4. SAFE WORKING PRACTIC ES
Always wear safety equipment provided:
 Safety Glasses

 Overalls (done up to neck)

 Safety Boots (laces tied)

ALWAYS ensure that long hair is tied back or covered

ALWAYS remove Jewellery - rings, bracelets etc.
(They may get caught in the machine or on swarf)

ALWAYS keep aisles free from obstruction - ensure that exits can be reached safely

ALWAYS keep work area clean and tidy - Avoid slips trips and falls.
Correct manual lifting techniques
The human spine is not a very efficient weight lifting machine. If it is subjected to heavy strain, or
incorrect lifting techniques are used, the lumbar discs may be damaged, causing considerable pain.
Before attempting to lift a load:
 Size up the load — if it is obviously too heavy or bulky for one person to handle, ask for
assistance.
 Even a light load can be dangerous if it obscures vision.
 Move all movable objects which could be obstructions to a safe place.
 Ensure safe area to store load

7. 7




Check before using a Hacksaw

The blade must not be twisted.
There must be no blunt or broken teeth.
The teeth must be facing the direction of cut.


Bench




































Check before using a file
A file must always be fitted with a
handle as without it can easily penetrate
the hand
Check before using a hammer

A hammer must always be fitted with a handle
that is free from cracks and splinters.
The head must be firmly fixed to the shaft.
Check before using a bench drill

Guards must always be used.
Work pieces must always be clamped securely
to the table before drilling.

Long hair MUST be tied back
Safety glasses MUST be worn

Milling

1. Always wear personal protective equipment (PPE.)
2. Never place your hands near a rotating cutter.
3. Always rotate the spindle clockwise.
4. Always isolate machine when changing a tool holding device.
5. Place in low gear to change cutters.
6. When in low gear, turn spindle switch to reverse.
7. Ensure quill is in the home position with lock tightened when milling.
8. Always tighten vice sufficiently.
9. Do not remove anything from the cutting surface with the spindle running.
10. Always adjust spindle speed with the spindle not running.
11. Never leave a spanner attached to the of the draw bolt.
12. Do not "climb mill”
13. Always use a parallel strip if a flat face is not available,
14. Clean vice and de-burr a new piece of steel to reduce risking cutting hands
15. Do not remove work from vice until all operations are completed.

9. 9




Lathe Turning
Check:
 Coolant switch is OFF & tap is turned off and pipe pointing downwards
 Chuck is clear of all tooling and tool holders
 Work piece is tight in chuck and the chuck key removed
 Guards are in position and in good working order
 All stop buttons and devices are in good working order
 Tools are in good condition and firmly clamped
 Chuck is rotating in correct direction

NEVER leave chuck key in chuck ALWAYS remove immediately after use.
NEVER leave tools or equipment on top of guards or on slide ways
NEVER handle swarf with bare hands. ALWAYS use gloves or hooks.
NEVER Change speed while chuck is rotating
NEVER Change spindle direction while chuck is rotating
NEVER Change feed while chuck is rotating
ALWAYS put swarf and waste material in the appropriate container.
ALWAYS isolate machine when:

 Changing holding devices (also use chuck board to protect bed ways)
 Doing any manual operation (Tapping or die threading)
 Clocking work using D.T.I.

When using a drive plate ensure tooling will not foul the carrier or drive pegs at the
end.

When using a faceplate ensure tooling will not foul any clamping at the end of the
turned travel.

5. CNC GENERAL NOTES
Definition of numerical Control

Numerical control is a term used to describe the control of machine movements and various other
functions by instructions expressed as a series of numbers and initiated via an electronic control
system.

Computer numerical control (C.N.C) is the term used when the control system includes a computer.
The control may be an integral part of the machine or a freestanding unit.

Application of Numerical Control

Numerical control can be applied to a wide range of manufacturing processes such as metal cutting,
woodworking, welding, flame cutting and sheet metal forming. Popular engineering applications are
milling, turning, drilling and tapping.

Advantages of Numerical and Computer Numerical Control Systems

CNC controlled machine tools offer several advantages over other types of control systems. The most
important advantages are as follows.

Reduced set up time: Modern control systems are quick and easy to program. Programs can be
edited / modified to correct any errors in minutes.

Reduced tooling costs: Complex forms and profiles can be produced using standard/single point
tools eliminating the need for costly tooling that is dedicated to only one component.

Flexibility: Programs can be stored and loaded when required, and as the tooling used is, with the
occasional exception standard, change over down time is kept to a minimum.

Types of NC machines
Numerically controlled machine tools have two modes of operation:

Point-to-point: Where such operations as drilling, boring, tapping etc. require the cutter axis and work
piece to be placed at a specific fixed relative position and to remain there while the cutter does its
work, they are described as POINT-TO-POINT controlled machines.

Point-to-point control is often for rotary tables where the change of position is angular. Other
operations, such as milling, require motion of the work pieces with respect to the cutter while the
cutting operation is taking place. When the relative motion is always a straight line, such as straight
line milling, point-to-point control is adequate.

Point-to-point control requires the dimension to be given to the machine tool as a series of co-ordinates
(required positions) for each of two slides and sometimes also for the height of the cutting tool.

Continuous path or contour control: In profile milling operations the relative motion is often a
curved path. The control system needed for such an operation is known as CONTINUOUS PATH OR
CONTOUR CONTROL.

Continuous path control machines can also be used for point-to-point
work but it is usually uneconomic to do so when a point-to point
machine is available. Continuous path machines are too productive to
use for point-to-point purposes.

Part Programming

The expression ‘part program’ often causes confusion, since part is often thought to mean something
which is not complete. However when used in the context of part programming or part program, the
program is complete. The word part means component.

Machine Axis Designation

The machine axes, or planes in which the machine moves, are each identified by a letter: X, Y and Z
on a milling machine and X, Z for a lathe. Z axis movement are always along the line of the rotating
spindle.

Preparatory Functions

Preparatory functions, known as G codes, are used to set the conditions for, and the control of
machining operations. The functions are identified by the letter G, followed by 2 digits. For example
when G21 is called the machines measuring system will be in metric, G01 would be called to move the
machine table or cutting tool in a straight line at a specified feed rate. Many G codes are standard
across a range of machine tools however reference to a specific machine manual is always valuable,
as code designation may vary depending on make and type.

Many G codes are known as MODAL and once called remain active until cancelled, for example G40
will cancel G41 and 42. A NON-MODAL G code is only operative in the block (line) of code it is called,
an example of which is G04 dwell.

Miscellaneous Functions

Miscellaneous or management functions are known as M codes. They are used to control functions
that support and manage the machining operation. The functions are identified by the letter M and 2
digits. M code designations do vary depending on machine make and type so REMEMBER WHEN
WRITING A PART PROGRAM, ONLY ONE M CODE CAN BE CAL LED PER BLOCK (LINE).
