This study aims to investigate the effects of dry, minimum quantity lubrication (MQL), and nanofluid cutting conditions on surface roughness (Ra) and material removal rate (MRR) for Al6082T6. Three controllable factors, namely, feed rate (Fr), spindle speed (Vs), and depth of cut (Dc) are studied at three levels using Taguchi method. Singleresponse optimization is conducted using S/N ratio ...

newer milling machines or machines with minimal spindle wear. Rigidity is critical when using carbide tools. Carbide end mills may require a premium price over the cobalt end mills, but they can also be run at speeds 2 1/2 times faster than HSS end mills. The choice of tool material depends on the material to be cut as well as on the maximum

Face milling operation is performed on vertical milling machine (HURCOVM10) with the help of carbide insert shown in Fig. 1. The cutter of diameter 80 mm with equally spaced seven numbers of cutting inserts is used for face milling. Initial and final weight of specimen is required to calculate the MRR along with machining time.

The Axia depth of cut is also called Stepdown and Cut depth. It is designated by ap or ADOC. The maximum possible depth depends mainly on the cutter's diameter. For large diameter cutters (Above 3/4″, 20 mm), It is up to 4D (4 times the diameter). For small diameter cutters (Below 1/8″, 3 mm) it is up to 10D.

Two NC sequences are used for the rough cut, a face milling that removes the layer of in. material on the top face, and then a pocket milling that cuts the center pocket. A 1 in. diameter cutter of 4 teeth is employed for both sequences. A ¼ in. cutter of length in. with 4 teeth is then used for finish cutting.
