1.Detecting CNC Tool Failures with Accelerometer Data
scatter plot and bar chart · 2026
A manufacturing process engineer needed to detect CNC tool failure signatures to shift from reactive scrap analysis to proactive signal monitoring. The dashboard analyzes accelerometer data, using a scatter plot to correlate maximum amplitude with Y-axis kurtosis. Nominal operations cluster at a high kurtosis of 7.0 with amplitudes above 2000, while anomalous cycles drop to negative kurtosis values (-0.72 to -0.03) and amplitudes below 1000. A cycle length bar chart confirms that bad cycles prematurely shorten from 60,000 to roughly 40,000 data points. This statistical visibility allows the engineer to identify tool disengagement before ruining precision parts.
What it shows:
Correlating Y-axis kurtosis and amplitude identifies CNC tool disengagement before parts are scrapped.
