    摘要： The invention relates to a method for cutting teeth into working gears (1) using a tool (2), the tool main part (11) of which has a plurality of cutting teeth (3) which are arranged about a rotational axis (5) and which protrude radially from the tool main part (11), said cutting teeth (3) forming an end face (7), two tooth flanks (6, 6') which point away from each other, and cutting edges (18, 19). The cutting edges (18, 19) are formed from the tooth flank (6, 6') edges adjoining the end face (7). In a first method step, tooth gaps (17) which form tooth flanks (14, 14') are produced in the working gear (1) by means of the cutting edges (18, 19) using a machining process in a first position of the tool (2) relative to the working gear (1), and in a second method step, the working gear (1) tooth flanks (14, 14') produced by the cutting edges (18, 19) are fine-machined by an abrasive tool surface. The aim of the invention is to develop the known machining method so as to be advantageous for use and to provide a tool and a device which are suitable for the method. According to the invention, this is achieved in that the abrasive tool surfaces are made of the tooth flanks (6, 6') of the tool (2), which operates in a second position that differs from the first position relative to the working gear (1) in the second method step.

    摘要： A rotating cutting tool to cut asymmetrical teeth in a gearwheel in which each tooth (21) has an active flank (A) with a convex profile meshing with the profile of a tooth of an opposing gearwheel meshing with the gearwheel and a secondary concave flank (S), provided with teeth (11) on a generally helical path which extends from one side to the other with respect to a median cross-section (M-M) of the tool which is intended to be intersected by the radius Rp of the gearwheel which is at right angles to the axis of rotation of the tool working on the gearwheel to cut its teeth. The helical teeth have a first flank (CA) which is intended to cut the said active flank (A) of the gearwheel teeth and a second flank (CS) intended to cut the secondary flank (S), the pitch (P1) between the first flank (CA) of the helical teeth being constant and the pitch (P2) of the second flank of the teeth being smaller than the pitch (P1).

    摘要： The disclosed system includes a personal computer (10) having correction coefficients (±) for the correction of errors in the tooth profile and correction coefficients (²) for the correction of meshing positions, the correction coefficients being provided for each number of times the shaving cutter has been sharpened and for each shaving-cutter feature. The target tooth-profile data (Do), the tooth-profile error data (”D) which is the difference between the target tooth-profile data (Do) and the measured tooth-profile data (Dm), and the correction coefficients (± and ²) acquired in correspondence with the number of times sharpened and the cutter features are applied to the equation Dcc=Do+±”D+², to fnd the aimed tooth-profile data (Dcc). Then, the shaving-cutter tooth-profile data (ds) is found from the aimed tooth-profile data (Dcc). Thus, the shaving cutter can be sharpened appropriately, even when the outer diameter and the tooth thickness of the shaving cutter are reduced as a result of sharpening the shaving cutter.

    摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-Al 2 O 3 layer. The α-Al 2 O 3 layer contains a plurality of α-Al 2 O 3 crystal grains and chlorine, and has a TC(006) of more than 5 in texture coefficient TC(hkl). The α-Al 2 O 3 layer includes lower and upper layers, the lower layer is located closer to the base material than the upper layer is, and the upper layer is located opposite to the base material across the lower layer, in a thickness direction of the α-Al 2 O 3 layer. The lower layer has a thickness of 1.0 µm. The upper layer has a thickness of 0.5 µm or more. The chlorine in the lower layer has a concentration distribution in which an atomic concentration C Cl of the chlorine decreases in a direction away from the base material, in a thickness direction of the lower layer.
