This work presents an analytical cutting force modeling for micro-slot grinding. Contribution of the work lies in the consideration of both primary and secondary tool surface interactions with the work surface as compared to the previous works where only primary tool surface interaction was considered during cutting force modeling.
Florida, Louisiana and Hawaii) have used mechanical harvesters for several years. After cutting, the cane is loaded by hand, mechanical grab loaders, or continuous loaders. Cane is transported to the mills using trailers, trucks, railcars, or barges, depending upon the relative location of the cane fields and the processing plants.

The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
or specialization, should know. Note that this book is not a book on 'Workshop' Technology'. 'Workshop Technology' is usually taught as 'Workshop-Practice' usually with 0-1-3. L-T-P, meaning by 3-lab hours and 1 hour for tutorial (or lecture) for …
The problems, such as low automation, harsh environment, labor intensity of manual work, poor stability of processing quality, and inefficiency, however, generally exist. Therefore, efficient and intelligent grinding equipment and technology for large-scale complex structural components is an urgent problem to be overcome.
Grinding burn is caused by excessive heat produced during grinding process. It changes the surface hardness and reduces the fatigue resistance which brings great damage to work-piece [1, 2].Grinding burn is widespread in the field of cylindrical grinding, rail grinding, bearing rings grinding, and so on [3,4,5].Therefore, the detection and monitoring of grinding …
