The milling process is interrupted cutting, and the chip control features of milling tools are usually not as important as in turning. According to the material of the workpiece and the arc of engagement involved, it may become very important to determine the energy required to form and guide the chip. Narrow or forced chip-breaking chip control geometries can immediately roll up the chips and generate greater cutting force and more heat. More open chip control geometry can produce smaller cutting force and lower processing temperature, but may not be suitable for certain workpiece material and cutting parameter combinations.
A variety of related factors together form the load in metal cutting. In the process of processing, these factors will affect each other. This article discusses the thermal issues in milling and their relationship with mechanical factors. Familiarity with the factors that generate metal cutting loads and the overall results of their interactions will help manufacturers optimize their machining processes and maximize productivity and profitability.
