Machine Rules

The following are a series of safety rules for the appropriate operation of the CNC milling machine. In order to maintain a safe work environment, please follow them strictly. Failure to follow these rules will result in access privileges being revoked.

Safety Rules

  1. Be aware of and follow all Standard Operating Procedures (SOP).

  2. At least one trained operator must be present at all times when the CNC machines are running in addition to the individual(s) who prepared the RhinoCAM file and material. In the event that a job cannot be finished within normal lab hours during which a Fabrication Lab monitor is scheduled,two qualified individuals need to be present, one of which must be a trained operator. If the scheduled monitor is not able to stay later, another monitor or trained operator must commit to monitoring the operation of the machine with the individual user(s) for the extent of the job.

  3.  “After hours” jobs, those that are scheduled outside normal TA hours must be approved by Fabrication Lab Staff in advance. The same “buddy system” outline above must be followed. No “After hours” job may be started after 10pm. Fabrication Lab Staff may restrict certain jobs or operators from accessing the CNC router outside of normal lab hours.

  4. Only trained operators are allowed to run jobs on the Forest Scientific Router, or K2 Router. Only trained CNC router operators are allowed in the router room when the machine is in operation. Trained operators should be in the room only when absolutely necessary when the machine is running.

  5. All machine guards, spindle guards, and adjustable guards must remain between the machine or spindle (as designed) and operator when the machine is in operation.

  6. Whenever the machine is in operation the door between the control room and the equipment room must be closed but freely accessible in case of an emergency.

  7. Eye protection is required to be used when operating the CNC machines. Hearing protection is recommended. Consult MSDS on whether respiratory protection is recommended.

  8. Long hair should be tied back prior to using the tools. Sandals and open shoes are not allowed; only stable closed-toe shoes are permitted. Neckties and bracelets should be removed. Sleeves and other loose clothing should not be worn.

  9. Users are expected to provide their own milling material. The Fabrication Lab will not be responsible for lost or damaged material at any time or under any circumstance. Users are responsible for ensuring the material is free of foreign objects, and that all glues or other adhesives are dry or cured.

  10. Only those tools and types of materials that have been pre-approved for use are allowed. Users must consult Fabrication Lab Staff ahead of time. Fabrication Lab Staff and TAs reserve the right to refuse the use of certain materials, material preparations, and tools.

  11. Users must verify their toolpaths and run a collision check in RhinoCAM.

  12. All .NC files to be sent to the CNC machine must be created on an approved computer with the most recent post processing files installed. All .NC files must be reviewed prior to being run on a CNC milling machine.

 

  • Keep the work area clean. Remove any tools or extra material from the area before operating. Check for foreign objects in or on the material to be machined, such as screws, nails, locating pins, etc.

  • Privileges will be suspended for abusing or damaging the machine.

  • Privileges will be suspended for not cleaning up all excess material after your job has finished.

  • Privileges will be suspended if an individual’s actions contribute to an unsafe environment.

  • Privileges will be suspended for subverting the submittal and review process.

  • The Fabrication Lab Staff and TAs will check for compliance with the above rules.

  • The phone in the shop room can be used to call help. An emergency information chart is located next to the phone.
