+====== CNC Metal Mill (Tormach) Clearance ======
+{{section>tools:clearance_template&noheader&nofooter}}
+====== Tool Specific Instruction ======
+===== Point out the following tool features =====
+  * Maintenance Tag
+  * E-Stop
+  * Main Power Switch
+  * Motor Power Switch
+  * Spindle Lockout Switch
+  * Spindle and Coolant On/Off Switches
+  * Spindle speed and direction control
+  * Spindle cabinet, spindle lock, draw bolt
+  * Control computer cabinet
+  * Bed
+  * End stops
+  * Manual Oil Pump
+  * Bed motion when moving in +X direction
+  * Bed motion when moving in +Y direction
+  * Motion when moving in +Z direction
+  * Ways
+===== Describe basic principles =====
+  * Climb vs conventional milling.
+  * Work vs work-holding
+  * Spindle RPM vs Feed SFM
+  * Relative cutting rate of steel (slow) vs aluminum (fast).
+  * Tram
+  * Measuring Equipment (calipers, micrometers, scales or rulers, dial indicators, edge finder.
+  * Types of machine code (GCODE), what a postprocessor is, and how to generate GCODE suitable for the Tormach.
+===== Identify & mitigate common hazards =====
+  * Metalworking when done properly is much quieter than woodworking.
+  * Knows the common causes of noise and which hazards they indicate (vibration, deflection, dull tooling).
+  * Heavy things – tooling, work holding equipment & workpieces.
+  * Sharp things - cutting tools, chips, burrs on work piece.
+  * Spinning things – spindle, axis wheels.
+  * Identify 3 pinch points on the machine; recognize that the machine may move without warning unless locked out.
+  * Hot things - chips, work piece, tools.
+  * Toxic Fumes - avoid prohibited metals.
+  * Hot flying debris - use appropriate tools, work holding, coolant, and clear work area.
+===== Allowable Materials =====
+  * Name 4 common materials allowed on the CNC
+  * Name 1 material that is not allowed on the CNC router
+===== Safe Setup / Operation / Cleanup =====
+The section below may be cleared with no stock material present, but with a tool in the spindle. Demonstrate:
+  * manual on/off of spindle and coolant flow
+  * using the MDI and a GCODE command to move the spindle to a specific position in XYZ.
+  * setting one axis to a specific value (e.g. set X to 0.5")
+  * slow and fast jogging in X, Y, and Z
+  * identifying, then changing the spindle belt configuration (low->high speed or vise versa)
+The section below may be cleared using the "first part" file located on the machine control interface (C:\PCNC3\GCode\FirstPart.nc). Demonstrate:
+  * proper work-holding.
+  * proper feed and speed selection.
+  * proper cutting tool selection.
+  * proper cutting tool installation.
+  * proper zeroing of cutting tool
+  * loading GCODE into the machine control interface
+  * proper zeroing (and ref-ing) of the machine
+  * proper feeds and speeds selection.
+  * proper mounting of workpiece
+  * running a GCODE job
+  * cleaning the CNC and returning the bed to its original state
+  * removing all fixtures, cutting bits, and the collet after use and returning them to storage.
+Additionally, the following rules apply during operation:
+  * Only run GCODE files off the control computer directly and never via USB flash drive or SD card.
+  * **Regularly oil the machine (every 4hrs of operation or 48hrs left idle)**
+===== Knowledge and Technique =====
+Demonstrate:
+  * proper PPE.
+  * how to properly use the motion pendant for fine adjustment.
+  * proper protocol in the event that the machine breaks.
+  * proper cleanup.
+  * what to check on if the Mill is making a lot of noise.
+  * knowledge of when and how to use the coolant system.
