Abstract: There may be provided a machining monitor that may include (i) a sensing unit that comprises a thermal sensor, (ii) a processor, (iii) a communication unit, and (iv) a housing. The thermal sensor is configured to (a) thermally sense a sensed region related to the machining during a machining, and while being rotated by a mechanical coupling to a rotation of a cutting tool, and (b) generate thermal detection signals. The processor is configured to determine a temperature parameter related of the sensed region based on the thermal detection signals.

Abstract: A milling head includes a milling head base, a plurality of blades annularly arranged around the milling head base; and an actuator to rotate the milling head base. Each of the plurality of blades extends from the base at a differential radial distance as compared to a neighboring blade from the plurality of blades.
