How to Analyze Gear Failures
When an important gear failure occurs, someone becomes responsible for analyzing the failure, determining its cause and recommending a solution. A company can select its own engineer, an outside consultant or both. If a consultant is called in, this should be done as early in the process as possible. Though similar procedures apply to any failure analysis, the specific approach can vary depending

Introduction to Milling Tools and Their Application
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.

Ball mill
A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Cadia Girth Gear Failures
The gears and pinions on the Cadia ball mill gears failed due to a design fault. We agree with [2] that a larger pinion may have avoided the gear scoring, however, the location of the damage can only be explained by thermal ratcheting resulting in differential expansion. The damage to both the loaded and unloaded flanks of the girth gear are consistent with the gears almost jamming.
