*Careful with chamfer operations as the tool will cut in a diagonal past the limits that you identify.
*Parting tool is .161" wide and the zero of the tool is on the right side
*Always reference the Z axis first.
*If the axis doesn't move when you attempt to ref X or Z after a restart, go to the settings tab and make sure that the "Disable reference switches" box is unchecked.
*Make sure the chuck key is never left in the spindle because it will go flying through the protective acryllic.
*Once you have put your stock in the spindle, give it a spin to make sure you have properly secured your workpiece.
*Use 1 and 1/8" hex to loosen quick change tool post holder.

*Fit the chuck key into the chuck and rotate until the chuck is wide enough to accept your 1" piece of stock.
*Take the stop tool and ensure that you have a minimum of 3" of stock sticking out of the chuck.
*Tighten up the chuck with an extra tug, spin the chuck to make sure that the stock is properly secured.
*Take the chuck key and put it on the workbench (it's very dangerous to leave them unaccounted for)

*Remove whatever tool is in the quick change tool post holder and place it on the workbench
*Blow compressed air onto the empty holder to clear all chips and debris
*Load tool 1 (RH turning tool) into the tool holder and secure the tool
*In the computer, click the "main" tab and type in "T01" into the text box that faintly reads "MDI". This informs the lathe that it is cutting with tool 1.
 
3)
*Using the jogger, click the "Z" and carefully move the tool towards your workpiece.
*Take a piece of paper, place it between the tool and the workpiece, and slowly until the paper cannot slide in between the two
*In the center of your screen, where there is a text box to the right of a big "Z", enter the value: 0.003. This is the thickness of the paper
*Do a quick check to make sure that the diameter value is accurate. Jog the machine first in the z direction to clear the workpiece, then click the "X" and jog it until it is close to the diameter of the stock. Read the value listed to the right of the "X" and ensure that it is close to the diameter of your stock.
 
4)
*Now it is time to set up the conversational:
*Click on the conversational tab and select the option "Face"
*Enter "1" into the text box to the right of "T" to tell the lathe you plan to use tool 1 for this operation.
*For this operation, we are going to remove the first 50 thousandths of an inch off of the stock
*In the Z End box, enter the value "-0.050" to tell it how far into the material it will cut
*In the Z Start box, enter the value "0" to tell it you plan to start your cut at the beginning of the stock
*In the Initial X box, enter the value of the diameter of your stock (1")
*In the Final X box, enter "0" to tell the machine to cut all of the way through your cut
*All of the other settings are pre-set by trained ninjas and do not need to be adjusted.
*Click "Post to File" and save the project as your last name in the folder "Lathe 1"
