    Abstract: A cutting head rotatable about a head axis has a pair of first cutting arms circumferentially alternating with a pair of second cutting arms. Each first cutting arm has a radially extending first cutting edge, which includes a first radially outer and a first radially inner cutting-edge portion. The first radially inner cutting-edge portion defines an imaginary first circle having a first diameter, and has a first inner cutting profile. Each second cutting arm has a radially extending second cutting edge. The second cutting edge defines an imaginary second circle having a second diameter, and has a second cutting profile. The first diameter is greater than the second diameter, and the first inner cutting profile is identical to the second cutting profile. A rotary cutting tool has an elongated tool shank and the cutting head of the type described above disposed at a front end of the tool shank.

  • Publication number: 20240390992
    Abstract: A split hole saw bit designed for efficiently cutting circular holes in wood and simplifying the removal of the cut portion of wood (i.e., plug) from within the saw bit is disclosed. The bit comprises first and second semi-cylindrical members that, when assembled, form a circular bit equipped with cutting teeth at their bottom ends for initiating and performing the cut. A center pilot bit extends below the circular bit, designed to drill ahead, thereby facilitating the start of the cutting operation. The semi-cylindrical members are secured together using a nut having an integrated stopper which secures the semi-cylindrical members and prevents vertical movement of the center pilot bit during use. The drill head of the center pilot can be used with any drill and the bit enables easy detachment of the semi-cylindrical members for quick removal of the wood plug.

  • Publication number: 20240391024
    Abstract: Techniques are disclosed for a liquid jet laser tool that employs an off-axis laser beam and a liquid jet stream ejected from a nozzle. The off-axis design allows the beam to be directed into the jet stream from a lateral position at an angle of incidence that causes it to propagate/travel internally within the jet stream. Any requisite optics are employed to direct the laser beam into the jet stream. The laser beam thus confined in the liquid jet stream arrives at a workpiece. The off-axis design prevents the damage to the nozzle by the laser, and thus minimizes/eliminates the need for its replacement thereby increasing efficiency and reducing operational costs. In embodiments, multiple laser beams are directed into the jet stream that simultaneously propagate within the jet stream to arrive at the workpiece. The multi-laser design accrues benefits including more uniform laser energy, higher peak power, reduced maintenance, and the like.

  • Publication number: 20240391026
    Abstract: Techniques are disclosed for a liquid jet laser tool that employs an off-axis laser beam and a liquid jet stream ejected from a nozzle. The off-axis design allows the beam to be directed into the jet stream from a lateral position at an angle of incidence that causes it to undergo total internal reflection within the jet stream. Any requisite optics are employed to direct the laser beam into the jet stream. The laser beam thus confined in the liquid jet stream arrives at a workpiece. The off-axis design prevents the damage to the nozzle by the laser, and thus minimizes/eliminates the need for its replacement thereby increasing efficiency and reducing operational costs. In embodiments, multiple laser beams are directed into the jet stream that simultaneously undergo total internal reflection to arrive at the workpiece. The multi-laser design accrues benefits including more uniform laser energy, higher peak power, reduced maintenance, etc.

    Abstract: A method of laser ablation of one or more holes in an article includes a step of establishing an ablation characteristic. The ablation characteristic is a laser characteristic, a working zone characteristic, a cooling hole characteristic, or a synchronized machine motion characteristic. A creating step creates a laser path plan for a laser beam based on the established ablation characteristic for a first working zone and a second working zone of the article. An ablating step ablates the first working zone with a first ablation characteristic and afterwards ablates the second working zone with a second ablation characteristic which is different from the first ablation characteristic.
