Abstract: A parting tool is in the form of a blade and a replaceable cutting insert, as well as, a key having an eccentric body. The cutting insert may be clamped in a seat under an elastic, resilient clamping finger. In the blade, a keyhole is formed, into which the eccentric body can be inserted. In the keyhole, there are included concave sliding surfaces, which border on a flat stop surface. With these, convex corner surfaces and flat shoulder surfaces on the eccentric body can interact. By the unique design of the keyhole and eccentric body, a gentle interaction between the surfaces is obtained, which guarantees a long service life of the blade, as well as the key.

Abstract: Air compressor systems, upgrade kits, computer readable medium, and methods for controlling an air compressor for improved performance. The methods may include receiving a working air requirement; determining an estimated air pressure of the air compressor to deliver the working air requirement; measuring a pressure of the air compressor; comparing the measured pressure with the calculated estimated air pressure; if the measured pressure of the air compressor is greater than the determined estimated air pressure by a predetermined greater amount, then decreasing an output control of the air compressor; and if the measured pressure of the air compressor is less than the calculated estimated air pressure by a predetermined lesser amount then increasing the output control of the air compressor. The air compressor may be controlled based on a measured pressure of delivered working air. An oil control system may shut off oil to parts of the air compressor.
