1

1a. Cut Materials using Saws and Abrasive Discs

1.1

Work safely at all times, complying with health and safety and other relevant regulations and guidelines

1.2

Use two of the following types of cutting equipment:

• machine saw

• band saw

• hand held portable abrasive disc

• radiac abrasive disc

1.3

Ensure that the equipment is fit for purpose and used safely by carrying out all of the following:

• selecting the appropriate equipment/machine for the operation being performed

• checking that machine guards and safety devices are in position and function correctly

• checking that cutting discs/blades are in a serviceable condition (sharp, and free from damage or chips)

• isolating the equipment from its power supply whilst changing blades or discs

• using the equipment safely and correctly and only for its intended purpose

1.4

Confirm that the machine is set up and ready for the machining activities to be carried out

1.5

Manipulate the machine tool controls safely and correctly in line with operational procedures

1.6

Carry out all of the following cutting and shaping activities:

• straight sawing

• abrasive disc cutting

• contour shaping using saws

1.7

Cut and shape components which contain all of the following features:

• straight parallel cuts

• square cuts

• curved contours

• angled/mitred cuts

2

1b. Cut Materials using Saws and Abrasive Discs (continued)

2.1

Cut and shape three of the following forms of material:

• flat plate

• solid bar (square, round, hexagonal etc)

• rolled sections (angle, channel, RSJ )

• pipe/tube

• rail section

• non-ferrous material

2.2

Produce components to the required quality and within the specified dimensional accuracy

2.3

Produce components that comply with all of the following quality and accuracy standards:

• material dimensional accuracy is within specification tolerances

• cuts are square, clean and free from excessive burrs

• angled cuts are within specification requirements

2.4

Carry out quality sampling checks at suitable intervals

2.5

Deal promptly and effectively with problems within their control and report those that cannot be solved

2.6

Shut down the equipment to a safe condition on conclusion of the machining activities

3

2a. Know how to Cut Materials using Saws and Abrasive Discs

3.1

Explain the specific safety precautions to be taken when working in a fabrication environment and when working with power operated saws and abrasive disc cutting machines (statutory requirements, risk assessment procedures and relevant requirements of HASAWA, COSHH and Work Equipment Regulations; safe disposal of waste materials)

3.2

Describe the personal protective clothing and equipment to be worn when carrying out the fabrication activities (leather gloves, eye protection, safety helmets, etc)

3.3

Explain the safe working practices and procedures to be observed when working with the machines (including emergency shutdown procedures)

3.4

Explain the correct methods of moving or lifting heavy plate or rolled sections

3.5

Describe the hazards associated with fabrication work and cutting operations (such using dangerous or badly maintained tools and equipment; airborne particles; hot metal; burrs and sharp edges), and explain how they can be minimised

3.6

Explain how to obtain the necessary drawings, specifications and work instructions

3.7

Explain how to extract information from engineering drawings and related specifications (to include symbols and conventions to appropriate BS or ISO standards in relation to work undertaken)

3.8

Explain how to interpret marking out conventions (cutting lines, centre lines, etc)

3.9

Describe the range of machine saws available (such as power hacksaws, circular saws and bandsaws)

3.10

Describe the abrasive cutting equipment available (to include hand held portable machines and bench type radiac cutting machines)

3.11

Explain the selection and fitting of abrasive cutting discs; cutting disc identification markings, and how to identify the correct type of disc for the type of material being cut

4

2b. Know how to Cut Materials using Saws and Abrasive Discs (continued)

4.1

Explain the statutory regulations regarding the fitting and use of abrasive discs

4.2

Explain the material cutting characteristics and process considerations to be taken into account when cutting materials

4.3

Describe the use and care of tools and equipment (such as checking that trailing leads, plugs and sockets are in a safe and usable condition)

4.4

Explain the use of safety screens to protect other uses from flying sparks whilst using abrasive cutting discs

4.5

Explain the importance of ensuring that machine guards are correctly fitted and positioned before using the equipment

4.6

Explain how to set and adjust power saws for the various operations being performed

4.7

Explain the importance of using tools or equipment only for the purpose intended; the care that is required when using the tools or equipment; the proper way of preserving tools or equipment between operations

4.8

Describe the things that can go wrong when cutting materials using saws or abrasive discs, and explain how these can be avoided

4.9

Describe the inspection techniques that can be applied to check that shape and dimensional accuracy is to specification and within acceptable limits

4.10

Describe the extent of their own authority and explain whom they should report to if they have problems that they cannot resolve

4.11

Explain the reporting lines and procedures, line supervision and technical experts
