1. Lathe and Milling machine
introduction
Robert, Ethan, Jamie, Joe

2. What is a Lathe machine?
• A Lathe is a machine for shaping wood, metal,
or other material by means of a rotating drive
which turns the piece being worked on against
changeable cutting tools.

3. Safety instructions for using a Lathe
machine?
• •Wear appropriate safety glasses. It may be necessary for others in the area to wear safety glasses too as objects will fly off
the work.
• •Ensure entanglement hazards are removed (e.g. loose clothing, jewellery, etc.).
• •Keep the floor free from obstructions, or slip hazards.
• •Ensure that lathe has a start/stop button within easy reach of the operator.
• •Follow job specifications for the speed, feed and depth of cut for materials being turned. Make sure all work runs true and
centered.
• •Centre-drill work deeply enough to provide support for the piece while it is turning.
• •Secure and clamp the piece being worked.
• •Adjust tool and tool rest so that they are slightly above the centre of the work.
• •Use a lifting device to handle heavy chucks or work. Refer to Materials Handling for additional information.
• •Inspect chucks for wear or damage. Flying pieces can be very dangerous.
• •Remove chuck wrench immediately after adjusting chuck.
• •Use a barrier guard when operating the lathe in semi-automatic or automatic mode.
• •Guard all power transmission parts.
• •Remove all tools, measuring instruments and other objects from saddle or lathe bed before starting machine.
• •Keep all lathe cutting tools sharp.
• •Ensure that the chip and coolant shields are in place.
• •Shut off the power supply to the motor before mounting or removing accessories.
• •Stop lathe before taking measurements of any kind.
• •Use a vacuum, brush or rake to remove cuttings only after the lathe has stopped moving.
• •Keep working surface clean of scraps, tools and materials.
• •Keep floor around lathe clean and free of oil and grease.

4. Dangers of a Lathe machine
• If the chuck key is left in the chuck when the lathe is
started it would be flung across the workshop and
could cause injury.
• Baggy clothing could get caught in the lathe when it is
running.
• Hot Swarf can be thrown off of the lathe at speed.
• If the workpeice isn’t properly clamped down then it
can come flying of the lathe and cause injury.
• If long hair isn’t tied back it could get caught around
the spindle or around the workpeice.

5. What does it do/create?
• A lathe is a machine tool which rotates an
object like wood or metal on its axis to
perform various operations such as cutting,
sanding, knurling, drilling, or deformation,
facing, turning, with tools that are applied to
the object to create an object which has
symmetry about an axis of rotation.

7. What is a Milling machine?
• A milling machine is a tool found primarily in the
metalworking industry. These machines are used
to shape solid products by eliminating excess
material in order to form a finished product.
• Milling machines can be used for a variety of
complicated cutting operations. They are also
used in die sinking, which involves shaping a steel
block so that it can be used for various functions,
such as moulding plastics or coining.

8. Safety instructions for using a Milling
machine
• Wear appropriate safety glasses.
• Ensure that the work piece and cutter are mounted
securely before taking a cut.
• Check that work is mounted squarely.
• Mount work in a vise that is bolted or held magnetically
to the table. Use proper hand tools to make adjustments.
Refer to Hand Tools for more information.
• Move table as far as possible from cutter while setting up
work to avoid injuring your hands.
• Mill the largest surface first.
• Use a vacuum, brush or rake to remove cuttings only
after the cutters have stopped moving.

9. What does it do/create?
• Milling Machines can be used for carving in to
solid materials such as Metal or Wood. It is
designed to withstand big pressures when in use.
• Milling machines can be outfitted with a number
of tool heads to accomplish different machining
needs. Some of these tool heads include cutters,
rounding mills, fluted mills and ball end mills.
Some milling machines have rotating tool ends
that can change depending on the needed task
computer programming communicates with the
machine when to change its tooling.

11. How do they compare?
• Lathe rotates material that you are using, with
the milling machine e.g. steel block stays in
one place and you manually move the drill
piece where you want it to.
