Mar 01, 2000 High-speed milling of hardened die steels was second choice at 49 percent. Since then, it has gained more acceptance in the industry. 1 The following observations from the Engineering Research Center for Net Shape Manufacturing (ERC/ NSM) at The Ohio State University may be useful to shops contemplating getting into high-speed milling.

Requirements for milling hardened steels

Dec 01, 2011 In general, hard milling involves cutting primarily tool steel or precipitation hardening stainless steel, such as 15-5 or 17-4, that has been hardened to at least 50 HRC. After a workpiece is roughed in the soft state, it is sent to the furnace for hardening and then finish machined with coated carbide, ceramic or PCBN tools.

Roughing is normally carried out in the non-hardened condition and can be compared with milling of a high alloyed steel. The finishing operation, however, is performed in the hardened material, which is very abrasive. This can be compared with milling of hardened steels, ISO H. Grades with high resistance against abrasive wear are preferred.

– Climb mill with this 2/3’s cut ratio. Conventional milling with a face mill causes the chip to start out thin, which sometimes leads to rubbing at the outset of chip formation that is bad for surface finish and can lead to BUE. The best finishes start the chip out fat and then thin it out before the chip releases.

Apr 20, 2011 While carbide is hard enough to cut hardened steel, it must be forced to cut. This means a positive feed and decent chipload is required with every chip. But the stiffness of carbide, while better than HSS, is not infinitely stiff, and taking a deep cut in hard steel simply requires more tool pressure than the tool shank can deliver.
