A structural profile includes an outer contour that has at least one longitudinal side and one transverse side. The longitudinal side and the transverse side are transverse to one another. The longitudinal side has a longitudinal-side groove and the transverse side has a transverse-side groove. The grooves each have a respective groove cross section in which a circle is capable of being inscribed. Longitudinal center axes of the grooves are arranged in a common groove plane, and the groove plane is parallel to a longitudinal center plane of the structural profile.

A tooling base assembly for holding a workpiece is disclosed. In one example, the tooling base assembly includes a base assembly and a clamping assembly that imparts an inward radial force towards a center of the base assembly on the workpiece to securely retain and precisely locate the workpiece to the base assembly.

The present invention relates to a slanting-bed feed processing machine tool of a large propeller. The machine tool comprises a slanting column feed bed, a machine tool spindle, a workpiece rotary worktable, a large propeller and a bed feed mechanism. The present invention coordinates the geometrical relationship between the machine tool and the large propeller to ensure that the slanting column feed bed moves between two blades, thereby reducing the overhang length of the spindle. Different forms of workpiece rotary worktables and bed feed mechanisms are selected according to different slanting column feed beds. Four types of slanting column feed beds are designed, which can be selected, optimized and applied for different processing objects. The present invention enhances the processing stiffness of the spindle and solves the problem of poor processing quality of the large propeller caused by machine tool vibration.

A positioning unit includes two control carriages and a work carriage, it being possible to move the two control carriages and the work carriage on tracks that extend in parallel with one another. There is a working arm being articulated on a work base point on the work carriage and a control arm being articulated on a control base point on each of the control carriages. The control arms are articulated on the working arm at a control point of the working arm, the control point being spaced apart at a predefined lambda distance (d) from an end of the working arm that forms a working-point end and faces away from the work base point, and the two control base points and the work base point defining a triangle. At least two carriages of the two control carriages and the work carriage are movably arranged on a shared guide.

A vibration assisted drilling system is presented. The vibration assisted drilling system comprises a drill feed motion system having a drill feed axis, an oscillation motion system having an oscillation axis, a drill spindle having a drill bit, and a mounting system configured to connect the drill spindle to the oscillation motion system. The drill feed axis is substantially parallel to and offset from the oscillation axis.

A machine for producing two or more drill holes in a surface of a panel. The machine includes a feeding device for feeding the panel in a feeding direction and a drilling device including two or more drilling units. The drilling units are displaceable relative the surface in a drilling direction which is at an acute angle relative the surface of the panel.

A structural profile includes an outer contour that has at least one longitudinal side and one transverse side. The longitudinal side and the transverse side are transverse to one another. The longitudinal side has a longitudinal-side groove and the transverse side has a transverse-side groove. The grooves each have a respective groove cross section in which a circle is capable of being inscribed. Longitudinal center axes of the grooves are arranged in a common groove plane, and the groove plane is parallel to a longitudinal center plane of the structural profile.
