    Abstract: Systems and method relating to machining parts include a CNC system including CNC machining tools, and a computer including a processor and a computer-readable medium, wherein the computer-readable medium encodes instructions of a single NC program that, when run on the processor, causes the computer to control a selected CNC machining tool to perform operations including alternating between (i) moving the selected CNC machining tool along a semi-finishing toolpath segment using a first set of spindle speed and feed rate values to remove a next portion of rough stock material in a next region of a part being manufactured, and (ii) moving the selected CNC machining tool along a finishing toolpath segment to remove a semi-finishing thickness portion of the part in the next region, wherein the first set of spindle speed and feed rate values are different from the second set of spindle speed and feed rate values.

    Abstract: In an end mill, a peripheral cutting edge portion has a peripheral cutting edge formed in a spiral shape around an axis, a peripheral rake face formed on the front side of the peripheral cutting edge in the rotating direction and bordering thereon and a peripheral flank formed on the rear side of the peripheral cutting edge in the rotating direction and bordering thereon. The peripheral flank has a first peripheral flank formed in a position on the mill body tip side to have a first clearance angle and a second peripheral flank formed in a position on the mill body end side of the first peripheral flank and neighboring the first peripheral flank to have a second clearance angle. An average width value of the first peripheral flank in the rotating direction is greater than an average width value of the second peripheral flank in the rotating direction.

    Abstract: A blade of an impeller has a blade surface made up of line elements. The line elements forming the blade surface are not parallel to each other. A relationship between a twist angle of the line elements and a distance between the origin and an intersection of a central line of the impeller and an extension line of a Z-axis projection line obtained by projecting each of the line elements onto a Z-axis projection plane is represented by a curve.

    Abstract: Machine tool systems and methods include methods of synchronizing cutting tools with a workpiece retainer. In some embodiments, the methods and systems provide at least two cutting tools that are synchronized to machine a common surface of a workpiece in a quick and efficient manner. A controller having a single line of code for controlling both cutting tools and the workpiece retainer may be used. The cutting tools may be synchronized such that they engage substantially opposite portions of the workpiece, thereby to reduce resulting forces in the workpiece that may tend to induce workpiece deflection and/or chatter. In other embodiments, a cutting tool is synchronized with a split workpiece holder that may be controlled to induce a compression, tension, or torsion pre-load in the workpiece.

    Abstract: A plunge milling method includes: a) the area of material that is to be removed is enclosed by a plurality of milling paths, each milling path defining end positions of a milling head during the formation of plunge milling bores; b) to each milling path there is allocated a guide curve for the tool axis, each guide curve defining initial positions of the milling head during the formation of plunge milling bores; c) during the formation of plunge milling bores, the tool axis is oriented, as a function of a milling path and the respective guide curve, so that there is no danger of collision of the milling tool with a contour formed by plunge milling; d) for each milling path, bore axes for plunge milling bores are determined as a function of the respective guide curve, corresponding to a prespecified overlap of milling bores formed along the milling paths.
