A cooling block includes a body having a thermal transfer surface configured to be in thermal contact with a heat-generating electronic component. The body defines a fluid conduit having a plurality of channels such that the cooling fluid flows in parallel along the channels. Each channel is defined between first and second internal sidewalls; and top and bottom walls. Each channel has either: a first dimensional configuration including first height and width values; or a second dimensional configuration including second height and width values. The first height value is greater than the second height value. The second width value is greater than the first width value. A thickness of a material of the body between the thermal transfer surface and a first channel is less than a thickness of the material of the body between the thermal transfer surface and a second channel.

This tool path generating method, which generates a tool path for machining a corner section at which a recess section machined in a workpiece intersects with the outer circumferential surface of the workpiece, includes: a step for calculating a virtual traveling direction, which is a movement direction of a point on the rotational axis line of a rotating tool when the recess section is machined; a step for calculating the position of the corner section from the virtual traveling direction and shape data of the workpiece; and a step for generating a tool path for machining along the calculated position of the corner section.

An improved method of machines grooves forming Pearson notches in a pattern on hollow shell casings for munitions for at least one of increased functionality and/or performance. Rather than running a broach through a hollow casing, a CNC lathe with a multi-axis tool with cutting implement can precisely locate and form grooves along either an interior or an exterior surface of a hollow shell casing.

Methods and devices for milling a channel-shaped cavity by a five-axis computer numerical control (CNC) machine by selecting a workpiece to be machined, determining cutting tool flow along the channel-shaped cavity, determining cutting tool in-depth penetration, determining a trochoid path, and determining auxiliary movements.

In a method for producing a cavity (14) in a stator of an eccentric screw pump, material is removed in the interior of a stator blank (10) by means of a tool (11). In order that very long stators can be produced in one production operation, the tool (11) performs a rotational motion through a first shaft (12) and an eccentric motion around a second shaft (13), during which the stator blank (10) and the tool (11) are moved toward each other. A device for performing the method comprises (a) a bearing shaft (3) that can be coupled with its drive end to a first drive and that is rotatable around its longitudinal axis by means of the first drive; (b) a drive shaft (4) that can be coupled with its drive end to a second drive and is arranged in a borehole of the bearing shaft (3) and is rotatable around its longitudinal axis by means of the second drive form-fitting and relative to the bearing shaft (3), and (c) a machining tool (5), which is rotationally fixed connected to the machining end of the drive shaft (4) that can be inserted into the cavity and can be driven rotatably via the drive shaft (4) around the longitudinal axis of the drive shaft (4). The longitudinal axis of the drive shaft (4) intersects the longitudinal axis of the bearing shaft (3) at a point or is arranged askew to the longitudinal axis of the bearing shaft (3).

A tool (T) is provided with: a shaft-like tool body (11) having a first end portion (11a) extending along a central axis line (Ot) and attached to a main shaft, and a second end portion (11b) on an opposite side to the first end portion (11a); and a fore end portion (12) connected to the second end portion (11b) of the shaft-like tool body (11). The fore-end portion (12) includes a central portion (13) including a fore-end face (17) of the tool (T), and a plurality of blade portions (14) protruding radially outward from the central portion (13). A cutting blade of each blade portion (14) includes a main cutting blade (15) adjacent to the fore-end face (17). The main cutting blade (15) includes an outline that forms an angle of 30-150 degrees with respect to the central axis line (Ot) in a cross-sectional view including the central axis line (Ot).
