Abstract
A laser match honing system and method are provided for processing one of a pair of mechanically matching components (1, 2) having matching portions (12, 22, 16, 26) that will be fitted with each other. A dimension of the matching portion (12, 16) of the first component (1) is measured and is then used for calculating the desired dimension of the corresponding matching portion (22, 26) of the second component (2). An actual dimension of the matching portion (22, 26) of the second component (2) is also measured. Then, the matching portion (22, 26) of the second component (2) is honed by laser beam in the condition that the actual dimension is not equal to the desired dimension.
Claims20
A laser match honing system for processing one of a pair of mechanically matching components, the pair comprising a first component which has a finished matching portion and a second component which has a corresponding matching portion to be processed, the system comprising:
- a system controller for controlling the operation of the system,
- a measuring gauge coupled to the system controller and adapted to measure a dimension of the matching portion of the first component and send the measurement to the system controller,
- a supporting device adapted to carry the second component,
- a laser beam source coupled between a processing optic unit and the system controller and adapted to emit a laser beam to the processing optic unit when receiving a command from the system controller,
- an optical measuring instrument coupled between the processing optic unit and the system controller and adapted to emit a measuring light to the processing optic unit for measuring a current distance between the processing optic unit and the matching portion of the second component, and
- the processing optic unit being adapted to direct the laser beam and the measuring light onto the matching portion of the second component,
- wherein the system controller calculates a desired dimension and a real dimension of the matching portion of the second component based on the measurement from the measuring gauge and the measurement from the optical measuring instrument respectively, and then the system controller, when the real dimension is not equal to the desired dimension, operates the laser beam source to transmit the laser beam for honing the matching portion of the second component by the laser beam.
A laser match honing method for processing one of a pair of mechanically matching components, the pair comprising a first component which has a finished matching portion and a second component which has a corresponding matching portion to be processed, the method comprising:
- measuring a dimension of the matching portion of the first component,
- measuring a current distance between a processing optic unit and the matching portion of the second component,
- calculating a desired dimension and a real dimension of the matching portion of the second component based on the measured dimension and the measured distance respectively, and
- honing the matching portion of the second component by laser beam when the real dimension is not equal to the desired dimension.
