Strengthen Your Quality System Part II
Last month we discussed the importance of Functional Size/Diameter and how to inspect it.
This month we’re going to dive into the next two important inspections: Pitch Diameter and Lead.
Step 2: Pitch Diameter
Gagemaker pitch diameter gages, commonly known as ball PD gages, verify that your part is within allowable tolerances. Improperly sized pitch diameters compromise the load capacity of your threaded components. The ball pitch diameter gages indicate the pitch diameter size of the product’s external and internal threads. The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads. Setting dimensions for the pitch diameter gages are provided by the TDWIN™ Thread Disk software.
After zeroing the external Pitch Diameter Gage (“Ball PD Gage” or PD-8000 Series), place the fixed ball contact onto an external thread. Use lower contact as a pivot while carefully seating the moveable contact point ½ pitch up the helix. Sweep back and forth for largest reading.
The internal PD gage (PD-6000 Series) inspects internal parts – an impossibility with thread wires.
After zeroing gage, retract lever and place moveable contact point into thread at the 6 o’clock position. Apply a little pressure and trace the thread to the 12 o’clock position. Release lever and lower the fixed ball into the respective thread. By sweeping the gage, note the largest reading and verify the dimensional size.
Thread Lead is one of the most important thread elements and directly affects a part’s functional size. Lead error is most commonly generated by manual and CNC lathes not cutting properly. Therefore, it’s important to take measurements at the locations where the most lead error typically occurs. These readings help detect machine tool error and worn lead screws on your lathe.
Lead gages inspect both internal and external lead on a variety of thread forms.
Zero the Lead Gage on the appropriate setting standard. It’s important to take measurements at locations where the most lead error typically occurs. Check both external and internal lead on the first fully formed thread, about 360 degrees from where the machine tool first touches the part. Inspect the next adjacent thread, and finally take a third measurement on the same axial plane near thread end, close to where the tool pulls out. These multiple readings detect machine tool error and worn lead screws on your lathe.
