A machine tool includes a main spindle that rotates while holding a workpiece, a mover that moves a cutting tool including a linear cutting blade that cuts the workpiece, with respect to the workpiece in a moving direction including at least a Z-direction parallel or substantially parallel with the axis of the main spindle and a Y-direction perpendicular or substantially perpendicular to both the Z-direction and an X-direction determining the amount of cutting of the workpiece, a holder that holds the cutting tool in a state in which the direction of the linear cutting blade is inclined with respect to the Z-direction by a predetermined angle when seen from the X-direction, and an angle adjuster that changes the edge angle.

A feeding device includes a sliding member, a main shaft, a tool holding assembly, a locking assembly, and a locking assembly. The sliding member is slidably couplable to a moving member. The main shaft is rotatably coupled with the sliding member. The tool holding assembly includes a connecting member detachably connectable to the main shaft and configured for holding one of a plurality of tool heads, the connecting member defining two clamping grooves. The locking assembly is positioned on the sliding member having a driving member attached to the sliding member, and a pair of claws attached to the driving member. The disclosure also supplies a machine tool using the feeding device, and a method for machining using the machine tool.

A machine tool having a monolithic base is disclosed. The monolithic base includes at least two flat surfaces that are mutually orthogonal and that are convex with respect to each other. The machine tool includes at least two moveable stages, each mounted to one of the flat surfaces, and each stage also being mutually orthogonal.

A method of manufacturing a component includes shaping a workpiece into a component having a desired shape and drilling a plurality of holes in said workpiece. The drilling includes continuously moving said workpiece and selectively operating a laser when said workpiece is at a predetermined position. The shaping and drilling occur in the same piece of equipment.

A tooling assembly for a lathe machine includes a tool platform configured to be mounted on the lathe machine, a milling tool holder fixedly secured to the tool platform and workable to releasably secure a thread milling tool therein, and a milling tool drive. The milling tool drive is operatively connected to the milling tool holder and operable to rotate the milling tool holder independently of a work holder to mill threads on the workpiece when a pipe thread milling tool is secured in the milling tool holder. Computer numerical control threading lathes and methods of milling threads in tubular workpieces are also described.
