[1] Wear and tear is a form of depreciation, which is assumed to occur even when an item is used competently and with care and proper maintenance. [2]
Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10-1 have been observed, the ...
In 1989, Calhoun was the first residential college to be renovated. The renovations, mostly funded by alumnus Roger Horchow, were done quickly and over the summer to minimize disruption to student life, and by 2000, the physical plant began to show wear and tear again.

Types of wear include: flank wear in which the portion of the tool in contact with the finished part erodes. Can be described using the Tool Life Expectancy ...
