The first commandment of dry machining concerns holemaking. Can a shop perform all operations dry, especially hole drilling? This is important, because it would be illogical to perform most cutting operations dry, or near-dry, then use coolant to drill holes. Of course, turning or milling operations are the easiest to convert to dry machining.
However, in other shops that also apply high speed milling—but apply it for different purposes and different materials—the picture changes. To determine whether dry machining with forced air makes sense for a given high speed milling application, consider four main process factors: Workpiece Hardness.

aluminum dry milling. i think you might be missing some important points about milling aluminum. 1) use an end mill made for aluminum. i use hi helix HSS end mill with polished flutes made for aluminum. They are a sharper rake and the polished flutes lowers friction sticking. i run aluminum at 400 - 600 SFPM.

Lubricants have always been used in mechanical processing: on the one hand in the form of cooling lubricants to dissipate heat and on the other hand oils to reduce friction and thus wear. For years there have been a few companies that sometimes dry-machine their semi-finished aluminum products. We have now made the decision for Hydro's own machining …

Dry machining is essentially machining without the use of any cutting fluid or coolant. It is becoming increasingly popular due to: Concerns regarding the environment Operator Safety – Fumes and splashing coolant Issues related to …
Yamamoto et al. (2003) has stated that the dry machining may expose machine operators to increased levels of dust, since it is assumed that use of metalworking fluids helps contain machining dust. Therefore, in machining processes, such as milling, grinding, turning, boring, and drilling, the operators usually rely on the use
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. The most common options are 2, 3, or 4 flutes. The more flutes, the more cutting edges but the
Dry machining is typically reserved for certain applications, and it may never completely replace the use of cutting fluids, but developments are being made. A significant new advancement called the ChilAire™ cooling system, offers the …
Machining. Magnesium has very good machining abilities like sawing, punching, drilling, milling, turning compared to other metals. The specific cutting power is low and the surface is excellent and the chips are short. Magnesium is the fastest machining metal and it has a high thermal conductivity. Advantages of it are for example:
Machining of aluminum and its alloy is very difficult due to the adhesion and diffusion of aluminum, thus the formation of built-up edge (BUE) on the surface. The BUE, which affects the surface integrity and tool life significantly, affects the service and performance of the workpiece. The minimization of BUE was carried out by selection of proper cutting speed, feed, depth of …

milling machine has a worktable that can swivel on the saddle with respect to the axis of the milling machine spindle, permitting workpieces to be adjusted in relation to the milling cutter. 2 The universal horizontal milling machine also differs from the plain horizontal milling machine in that it is of the ram type; i.e., the
If wet milling must be performed, sufficient cutting fluid should be used. Various similarities and differences between dry machining and wet machining are given below in table format. Similarities between dry milling and wet milling. In most cases, the processing of materials can be carried out under dry or wet conditions.
