Calibrating a Dashboard
Open full view...Categories: Troubleshooting MillMax
The vast majority of the time Dashboards are correct, but occasionally you may come across these two possible scenarios. The Dashboard on the left shows red where the customer is currently running stable without chatter. The Dashboard on the right is just the opposite, and far rarer, where the Dashboard shows green, but the resulting cut is in chatter. In both cases the absence or presence of chatter is confirmed using Harmonizer.

You can open the Calibrate Dashboard calculator on your iPhone by using your camera and aim at the following QR code:
You can also use your iPhone's Safari browser and go to: www.taptest.co/calibrate-dashboard
If for some reason the online calculator is not available, you can use the Excel spreadsheet attached below.
HERE IS WHAT IS HAPPENING
Below are the stability lobe diagrams of the two Dashboards shown above. The customer's parameters (speed, width and depth of cut) are represented by the green dot. The upper diagram was used to create the initial Dashboard. As you can see the customer's parameters are just outside the stable lobe. We slightly adjusted the material properties. Note that the locations of the stable speeds did not change, but the height of the lobes, or maximum depth of cut, increased. In the lower diagram the customer's parameters are now in a stable lobe and show this in the calibrated Dashboard.
