摘要： To provide a machine tool that is capable of limiting degradation of machining efficiency when a cutting tool machines a workpiece by performing one repetitive movement with respect to multiple relative rotations between the workpiece and the cutting tool, and a control apparatus of the machine tool. In the machine tool (100) and the control apparatus (C) thereof, the repetitive movement means is configured so that the cutting tool (130) performs one repetitive movement with respect to multiple relative rotations between the workpiece (W) and the cutting tool (130) and so that a rotation angle of the relative rotation between the workpiece (W) and the cutting tool (130) during relative movement at the second speed is smaller than a rotation angle of the relative rotation during relative movement at the first speed in one repetitive movement, thereby limiting degradation of machining efficiency when the cutting tool (130) machines the workpiece (W) by performing one repetitive movement with respect to multiple relative rotations between the workpiece (W) and the cutting tool (130).

摘要： To provide a machine tool that is capable of preventing a long, continuous chip from getting entangled with a workpiece or a cutting tool when a threading work is performed on the workpiece, and a control device of the machine tool. A machine tool (100) is capable of performing a threading work by relatively feeding a workpiece (W) and a cutting tool (130) in a feeding direction while relatively rotating the workpiece (W) and the cutting tool (130) and by performing a cutting work for multiple times in a helical manner while reciprocally vibrating the workpiece (W) and the cutting tool (130) in a relative manner in a radial direction of the workpiece (W), and the machine tool (100) or a control device (C) of the machine tool (100) includes vibration setting means (C1) to set a pattern of vibration during each cutting work accompanied by the reciprocal vibration so that a cut portion of one cutting work partially includes a portion that has been cut in another cutting work.

摘要： A weld bead chopper (10) is provided, for use in combination with a scarfing tool (13) which is intended to scarf a longitudinal weld bead (30) from a tube (12). The chopper (10) has a) a chopper blade (15) which is rotatable about an axis which is substantially perpendicular to a longitudinal axis of the tube (12), and b) a stationary blade (16) which is cooperable with the rotatable blade (15). The cooperating chopping surfaces of the rotatable and stationary blades (15, 16) are at a short distance from the weld bead (30), e.g. less than 100 mm, and preferably from 20 to 50 mm. The scarfed weld bead (25) enters an enclosed throat (19) which has walls (36, 37, 38) to guide a scarfed weld bead (25) towards the cooperating chopping surfaces. The throat (19) has a first guide (35) adjacent to the scarfing tool (13) which directs the scarfed weld bead (25) towards a second guide (20). The second guide (20) faces the scarfing tool (13), and is adapted to guide the scarfed weld bead (25) towards the cooperating chopping surfaces. The throat (19) has a cross-sectional area substantially larger than the cross-sectional area of the scarfed weld bead (25). Additionally, the throat (19) has a mouth (33) which is sufficiently small to prevent the scarfed weld bead (25) from exiting from the mouth (33).
摘要翻译：提供焊缝切碎器（10），用于与打算从管（12）围绕纵向焊缝（30）的清理工具（13）组合使用。切碎机（10）具有：a）可绕着基本上垂直于管（12）的纵向轴线的轴线旋转的切碎机刀片（15）;以及b）固定刀片（16），其可与可旋转刀片（15）。可旋转和固定刀片（15,16）的协作切割表面与焊缝（30）的距离很短，例如，小于100毫米，优选20至50毫米。有棱角的焊缝（25）进入封闭的喉部（19），该喉部具有壁（36,37,38）以朝着相配合的切割表面引导清理的焊缝（25）。喉部（19）具有与清理工具（13）相邻的第一导向件（35），该清理工具（13）将清理后的焊缝（25）引向第二导向件（20）。第二引导件（20）面向清理工具（13），并且适于朝着协作的切碎表面引导清理的焊缝（25）。喉部（19）的横截面面积明显大于被划线的焊缝（25）的横截面面积。另外，喉部19具有足够小的嘴部33，以防止被划痕的焊缝25从嘴部33中流出。

摘要： A tool assembly having a tool block (50) and a tool holder (12). The tool block has a fluid passage (92) having an outlet (93). A fluid passage (104) in the tool holder shank (14) has an inlet (102) including a shallow recess (99) configured to maintain fluid communication through a range of relative movement of the block and holder. The fluid passage terminates in a discharge orifice (114) to direct a fluid jet at the chip being removed from the workpiece.
