MakerTag System (RFID)
To keep track of which equipment you've been trained on, Bray Lab has implemented a new RFID tracking system that controls the laser cutter and ShopBot CNC router. After you've been trained, our staff will help you set up either an RFID sticker or keychain that will allow you to control these machines.
This is a low-risk zone for team-based project ideation and building. This zone is always monitored by the Bray Lab staff and/or student Shop Assistant and safety training is not required to use this zone.
This zone contains:
- Hand tools and portable drills
- Laser cutter
- CNC Router for plastic and wood
Training for the Laser Cutter or CNC Router can be completed at any time.
Power Tools Zone
To use this higher-risk zone, you'll need to complete the online safety quiz and attend a 4+ hour Power Tools training session (during which you'll complete a project to prove your mastery).
This zone contains:
- Chop saw
- Drill press
- Horizontal band saw
- Jump shear
- Tapping station
- Vertical band saw
Precision Machining Zone
To use this high-risk zone, you'll need to complete either Milling or Turning training with Ben Ginden and request access on a case-by-case basis from the Fabrication Supervisor or Lab Coordinator. The equipment in this zone can cause serious injury.
This zone contains:
- Bridgeport mill
- CNC Lathe
- Haas Mini Mill for metals
- Haas mill for metals
The Power Tools training is a prerequisite for the Bridgeport mill (Milling Intro) and Lathe (Turning Intro) training. See the diagram below.
Training for the CNC lathe and Haas mills are under development and currently not available.
Because serious injury can result from using this zone incorrectly, users must strictly follow the rules below.
Power Tools and Precision Machining Zone Policies
- Users must complete training training and be approved to operate desired machine or tool
- ALWAYS wear safety glasses
- Be sure ALL guards are in place before operating the machine
- STOP the machine before making measurements OR cleaning chips
- Do not attempt to stop a moving or spinning part with your hand, use the brake
- Be familiar with the location of the machine’s stop/E-stop switch or lever controls
- You are the ONLY one who should operate controls
- Always be aware of the direction of rotation and RPM of tool/part being cut
- NEVER reach over or near rotating cutter
- NEVER start a cut until there is adequate clearance for ALL moving parts
- Use care when cleaning machines – use shop vacs and brushes to remove chips
- NEVER clean a machine with compressed air or your hands – chips are SHARP
- DANGER! Serious injury can result from work that becomes loose and spins about on a drill press or milling machine. This dangerous situation is nicknamed a “merry-go-round”.
- Keep the shop clean. Metal scraps should be placed in the scrap bin. Store raw materials and projects. Do not leave any materials or tools on the tables or floor.
- Know the safety requirements of your material. For example:
- Inhaling dust from some exotic wood can respiratory issues.
- Magnesium chips burn with great intensity under certain conditions.
- Stay focused. Do not permit anyone to distract you. No cell phones, ear buds or head phones.
