Abstract:
The invention consists in a drill press table or the like having a plate. The plate has thereon means to receive an elongated member and there is a selected position on the plate such as an aperture in the plate. The longitudinal axis of the aperture passes through substantially a mid point of the means to receive an elongated member, and the aperture is positioned in the plate such that when the plate is correctly mounted on a drill press the aperture is, or can be, placed such that the longitudinal axis of the drill bit is substantially co-incident with the longitudinal axis of the aperture.
Abstract:
An automatic fastening machine (10) and method which reduces fastener installation cycle time by virtue of unique tool movement, pressure foot (204) operation and other features. The pressure foot plate (202) is coupled to actuators for moving the same in a manner allowing tilting of the plate relative to the plane of the workpiece during movement from one fastener installation location to another. The actuators are independently operated by a servo control arrangement (464) in conjunction with the machine control (460). As a result, it is not necessary for the system to seek a new down position thereby saving machine cycle time.
Abstract:
An automated bore finishing process particularly adapted for lapping automatically corrects one or more bore parameters, such as diameter, geometry, surface finish, in an iterative manner to reach a final value, controlled by algorithms that process feedback from a measurement process. The process determines bore parameter information and determines an optimum set of values for the process parameters, such as stroke position, stroke length and duration of the next lapping iteration. This optimization is targeted to achieve the desired final bore parameter or parameters within the specified bore size limits, and may be used to alter the stroke profile either for the entire next iteration or in a continuously changing manner, to minimize or eliminate bore defects over one or a succession of iterations.
Abstract:
An apparatus, system, and method using an elastic biasing element in combination with an encoder arrangement for precise control of force or torque applied to a moving object, is applied for controlling a feed force applied to an abrasive element of a bore finishing tool, to respond to changes in the feed force such as can arise from contact with a workpiece bore surface and variations therein, such as tapers, hourglass shapes, barrel shapes, and the like. The elastic biasing element can include a single or multiple springs in one or more sets, and the feed force can be selected to have a constant value or vary as a function of time, position, or other variables or conditions.
Abstract:
In the pocket hole apparatus (10) of the present invention, a table (14) reciprocates linearly (22) relative to a base (12). An anvil (16) is fixed relative to the base (12) and holds the workpiece (2) on a sloped top surface (102) at the desired angle for the pocket hole (4). A drill spindle (18) with a drill bit (30) is fixed relative to the table (14). After the workpiece (2) is mounted to the anvil (16), the table is moved to drill the pocket hole. Optionally, a second spindle (20) on the opposite side of the anvil (16) predrills the pocket hole (4) when the table (14) is first moved to a predrill position (28). The spindle (18) is enabled or disabled by a latching mechanism (44). The spindle (18) is mounted to a rail (40) that is slidably mounted to the table (14) so that the rail (40) can slide perpendicularly (42) thereby adjusting the spacing between pocket holes ( 4).

Abstract:
A grinding wheel system (16) includes a grinding wheel (18) with at least one embedded sensor (20a-20k, 22a-22d). The system (16) also includes an adapter disk (24) containing electronics (50) that process signals produced by each embedded sensor (20a-20k, 22a-22d) and that transmits sensor (20a-20k, 22a-22d) information (62) to a data processing platform (25) for further processing of the transmitted information (62). The data processing platform (25) uses a neuro-fuzzy network (160a) to process data from the electronics (50).
