A rotary cutting method includes producing a processed product by rotary cutting of a workpiece by a rotary tool. The rotary tool has at least one cutting edge of which both of a first rake angle in a rotation radial direction and a second rake angle in a rotation axis direction are negative. The at least one cutting edge has a slanted face connected with a rake face forming the first and second rake angles. The slanted face is connected with the rake face at a ridge line. The slanted face faces a rotating direction of the rotary tool. An angle of the slanted face to the rotation axis direction is positive.

A rim drilling and milling machine has a bottom base, a table, and a clamping unit. The clamping unit is fixed on the table and has a clamping base and multiple clamping members. Each clamping member has at least one jaw each having a jaw body, a clamping groove recessed in the jaw body, and an abutting protrusion formed between a top surface of the jaw body and the clamping groove. A distance defined from a bottom surface of the clamping groove of each of the at least one jaw to a bottom surface of the bottom base ranges from 850 millimeters to 1000 millimeters. The rim drilling and milling machine can firmly and stably clamp a wheel rim, and the wheel rim can be clamped at a position for a user to easily see a processing area of the wheel rim.

In one example, an on-wing method for in-situ cutting on a wing-to-fuselage attachment includes attaching a first mount plate having a first linear bearing to provide movement in a first linear direction relative to the first mount plate, attaching a second mount plate having a second linear bearing to provide movement in a second linear direction relative to the second mount plate, attaching a tool mounting member to the second linear bearing to move with the second linear bearing, attaching a cutter to the tool mounting member to be adjustable relative to the second linear bearing, adjusting a depth position of a cut to be made on the wing-to-fuselage attachment, adjusting a width position of the cut, and moving the tool along a length direction of the cut to make the cut on the wing-to-fuselage attachment along the length direction at the adjusted depth position and the adjusted width position.
