摘要:
In order to measure the geometry of a workpiece surface (165) without contact, in particular in order to measure the geometry of substantially rotationally symmetrically curved workpiece surfaces on workpiece sections machined by means of honing or finishing, before, during, and/or after a fine machining process, a measuring system (150) comprising at least one measuring nozzle (152, 153) is used, said nozzle being attached to a tool (140) and being connected to a pressure fluid source (151) arranged at a distance from the measuring nozzle by means of a pressure fluid line (156, 157, 155, 154). The measuring nozzle is brought near the workpiece surface (165) in order to perform a measurement, and a property of the pressure fluid dependent on the distance (A) between the measuring nozzle and the workpiece surface is measured and is evaluated in order to determine the distance. In said measurement, a fluid flow of the pressure fluid flowing through the pressure fluid line to the measuring nozzle is measured by means of a flow sensor (170) and a sensor signal of the flow sensor is evaluated in order to determine the distance.
摘要:
In the honing method, multiple individual machining processes lead to downtime due to the tool change. The novel honing tool enables a multiple honing machining process by means of one tool without a change in the machining center. Depending on the position of a mechanical control slide (9), one or more further tool cones (5) are intermittently individually impinged upon by a non-solid medium in a pressure line (10) by means of a feed (8) and thus controlled. Said system can be used especially advantageously in machining centers (MCs).
摘要:
A honing method and honing control device (1) suitable for the honing having a large processing area is provided. The honing control device includes a grinder (7) and an expansion member for disposition in a processing hole of a workpiece. The amount of an expanding movement when the grinder contacts the inner surface of a gauge hole via the expansion member is stored as a target expansion amount by inserting a honing head (3) into the gauge hole having the same size as a target processing diameter of a master gauge (30). Then, a honing of an inner surface of the processing hole is performed by inserting the honing head within a processing hole (W1) of a workpiece (W) moving the grinder towards an outer side of a diametrical direction by the expansion member installed within the honing head to rotate the honing head. The honing is completed when the amount of the expanding movement of the grinder reaches a target expansion amount established by the master gauge.
摘要:
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.
