    摘要： An improved centrifugally-cast tube is provided, along with a related method and apparatus of making the tube. The tube includes a plurality of grooves and bosses that are mechanically machined into an interior surface of the tube, such as by a broaching process. The profile of grooves and bosses may be defined by a plurality of intersecting concave and convex radii. The tube is resistant to creep, carburization and metal dusting. The tube also has an enhanced heat transfer rate, and a desirable surface roughness. A method of making the tube is also provided. The method essentially consists of mechanically deforming the interior surface of the tube by passing a series of cutting inserts on support rings having incrementally-differing dimensions over the interior surface. An apparatus is also provided which includes a telescoping shaft upon which is mounted at least one cutting tool that has a plurality of cutting inserts and is adapted to form a plurality of grooves and bosses in the interior surface of the tube. The grooves and bosses may be straight or spiraled.

    摘要： A system and method for cutting a profile along a linear edge of a wooden workpiece utilizes two spaced-apart rotatable cutting tools whose cutting edges mirror one another and which are mounted for rotation about parallel axes. The cutting tools are rotated in opposite rotational directions, and a support surface supports the workpiece for movement along each of the two cutting tools. By positioning the workpiece upon the support surface so that the linear edge thereof extends between the two cutting tools, the workpiece can be moved in one direction into cutting engagement with a first of the rotating cutting tools and subsequently in the opposite direction into cutting engagement with the second of the rotating cutting tools. By halting and subsequently reversing the movement of the workpiece along the first cutting tool before the cutting edges thereof exit a trailing (side) edge of the workpiece, the likelihood that the workpiece will be damaged from the profile-forming process is reduced.
