A slot milling sequence includes a plurality of material removal processes or operations. Each of the material removal operations includes utilization of an end mill tool. Some of the material removal operations utilize trochoidal tool paths, whereas other material removal processes utilize one or more profile cuts. Some material removal operations that utilize profile cuts remove material from both sides of the cut in a single pass, whereas other material removal operations remove material from one side of the cut via a first pass of the end mill tool and remove material from the opposing side of the cut via a second pass of the end mill tool.

The present disclosure provides steel backing plate wiredrawing equipment and method. The equipment includes a support frame; a first longitudinal rail and a second longitudinal rail which are respectively arranged on two sides of the support frame and are parallel to each other; a longitudinal movement frame slidably arranged on the first longitudinal rail and the second longitudinal rail; and a transverse movement frame slidably arranged on the longitudinal movement frame. A numerical control cutting machine, a vacuum cylinder, a glue dispenser, and a spot welder are integrated on the transverse movement frame; the longitudinal movement frame is provided with a power mechanism I, and the transverse movement frame is provided with a power mechanism II; the support frame is provided with a support plate; and the support plate is provided with a first laminate and a second laminate which are made of steel in sequence from bottom to top.

This grooving tool includes a cutting insert, a holder, and a coolant flow path. The holder includes an insert mounting seat, and jaw parts that are disposed on an upper side and a lower side of the insert mounting seat and fix the cutting insert. The jaw part forms a curved shape as viewed from a tool distal end side, and has a thickness that is decreased as a distance from the insert mounting seat is increased. The coolant flow path includes a jaw part flow path extending through an inside of the jaw part, and the jaw part flow path includes a guide flow path section that has a vertically elongated shape with a dimension a in the vertical direction larger than a dimension b in the tool width direction in a channel cross section, and an ejection flow path section that has a laterally elongated shape
