What This Means for Your Design

When you use a tool to make many small holes, the tool wears down, especially on the sides. This makes the holes not perfectly straight. By measuring how much the tool wears on the sides, you can adjust how deep you machine to make the holes straight again, improving their quality significantly.

Paragraph starter

The challenge of maintaining dimensional accuracy in micro-manufacturing due to tool wear is significant. Research by Azhar and Saleh (2025) demonstrated that in hybrid LBMM-µEDM processes, radial tool wear can lead to undesirable hole tapering. Their proposed compensation strategy, involving programmed depth adjustments based on measured radial wear, successfully reduced taper angles by a factor of seven, enhancing hole quality and process consistency.
