• To properly load a cutting tool into a CNC Lathe, the following steps should be taken:

  1. 1. Inspect the turret and toolholder for any damage or debris. Clean and lubricate it if necessary.

     2. Inspect the cutting tool for any damage or wear. Replace it if necessary.

     3. Verify that the machine is in the proper mode and that the spindle is not rotating.

     4. Unload any toolholders currently loaded in the turret, or move to an open turret position.

     5. Load the new tool into the turret, ensuring it is in the correct orientation

     6. Verify that the tool is securely clamped and has the proper stickout/clearances

     7. Clear any former tool offsets, and enter the new tool's offset values on the control panel of the CNC Mill

     8. Check/Verify the tool offsets are correct

CNC Lathe Workholding Setup

Properly Loading & Locating Parts

• Get with your instructor to see which machine you will be working on this quarter, then on that machine do the following:

  • Load the following tools into the tool changer:

    • (T2 = CNMG432 OD RH IC Roughing Tool)

    • (T4 = VNMG332 OD RH IC Finishing Tool)

    • (T6 = 0.1125" Roundnose OD IC Groove-Turning Tool)

    • (T8 = 0.1125" Squarenose OD IC Parting Tool)

  • Safely & correctly load hard jaws (equally-spaced) to clamp and release a 1.5" diameter round bar

  • Cut & load the following piece of raw stock into the chuck, with the following specs:

    • (STOCK = 1.500" X 4.750" 15-5 PH SS Round Bar)

    • (STICKOUT FROM JAWS = 3.750")

  • Once done, create a "CNC Lathe Operation" Project page on your portfolio website, and upload documentation your progress, including:

    • Pictures(s)/Gif(s) and/or Summaries/Descriptions of:

      • Loading the tools

      • Loading the Chuck Jaws

      • Prepping & Loading the raw Stock in the Chuck

      • Descriptions/summaries of what you did/learned, including any mistakes/learning moments during this task
