Machine Workshop (Room G24)
Level 03 - Machine Certification
The milling machine uses a rotating drill bit to carve out portions of a material which is clamped in place. As opposed to drilling, where the tool is advanced along its rotation axis, the cutter in milling is usually moved perpendicular to its axis so that cutting occurs on the circumference of the cutter. As the milling cutter enters the workpiece, the cutting edges of the tool repeatedly cut into and exit from the material, shaving off chips (swarf) from the workpiece with each pass.

Health and Safety
- The milling machine is a power tool that has the potential to cause serious injury if used incorrectly. Always exercise extreme caution when using the equipment. NEVER touch the drill bit or other moving parts during use. The drill can easily cut fingers and other body parts.
- Familiarise yourself with the emergency stop buttons on the machine. Always turn the machine off when not in use. NEVER leave the machine unattended while in use.
- Ensure the dust extractor gate is opened before use and closed when finished.
- Use push sticks, fences and safety guards wherever possible.
- Ensure material is clamped firmly against the vice before cutting.
- Do not wear loose articles of clothing and/or jewelry when operating the milling machine.
- Do not try and mill too quickly.
- Do not try and mill unclamped materials.
- Do not turn on the machine without checking the location and fitting of cutting bit.
- Do not try to remove jammed pieces while machine is still running.
- Please see workshop staff if there are any issues with the machines operation. Please do not attempt to make any adjustments without prior approval.
- Turn on dust extractor: Turn on dust extractor and open the dust extractor gate.
- Prepare the workspace: Ensure work area is clear and that all settings are correctly set. Place material to be milled in the vice on the machine. The material must be firmly attached and not removed during operations. See a staff member to unlock the machines power.
- Cut material: Cut the material in a controlled and smooth motion. DO NOT rush.
- Shut down and Remove material: Use the mushroom switch to turn off the machine. Remove the material and clear away any dust and offcuts from both the machine and floor. See a workshop staff member to lock the machines power.
- The milling machine is a great tool to use to cut irregular geometries as each euclidean co-ordinate can be controlled individually.
- One advantage of the milling machine is its ability to control the height of the cutting bit independently of the X and Y which makes the milling machine capable of cutting in 3 dimensions.
