In one aspect, an additive-manufacturing system includes an additive-manufacturing head and a surface-processing device coupled to the additive-manufacturing head. In another aspect, a surface-processing apparatus for an additive-manufacturing head includes a housing configured to be coupled to the additive-manufacturing head and a surface-processing device coupled to the housing. In a further aspect, a method of forming a product using an additive-manufacturing head includes forming one or more layers of the product with the additive-manufacturing head and processing at least one of the one or more layers of the product with a surface-processing device coupled to the additive-manufacturing head.

A method for producing a replaceable cutting head is described. The replaceable cutting head is manufactured by extruding a blank. During extrusion of the blank, a number of helical coolant channels and a number of helical flutes are simultaneously formed. After extrusion, the flutes have a first angle of twist (D1), and the coolant channels have a second angle of twist (D2). After extrusion, the blank is sintered and then reworked to selectively adjust the first angle of twist (D1) and the pitch of the flutes. The method produces an endless blank that is capable of being parted off to a desired length without any sacrificial allowance, which provides significant material and cost savings as compared to conventional methods.
