   * The spindle must be completely stopped before adjusting or removing work piece
   * After milling is completed, the work piece will have developed sharp burrs which must be removed with a hand file or sandpaper
-====Safe Operating Procedures Review====
+===== Operating Procedures Review =====
-  - Design part using Solidworks or other CAD platform
+  - Program tool paths using a SOLIDWORKS add-in
-  - Using HSM Works generate tool paths
+  - Put tools in tool holders
-    - Each different tool needs to be a separate job as only one tool can be loaded into the Shopbot at a time
+  - Set tool offsets using tool probe
-    - Use 2D and 3D clearing and pocketing to remove the bulk of the material while using "stock to leave" to allow for a finishing pass
+  - Set fixture offset(s) with touch probe (usually G54)
-    - Simulate the toolpaths to verify that the tool will not crash and is cutting in the desired location
+  - Load program
-  - Using the open ended wrench on the spindle flats and the spanner on the collet nut to change out the tool or collet itself if switching shank diameter
+  - Check that tool numbers in program match tools in machine
-  - Home the machine and zero the tool using Shopbot 3, set part zero using the yellow keypad and slowly jogging the tool or edge finder to the part. DO NOT FORGET TO ADD OFFSET OF TOOL RADIUS AND SHIM THCINESS
+  - Check that appropriate fixture offset is loaded
-  - Upload the G-Code into Shopbot 3 under File-> Load
+  - Load stock in the machine
-  - Start program
+  - Proof the part (test the program with air cuts). One easy way to do this is to add a height to the G54 Z value sufficient to make sure that all cuts will be above the top of the part surface.
+  - Use rapid and feed override at the beginning of the program to make sure that the initial Z axis moves are safe. You can also use single block mode
+  - Keep your hand close to the emergency stop in case the program doesn’t do what you expect.
+  - Reset G54 to the correct value.
+  - Run the program for the first time - follow the precautions in step 10 to make sure that nothing unexpected happens. You can adjust the feed rate override as needed.
