Glossary
1 Boring Make (a hole) in something with a tool or by digging.

2 Chamfering Cut away (a right-angled edge or corner) to make a symmetrical sloping
edge.
3 Chuck A chuck is a specialized type of clamp used to hold an object with radial
symmetry, especially a cylinder. In drills and mills it holds the rotating
tool whereas in lathes it holds the rotating workpiece. On a lathe the
chuck is mounted on the spindle which rotates within the headstock. For
some purposes (such as drilling) an additional chuck may be mounted on
the non-rotating tailstock.
4 Cloud Cloud is a term that refers to applications, services or resources made
available to users on demand via the Internet from a cloud computing
provider’s server.
5 CNC Machine Computer numerical control (CNC) is a method for automating control
of machine tools using software embedded in a microcomputer attached
to the tool. It is commonly used in manufacturing for machining metal
and plastic parts.
6 Collet chuck Subtype of chuck that forms a collar around an object to be held and
exerts a strong clamping force on the object when it is tightened, usually
by means of a tapered outer collar. It may be used to hold a workpiece or
a tool.
7 Coolant media Also known as cutting fluid is a type of coolant and lubricant designed
specifically for metalworking processes such as machining and stamping.
There are various kind of coolant media which includes oils, oil-water
emulsions, gels, aerosols (mist) and air or other gases.
8 Datum A fixed starting point of a scale or operation.
9 Die electric A liquid dielectric is a dielectric material in liquid state. Its main purpose
fluid is to prevent or rapidly quench electric discharges. Dielectric liquids are
used as electrical insulators in high voltage applications, e.g.
transformers, capacitors, high voltage cables, and switchgear (namely
high voltage switchgear). Its function is to provide electrical insulation,
suppress corona and arcing, and to serve as a coolant.
10 Document A document management system is a process system designed to track,
management store, manage and control the flow of documents and files. The system
system relies on computer tools that help the digitalization of documents,
efficiency and profitability are gained by allowing a decrease in the use
and storage of paper. The use of document management software also
facilitates the access and editing of documentation with common
technologies such as cloud computing and cloud storage.
11 Dressing A process to dress (that is, slightly trim) the surface of a grinding wheel.
Grinding dressers are used to return a wheel to its original round shape
iii
C259-006-3:2020
(that is, to true it up), to expose fresh grains for renewed cutting action
(including cleaning away clogged areas), or to make a different profile
(cross-sectional shape) on the wheel's edge.
12 Drilling A cutting process that uses a drill bit to cut a hole of circular cross-section
Machine in solid materials. The drill bit is usually a rotary cutting tool, often multi-
point. The bit is pressed against the workpiece and rotated at rates from
hundreds to thousands of revolutions per minute. This forces the cutting
edge against the workpiece, cutting off chips (swarf) from the hole as it
is drilled.
13 Fixture A fixture is a work-holding or support device used in the manufacturing
industry. Fixtures are used to securely locate (position in a specific
location or orientation) and support the work, ensuring that all parts
produced using the fixture will maintain conformity and
interchangeability. Using a fixture improves the economy of production
by allowing smooth operation and quick transition from part to part,
reducing the requirement for skilled labor by simplifying how
workpieces are mounted, and increasing conformity across a production
run.
14 Industrial 4.0 Refers to the concept of factories from the manufacturing perspective in
which machines are augmented with wireless connectivity and sensors,
connected to a system that can visualise the entire production line,
control, and make decisions on its own. It also describes the trend towards
automation and data exchange in manufacturing technologies and
processes which include cyber-physical systems (CPS), the internet of
things (IoT), industrial internet of things (IIOT), cloud computing,
cognitive computing and artificial intelligence.
15 Lathe Machine A machine tool that rotates a workpiece about an axis of rotation to
perform various operations such as cutting, sanding, knurling, drilling,
deformation, facing, and turning, with tools that are applied to the
workpiece to create an object with symmetry about that axis.
16 Machining Various processes in which a piece of raw material is cut into a desired
final shape and size by a controlled material-removal process.
17 Milling The process of machining using rotary cutters to remove material by
Machine advancing a cutter into a workpiece. This may be done varying direction
on one or several axes, cutter head speed, and pressure.
18 Rake angle Rake angle is a parameter used in various cutting and machining
processes, describing the angle of the cutting face relative to the work.
There are three types of rake angles: positive, negative, and neutral.
19 Reaming Widen (a hole) with a special tool.
20 Shank The shank is the end of a drill bit grasped by the chuck of a drill. The
cutting edges of the drill bit contact the workpiece, and are connected via
the shaft with the shank, which fits into the chuck. In many cases a
general-purpose arrangement is used, such as a bit with cylindrical shaft
and shank in a three-jaw chuck which grips a cylindrical shank tightly.
iv
C259-006-3:2020
Different shank and chuck combination can deliver improved

performance, such as allowing higher torque, greater centering accuracy,
or moving the bit, but not the chuck, with a hammer action.
21 Spindle A rod or pin serving as an axis that revolves or on which something
revolves.
22 Subtractive A process by which 2D or 3D objects are constructed by successively
Manufacturing cutting material away from a solid block of material.
23 Tailstock The adjustable part of a lathe holding the fixed spindle.
24 Taper Diminish or reduce in thickness towards one end.
25 Total Indicator The difference between the maximum and minimum measurements, that
Reading is, readings of an indicator, on the planar, cylindrical, or contoured
surface of a part, showing its amount of deviation from flatness,
roundness (circularity), cylindricity, concentricity with other cylindrical
features, or similar conditions.
26 Truing The alignment (and cutting) of a wheel (especially a grinding wheel) such
that its surface is concentric with its axis.
27 Turret Turret is a form of metalworking lathe that is used for repetitive
production of duplicate parts, which by the nature of their cutting process
are usually interchangeable. It evolved from earlier lathes with the
addition of the turret, which is an indexable toolholder that allows
multiple cutting operations to be performed, each with a different cutting
tool, in easy, rapid succession, with no need for the operator to perform
set-up tasks in between, such as installing or uninstalling tools, nor to
control the toolpath.
28 Turning The action or skill of using a lathe.
29 Vise Mechanical apparatus used to secure an object to allow work to be
performed on it. Vises have two parallel jaws, one fixed and the other

1. Introduction
Machining is defined as various processes to cut a raw material into a desired final shape
or sizes either by using a conventional or computer-numerical controlled (CNC) material
removal machines. This document will focus on the Computer Numerical Controlled
(CNC) machining operation and processes using the advanced machining technology up
to this day. It is widely used in the mass production industries due to its capability of
producing a consistent and accurate finished products outcome.
These processes of controlled material removal are collectively known today as

subtractive manufacturing. It is part of the manufacturing process of commonly metal
product but it can also be used on other raw materials such as plastic, ceramic, wood and
even composites. The finished products usually appear in the forms of high value-added
modular components, machine structures, precision engineering parts, sheet metal
fabrication and assemblies.
There are three (3) main principal processes that involved in transforming these raw
materials into the intended shape and form. They are called turning, milling and drilling.
At times there are some additional process which will be required for fine-tuning and this
process falls under the miscellaneous operations.
The industries that utilises this manufacturing and machining technology encompasses
wide range of activities including mould and die, metal stamping, metal casting, surface
engineering, surface treatment and forging. This is a vital industry supporting country’s
industrial development due its linkage to various economic sectors.
1.1. Occupation Overview
A person who specialises in machining operations are called machinist. They are the
competent workers in three (3) principal machining processes namely turning,
drilling and milling. On top of these, there are other operations falling into
miscellaneous categories which include shaping, planning, boring, broaching and
sawing. All of these processes are performed to achieve the desired finished
workpiece that meets the specifications set out by the engineering drawings or
blueprints.
a) Turning operations - Raw materials are rotated as the primary method of moving
metal against the cutting tool. Lathe are the primary tool used in turning
operations.
b) Milling operations - Cutting tools are rotated to bring the cutting edges to bear
against the raw materials. Milling machines are the primary tool used in milling
operations.
c) Drilling operations - Production or refined of holes by bringing rotating cutter

with cutting edges at lower extremity into contact with raw materials. Drilling
operations are done primarily on drill presses or power hand tools.

C259-006-3:2020
d) Miscellaneous operations - Fine-tuning process of a raw materials using a

typical power machine tool such as power hand drill, hand grinder, gear shaper
and planer.
1.2. Rationale of National Occupational Skills Standard Development
This document is a revision of National Occupational Skills Standard (NOSS)

previously developed namely MC-050-3:2015 Machining Operation. The revision
development process is inclusive of mapping the NOSS to compare and align the
competencies according to the current industry needs. The development panels also
incorporate the latest technological advancement in the machining industry as a
benchmark and to sustain this document usage for the next few years to come until it
is due for next revision.
The reviewed NOSS retains its title as Machining Operations and the entry level at
level 2. This NOSS specifically outline the competencies required to perform
machining operations as required by the industry. It can be used as a guideline for
job description, performance appraisal and personnel development. Training centres
can utilise this document as a guideline in developing the curriculum for Malaysian
Skills Certificate (Level 3) in CNC Machining Operations.
The engineering technological advancement in the machining industry is constantly

changing and moving at a very fast paced. This is clearly evidenced with the
announcement of Industrial 4.0 at the national and international level recently. Whilst
the Industrial 4.0 promotes system automation and information and communications
technology application in the manufacturing process, the adoption of computer
numerical control (CNC) machine is vital in order to keep up with the current
industry trends.
Due to this rapidly evolving manufacturing landscape (I4.0) which calls for the
manufacturing firms to re-evaluate their current approaches and strategies to remain
relevant and competitive, this document will provide the cushion impact for the
trainees to be equip and ready with the relevant information and knowledge before
they enter into the working world. This will include the adoption and implementation
of smart manufacturing solutions where advanced hardware are now combined with
advanced software, robotics, sensors as well as data analytics.
The previous NOSS is also reviewed in order to produce the standard framework to
the latest competency standard expected from the current and potential workers of
this field. Machining operations is a specialised skill with meticulous work processes
as to produce high standard quality service or products. The ultimate aims of this
reviewed NOSS is to produce technically skilled workers in machining operations
equipped with the highest level of discipline and work ethics. The Core Abilities and
Social Values & Social Skills modules are designed and embedded in the training
curriculum as to provide the trainee with employability skills. These skills are vital
in preparing them before embarking into labour market.

1.3. Rationale of Occupational Structure and Occupational Area Structure
Based on the Malaysia Standard Industry Classification (MSIC 2008), General

Machinist and Machinist are classified in Section (C) Manufacturing. The 3-digit
code closely match for General Machinist and Machinist is Group (259)
Manufacturing of Other Fabricated Metal Product; Metal Working Service
Activities.
With the latest development in the machining industry technology, the NOSS
development committee has identified three (3) main pillars that falls under this
group namely Machining, Die Making and Mould Making. These pillars represent
the three (3) main work areas which covers metal machining, metal stamping and
plastic mould making. This NOSS specifically covers the occupational area of metal
machining or just plain machining as it is normally called. The entry level for this
NOSS starts at level 2 even though the job title starts at level 1 as general machinist.
This is due to the reason that most of the competencies at level 1 are also performed
at level 2. The proposed Occupational Structure and Occupational Area Structure for
this NOSS are depicted in Figure 1 and Figure 2 respectively in Section 2 and 3.

7. Work Conditions
Typically, Senior Machinist (Level 3) personnel work in a variety of workspace ranging

from small workshops to large factories buildings. This condition is very much depending
on the employer’s organisation size or business scale. Usually Senior Machinist personnel
have to work according to project or production deadline by meeting a daily, weekly or
monthly production quota set forth by superiors. Most of times, in order to meet the project
and production deadlines, they may have to work extra hours such as overtime and shift
work schedule. They may also work either independently or as part of the production team
with a very specific task and machine operations based on the work orders from their
superiors. These personnel mainly operate the machinery for metal working production.
They can be considered as the backbone in the production line as the finished products
produced by these personnel will determine success rate of the production targets.
8. Employment Prospects
According to the report by Malaysian Investment and Development Authority (MIDA),

Malaysia’s manufacturing sector recorded and impressive approved investment of
RM25.4 billion in Q1 2019. This is an increase of 128.8% more than RM11.2 billion
recorded in Q1 2018. Machining industry contributes part of this statistics as it produces
the high value-added modular components, machine structures and precision engineering
parts for the manufacturing industries. 1
The manufacturing projects approved will create 22,970 new job opportunities. The jobs
created include 1,590 electrical and electronics engineers, 710 mechanical engineers and
180 chemical engineers. In addition, the approved manufacturing projects will also require

about 1,710 skilled craftsmen such as plant maintenance supervisors, tools and die makers,
machinists, IT personnel, quality controllers, electricians and welders.2
On top of the promising market outlook, a competent machinist could also be employed
at a vast variety of manufacturing industries including but not limited to oil and gas,
aerospace, shipping, food and beverages, heavy machineries, electrical and electronics,
medical, automotive and etc.
9. Up Skilling Opportunities
There are ample up skilling opportunities for senior machinist. With more advanced
training and experience in a specific discipline of preference, they can be venture into
different manufacturing industries or become an entrepreneur providing machining
product and services to the larger manufacturing businesses.
Senior machinist normally train on the job, working with more experienced colleagues to
learn and develop new techniques and skills. It is essential for machinist to keep up to date
with new developments in the industry, and there are many relevant short courses,
particularly with regard to machining technique and technology relevant to their field of
machining operations.
At the time this document is being developed, there are no specific Senior Machinist up
skilling or value-added courses being offered either at local or international level.
