摘要： A tailstock for supporting a workpiece along a vertical rotary axis includes a base member, and a housing having a wall including a first end, and a second end, an outer surface, and an inner surface defining a central passage extending between the first and second ends defining a longitudinal axis. The second end is coupled to the base member. A workpiece support extends through the central passage. The workpiece support includes a first end, a second end and an intermediate portion extending therebetween. A linear bearing is coupled to the base member in the central passage. The linear bearing slideably receives the second end of the workpiece support. A displacement sensor assembly includes a stationary portion mounted relative to one of the base member and the housing, and a moveable portion mounted to the second end of the workpiece support.

摘要： A method of controlling a production process includes illuminating a portion of a workpiece undergoing a production process with a light having a selected wavelength, processing a portion of the workpiece, capturing a digital image of the light reflecting from a surface of the workpiece with a digital camera, performing, with a processor, a specular reflectance analysis of the digital image, and adjusting a production process parameter based on the specular reflectance analysis.

摘要： An earth-boring bit has at least one steel tooth with a scoop-shaped profile. The scoop-shaped profile is formed by milling and hardfacing a tooth to have at least one flank with a concave profile. Additionally, the tooth may contain one flank with a concave profile and another with a convex profile. The centerline axis of the tooth may be moved to alter the angle between the flanks and the centerline to vary the manner in which the tooth engages the formation.
