摘要:
Disclosed are a method and apparatus in the field of computer numerically controlled machine tools. A rotating workpiece is brought into contact with a tool, the tool being disposed in a rotating tool holder and traversing an eccentric path. By rotating the tool holder and workpiece synchronously, various characteristics forms may be produced. The method in some embodiments is useful in the turning of noncircular shapes, such as ovoid pistons and other parts.

Disclosed are a tool indexer assembly, a computer numerically controlled machine that includes such tool indexer assembly, and associated methods. The assembly in one embodiment includes a turret and an indexer, the indexer including a portion that is movable with respect to the turret and that includes plural tool station configured to receive plural tool structures. The tool indexer is disposed on a facet of the turret, and, in some embodiments includes a table that is rotatable about an axis that is generally orthogonal to the axis of rotation of the turret. In another embodiment, a tool indexer includes a clamping mechanism having a source of pressurized fluid and a piston that is hydraulically actuated by the pressurized fluid and movable to a clamping position. The assembly further includes a conduit for delivery of the pressurized fluid proximal the tool structure as coolant fluid.

Disclosed in one embodiment is a computer numerically controlled machine having a coolant nozzle that is mounted on a turret of the machine and that is rotatable relative to the turret under the control of a computer control system. The nozzle is fluidically connected to a source of a coolant. The machine includes a computer control system that is operatively coupled to the various components of the machine including the nozzle. In some embodiments, the nozzle may be moved to cause a constant contact angle with respect to one of said tool and said workpiece. In other embodiments, the nozzle may be moved to cause a constant coolant time to interface. Also disclosed are related methods.

Disclosed are a machine with a grinding wheel and a dressing surface and related method. The dressing surface is movable in at least two axes of translation relative to the grinding wheel. The rotational speed of the grinding wheel and dressing surface preferably are under the control of a computer control system, whereby the speed of rotation of the dressing surface may be adjusted as the diameter of the dressing wheel and as the diameter of the grinding wheel is decreased during use. The machine may be used in continuous or intermittent dressing operations.

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.
