) : Toshiba Machine Tool offers the highest
quality in the today market. This provide dual opening front door. This ensures easy

34. Eight Disciplines (8D)
what is 8D ?
Problem Solving is a method developed at Ford Motor Company used to approach and
to resolve problems, typically employed by engineers or other professionals. Focused on
product and process improvement, its purpose is to identify, correct, and eliminate
recurring problems
D0: Preparation and Emergency Response Actions: Plan for solving the problem
and determine the prerequisites. Provide Emergency response Actions
D1: Use a Team: Establish a team of people with product/process knowledge.
D2: Describe the Problem: Specify the problem by identifying in quantifiable terms
the who, what, where, when, why, how, and how many (5W2H) for the problem.
D3: Develop Interim Containment Plan: Define and implement containment
actions to isolate the problem from any customer.
D4: Determine and Verify Root Causes and Escape Points: Identify all applicable
causes that could explain why the problem has occurred. Also identify why the
problem was not noticed at the time it occurred. All causes shall be verified or
proved. One can use five whys or Ishikawa diagrams to map causes against the
effect or problem identified.
D5: Verify Permanent Corrections (PCs) for Problem will resolve problem for the
customer: Using pre-production programs, quantitatively confirm that the selected
correction will resolve the problem. (Verify that the correction will actually solve
the problem.)
D6: Define and Implement Corrective Actions: Define and Implement the best
corrective actions.
D7: Prevent Recurrence / System Problems: Modify the management systems,
operation systems, practices, and procedures to prevent recurrence of this and
similar problems.
D8: Congratulate main contributers to your CAR team: Recognize the collective
efforts of the team. The team needs to be formally thanked by the organization.

35. LEARING AND KNOWLAGE
Quality Control
Training: The International Standards Organization acts as a bridge between
the public and private manufacturers. Its primary purpose is to find a consensus
between the needs of the marketplace and the requirements of private businesses.
Quality control inspectors must be familiar with the international guidelines and
regulations established by the ISO; therefore, most distance learning quality
control programs will include extensive coursework covering these guidelines and
their importance.
Statistical Quality Control: Statistical quality control is a technique by which
quality control inspectors examine a statistical sampling of the units produced by a
production process. These units are examined for flaws and inconsistencies, and
inspectors work to gauge the percentage of flawed products in comparison to the
total output and pinpoint where in the process these flaws occur. Since this is a
crucial part of quality control inspection, most distance learning programs will
include a course that covers this process.
Nondestructive Testing (NDT): Nondestructive Testing is a group of techniques
used to evaluate various components of a product without causing damage to it.
Methods of testing include the use of sound, electromagnetic radiation, and X-rays.
NDT is a meticulous and tedious process that requires a great deal of hands-on
training; however many distance learning programs provide a detailed
informational groundwork for the aspiring quality control inspector.
Quality Improvement: This course focuses on customer service components of
quality. Students will study the way that each piece of an organization contributes
to the overall quality of the service or product provided. They will also discover
various techniques to monitor and improve quality.Page 35
36. Interpretation of Technical Documentation: Those in quality control need to be
able to read the technical engineering documents of their products. This course
teaches the common conventions, symbols, and formatting found on these
documents.
Value-Based Quality: Quality is often a value-based assessment. In this course,
the perceived value of a product by the customer is used as the basis on which
quality control can establish a management system
Page 36
37. Quality Glossary :
Coustmer audit
Auditing is the on-site verification activity, such as inspection or
examination, of a process or quality system, to ensure compliance to
requirements. An audit can apply to an entire organization or might be
specific to a function, process, or production step.
Types of audits
• Product audit – An examination of a particular product or service (hardware,
processed material, software) to evaluate whether it conforms to
requirements (that is, specifications, performance standards, and customer
requirements).
• Process audit – A verification that processes are working within established
limits. It evaluates an operation or method against predetermined
instructions or standards to measure conformance to these standards and the
effectiveness of the instructions. Such an audit may:
o Check conformance to defined requirements such as time, accuracy,
temperature, pressure, composition, responsiveness, amperage, and
component mixture.
o Examine the resources (equipment, materials, people) applied to
transform the inputs into outputs, the environment, the methods
(procedures, instructions) followed, and the measures collected to
determine process performance.
o Check the adequacy and effectiveness of the process controls
established by procedures, work instructions, flowcharts, and training
and process specifications.
• System audit – An audit conducted on a management system. It can be
described as a documented activity performed to verify, by examination and
evaluation of objective evidence, that applicable elements of the system are
appropriate and effective and have been developed, documented, and
implemented in accordance and in conjunction with specified requirements.
Page 37
38. FINDING AND SUGGESTION
A WASTE HEAT RECOVER
A waste heat recovery unit (WHRU) is an energy recovery heat exchanger
that transfers heat from process outputs at high temperature to another part
of the process for some purpose, usually increased efficiency. The WHRU is a
tool involved in cogeneration. Waste heat may be extracted from sources
such as hot flue gases from a diesel generator, steam from cooling towers, or
even waste water from cooling processes such as in steel cooling.
SMALL EXAMPLE
Regenerative Thermal Oxidizer (RTO) Systems use a process of applying very
high heat to purify dangerous exhaust air toxic compounds, by oxidizing the
exhaust and destroying the gaseous hydrocarbons and waste volatile organic
compounds (VOCs) at 1500 F and greater oxidation temperatures.
