A processing apparatus includes: an apparatus main body including a base portion that is movable and a liquid supply unit that supplies a liquid to the base portion; a chuck portion connected to the base portion and including an attachment hole that is open outward; and a processing tool detachably mounted on the chuck portion. The processing tool includes a cylinder fitted into and held by the attachment hole, a drive unit disposed inside the cylinder and including a rotating body to be rotated around a central axis by the liquid introduced from the liquid supply unit via the base portion, a rotary shaft protruding outward from an inside of the cylinder along the central axis to rotate integrally with the rotating body, and a tool portion connected to a tip of the rotary shaft.

An assembly, an apparatus, and a method for machining a mechanical part. The assembly includes a parallel robot adapted to be mounted onto a platform under the mechanical part to be machined. The assembly includes a servo spindle mounted on the parallel robot and configured to drive a machining tool to rotate. The parallel robot is configured to drive the servo spindle to translate along the one or more axes with respect to the parallel robot. During the machining of the mechanical part, the parallel robot may drive the servo spindle to translate along the one or more axes under the mechanical part, such that the machining tool may cut out the required shapes and characteristics at a bottom side of the mechanical part.

A position measuring device includes a scale carrier with a measuring scale. A scanner is configured to generate position signals by scanning the measuring scale. A processor is configured to process the position signals into a digital position value. An interface is configured to communicate with downstream electronics. At least one collision sensor is assigned to the position measuring device, and is configured to generate analog or digital measured values from a time characteristic of which collision events are determinable. The measured values are fed to an evaluator configured to determine the collision events by evaluating the time characteristic of the measured values in a controller.

A modular cutting tool includes a cutting head, a shank and a mechanism which assists in assembling and locks the cutting head to the shank. The cutting head includes a cutting portion rotatable about a central longitudinal axis and a cylindrical skirt extending axially from the cutting portion and terminating at a contact face disposed perpendicular to the longitudinal axis. The skirt has a number of curved inner surfaces which generally define a bore disposed about the longitudinal axis. The shank includes a cylindrical portion of a first diameter disposed about the central longitudinal axis and a central protrusion disposed in the bore of the cutting portion. The central protrusion has a second diameter less than the first diameter and extends longitudinally from a contact face disposed perpendicular to the longitudinal axis at a leading end of the cylindrical portion.

This disclosure relates to a tool guide for a tool that shapes a workpiece. The tool guide may include a body having a contact surface configured to contact a surface of a workpiece, a tool holder positioned within the body and configured to hold a machining tool having a tool bit, the tool holder holding the machining tool in a predetermined orientation relative to the workpiece, a guide element attached to the body configured to engage a surface feature of the workpiece, and an upper opening and a lower opening in the body configured to allow the tool bit to extend beyond the contact surface and operate to remove a portion of the workpiece.

A machining assistance system for assisting a machining apparatus includes: a workpiece supporting force generating unit, which generates workpiece supporting force against machining reaction force that is exerted on a machining portion of a workpiece by a working tool; a supporting device, which moves the supporting force generating unit while supporting the supporting force generating unit; and a workpiece supporting force control device, which controls operation of the workpiece supporting force generating unit and operation of the supporting device based on machining reaction force related data related to the machining reaction force and machining position related data related to a machining position of the working tool, such that the workpiece supporting force generating unit exerts the workpiece supporting force on the workpiece against the machining reaction force.
