  • Patent number: 8234958
    Abstract: A toolholder with a controllable critical angle, such as a lead, trailing, rake or clearance angles, includes a tool spindle for retaining the toolholder in a tool rest of a machine tool. The machine tool includes at least one linear axis, for example, three mutually perpendicular axes, a rotary axis and a rotation axis. The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor supports a cutting tool that is retained in the adaptor by a clamp. The cutting tool defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder is also disclosed.

  • Publication number: 20120152069
    Abstract: Computer numerically controlled (CNC) machines, adjustable material-working tools, and methods of operating an adjustable tool with a CNC machine are presented herein. An adjustable tool for a material-working machine is disclosed. The adjustable tool includes an elongated housing, and one or more cutting inserts at least partially disposed within the housing. Each cutting insert is selectively transversely repositionable with respect to the housing. A wedge is selectively longitudinally repositionable with respect to the housing. The wedge mates with the cutting insert(s) such that longitudinal movement of the wedge effectuates transverse movement of the cutting insert(s). A control arm is movably mounted to the housing. The control arm is configured to mechanically couple the wedge to a prime mover of the material-working machine such that motive force is transferred from the prime mover through the control arm to the wedge for the selective repositioning thereof.

  • Publication number: 20120096999
    Abstract: A method of machining a workpiece may include continuously rotating the workpiece, continuously rotating a tool having at least one cutting surface, and positioning the tool relative to the workpiece so that the at least one cutting surface engages the workpiece at a first discrete location at a periphery of the workpiece. The method may further include continuing to rotate the workpiece and the tool so that the at least one cutting surface engages a second discrete location at the periphery of the workpiece, and controlling a tool surface velocity VT relative to the workpiece surface velocity VW so that the first and second discrete locations are discontinuous. The tool may make multiple iterative passes over the workpiece to engage subsequent discrete locations, wherein the first discrete location, second discrete location, and multiple subsequent discrete locations may form a machined surface that extends continuously around the workpiece.

  • Publication number: 20110209529
    Abstract: An apparatus for obtaining information about a workpiece may include a measuring device having a nozzle defining an orifice in fluid communication with a source of incompressible fluid. A fluid monitoring apparatus may monitor a parameter of the substantially incompressible fluid, and a pump may be fluidly coupled to the source and configured to supply incompressible fluid to the orifice. The pump may have a pump chamber with a first displacement setting having a first fixed volume, so that operation of the pump at a first pump speed with the pump chamber in the first displacement setting generates a first fluid flow having a substantially constant first volumetric rate. The pump may have more than one displacement setting, or the pump may be operated at different speeds to change the volumetric flow rate. The nozzle may include multiple, independent orifice sets that may be selectively provided fluid, thereby to obtain information on different parts of the workpiece with a single placement of the nozzle.

  • Publication number: 20100278606
    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.
