 +{{section>tools:clearance_template&noheader&nofooter}}
 +
 +====== Tool Specific Instruction ======
 +
 +===== Point out the following tool features =====
 +
 +  * Maintenance Tag
 +  * Basic Milling principals:
 +      * 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.
 +  * Basic Machine Components and Controls:
 +      * On/off 
 +      * Spindle Brake
 +      * Speed control
 +      * FWD/Rev
 +      * Collet draw bolt
 +      * DRO
 +      * Bed
 +      * High/ Low Gear 
 +      * Oil Pump
 +      * Deburring
 +  * X Motion Controls:
 +      * Manual wheel 
 +      * Axis Lock
 +      * Ways
 +      * Power feed
 +  * Y Motion Controls:
 +      * Ways
 +      * Manual Wheel
 +      * Axis Lock
 +  * Z Motion Controls:
 +      * Z-Axis Cranks
 +      * Axis Lock
 +
 +
 +===== 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.
 +  * Hot things - chips, work piece, tools.
 +  * Toxic Fumes - avoid prohibited metals.
 +  * Hot flying debris - use appropriate tools, work holding, and clear work area.
 +  * Fire/Gas Leak - stay vigilant (listen/smell test), use ignition button correctly.
 +
 +===== Allowable Materials =====
 +
 +  * Can name one common material that is safe for use on the mill.
 +  * Can name one material that is not allowed on the mill.
 +
 +===== Safe Setup/Operation/Cleanup =====
 + 
 +  * Demonstrates proper work-holding with vise, clamps.
 +  * Demonstrates proper feed and speed selection. 
 +  * Demonstrates proper cutting tool selection. 
 +  * Demonstrates proper mounting of cutting tool in collet.
 +  * Demonstrates facing, drilling, profile cutting. 
 +  * Demonstrates edge finding. 
 +
 +
 +===== Knowledge and Technique =====
 + 
 +  * Knows and demonstrates proper PPE.
 +  * Demonstrates how to properly use the power feed.
 +  * Demonstrates proper protocol in the event that the machine breaks.
 +  * Demonstrated proper cleanup.
 +  * Demonstrates what to check on if the Mill is making a lot of noise.
 +  * Demonstrates how to change settings to ensure best quality cuts.
 +  * Demonstrates how to properly use the gear speed lever and the speed control.
 +  * Knows the most notable aspect of the edge finder.
 +  * Knows what a boring bar is used for.
