Abstract: The present invention relates to a method and apparatus for measuring cutting forces associated with a machine tool (10). A force transducer plate (28) forms a part of a bolted joint within the machine tool structure and is positioned within a direct force path. Raised force shunting pads (38) are formed on both sides of the plate thereby limiting the load transfer area of the plate. At least one three-axis load cell (46) is mounted closely adjacent one force shunting pad and elevated relative to the pad such that an acceptable preload is maintained on the load cell. By strategically placing the load cell closely adjacent the force shunting pad and utilizing the force shunting pads to transfer the majority of loads through the plate, hysteresis is minimized, linearity optimized, and the load cell protected from overload.

Abstract: The present invention entails a tool holder (10) adapted to be inserted within the tool slot (14) of a lathe turret. The tool holder includes a detachable cutting unit (20) and a clamping unit (18). Forming a part of the clamping unit is a pair of wedge blocks (80) disposed within wedge cavities formed within the clamping unit. The wedge blocks are movable via screws (92) from an inner relaxed or disengaged position to an outer position where the wedge blocks engage the tool slot and through a wedging action function to secure the tool holder within the tool slot of the lathe turret.

Abstract: An angle spindle attachment for a vertically movable spindle unit (29) is provided for rotating a cutting tool (4) in a generally horizontal orientation. The attachment includes a spindle assembly (43) having a drive train (44) that is mechanically independent from the drive train of the vertically movable spindle unit, and a connector block for detachably connecting the spindle assembly at a transverse angle with respect to the vertically movable spindle unit. The connector block (105) may include an angular adjustment mechanism (107) that allows the spindle assembly to be oriented at an angle above or below the horizontal, as well as a rotational adjustment assembly that allows the spindle assembly (43) to be pivotally adjusted about the axis of rotation of the vertically movable spindle unit. The independent drive train of the spindle assembly may be either electrically, hydraulically, or pneumatically powered, and allows the cutting tool to be held more rigidly, operated with less eccentric movement, and turned at speeds that are not limited by the drive train of the vertically movable spindle unit.

Abstract: A cutting insert (10) for grooving operations with chip control features having an insert body (12) with peripheral walls, sides and first and second end walls to define cutting edges (26, 28) within cutting edge regions and adapted for mounting in a pocket (74) of a toolholder assembly (70). A land extends (34) rearwardly from the end wall and defines a width. A descending wall (50) initiates in the land and terminates in a floor (58) having a forward (52), a rearward (60) and opposed side edges (54, 56). A back ramp (60) extends upwardly from the floor rearward edge and terminates at the respective peripheral wall (22) to define a cavity. A pair of projections (62, 64) extend longitudinally along the sides of the cavity to promote chip control and intersect with diagonal side ramps (66, 68) rearward of the cavity. The side ramps (66, 68) may be used to provide a chamfer on the edges to the machined groove.

Abstract: An insert for use in a ball nose end mill (1) is provided that includes an insert body (22) having a top wall (24), a bottom wall (28) and at least one arcuate side wall (30). An arcuate cutting edge (34) is defined at an intersection between the top and side walls that includes a plurality of sinusoidal undulations (36) for reducing cutting forces, and vibration, and enhancing the breaking and removal of chips removed from a workpiece (66) during a cutting operation. An end portion (67) of the insert crosses the axis of rotation (A) when the insert is mounted in the seat of an end mill body (3), and the undulations (36) reduce the considerable shear forces applied to the cutting edge (34) at this location. The cutting edge has a profile which follows the contour of a sphere to permit machining a rounded cut. The side wall (30) of the insert body includes an upper relief portion (44) disposed directly under the cutting edge, with a relief angle for preventing the undulations from making unwanted striations or tool marks in the sidewalls of the rounded cut.
