The wear status of a micro-endmill tool may be inferred by monitoring the chip production rate of the tool in operation. Chips may be extracted from a work area, captured on an adhesive surface, imaged, and counted to determine the chip production rate. When the rate of chip production falls, the feed rate of the micro-endmill may be modified to a level suitable for the current state of tool wear. In this manner, costly and inconvenient work stoppages to evaluate the wear status of a tool are eliminated.

A machining center for performing a plurality of machining operations, such as drilling, milling, cutting, using rotating tools, on metal profiles having a longitudinal extent greater than their cross-section dimension, particularly but not exclusively made of aluminum. The machining center comprises a base defining a work surface extending longitudinally with first and second ends, upon which the profile is manually laid by an operator or by a specially-designed automatic feeder. The base has a plurality of members thereon for supporting and locking the profile, as well as a pair of vertical columns for supporting motorized spindles, each column being located next to said base and being configured to being displaced in either direction, parallel to the longitudinal extent of the base along respective slide guides located next to said base. Each vertical column is equipped with a first carriage configured to vertically sliding in either direction along its respective column and with a second carriage mounted to the first carriage, and configured to sliding in either direction perpendicular to its respective column. The center also comprises a portal structure whose upper beam above said base is equipped with a motorized spindle for rotating tools, mounted to a support body configured to angular displacements around a pivot for rotating about a first axis parallel to the longitudinal extent of the base.

A machine tool includes a stationary machine frame, a tool head, which is able to be positioned relative to the machine frame along three mutually orthogonal translation axes, and a motor-driven tool. The machine tool includes a swivel unit, which can be pivoted about a horizontal swivel axis relative to the machine frame and includes a workpiece positioning device, via which a workpiece can be rotated about an axis of rotation oriented perpendicularly to the swivel axis. The swivel unit is assigned a measuring frame, which is able to be rotated with the swivel unit and is arranged to be thermally and/or mechanically decoupled from the swivel unit and includes components of a first and second position measuring system. Additional components of the first position measuring system are disposed on the tool head, and further components of the second position measuring system are situated on the workpiece positioning device. The spatial position of the tool head in relation to the measuring frame is ascertained via the first position measuring system, and the spatial position of the workpiece positioning device in relation to the measuring frame takes place via the second position measuring system.
