摘要： In one aspect of the invention, a drilling assembly comprises a head located on a rotational axis of the assembly and comprises at least one head element. At least one blade extends distally from the head. A plurality of blade degradation elements are rotationally supported on the blade. Each degradation element comprises an attack angle that affects the penetration rate of each degradation element and a laterally offset angle that primarily affects the rotational rate of each degradation element within their holders. The drilling assembly comprises a central cutting region. The blade degradation elements within the central cutting region form an attack angle of 15 to 20 degrees with the rotational axis of the drilling assembly.

摘要： In one aspect of the invention a system for removing a layer of a paved surface comprising a vehicle is adapted to traverse a paved surface in a selected direction. The vehicle has a milling drum with an axle substantially parallel and connected to the vehicle within a milling chamber. The drum is adapted to rotate around the axle between the paved surface and the vehicle. A conveyor belt is attached to a forward end of the vehicle and comprises a portion proximate an opening of the milling chamber. The belt is adapted to carry loose aggregate from the milling drum away from the paved surface. At least one nozzle is disposed on an underside of the vehicle and is in communication with a reservoir through a pathway. The at least one nozzle is adapted to direct the loose aggregate towards the portion of the conveyor belt.

摘要： A fixture for holding a cutter for a vertical turret lathe may comprise a block with a blind hole. A cutter with an indenter on its distal end may be secured within the hole such that a portion of the indenter comprises a positive rake angle.A method for testing cutters may comprise securing a cutter on a fixture of a vertical turret lathe which has a cutting material positioned adjacent the cutter. The cutting material may be rotated around a rotational axis at a constant rotational velocity. The fixture may be urged laterally such that the cutter progressively moves towards a periphery of the cutting material. The rotational velocity may be decreased as the cutter moves laterally to maintain a relative constant linear velocity between the cutting material and the cutter.
