Abstract
A system and method for machining an elongate workpiece in a plurality of work cells are provided. The work cells are positioned along a substantially linear process flow path so that the work operations can be performed on different lengthwise portions of the workpiece simultaneously. A transport system advances the workpiece from an infeed system along the process flow path, thereby moving the lengthwise portions of the workpiece successively through the work cells. The transport system includes a plurality of pallets that can be engaged to the workpiece so that the workpiece is supported by the pallets throughout at least part of the machining system.
Claims36
A method for machining an elongate workpiece, the method comprising:
- engaging a plurality of pallets to the workpiece such that the workpiece is configured to be supported by the pallets;
- advancing the pallets and the workpiece along a substantially linear process flow path so as to successively move each of a plurality of lengthwise portions of the workpiece to a plurality of work cells spaced along the flow path at distances shorter than a length of the workpiece;
- immobilizing and stabilizing the workpiece in a plurality of incremental positions along the flow path, the workpiece in each position being disposed in at least two of the work cells;
- and
- performing at least one work operation on different lengthwise portions of the immobilized workpiece in each of the work cells.
A method for machining an elongate workpiece, the method comprising:
- engaging a plurality of pallets to the workpiece such that the workpiece is configured to be supported by the pallets;
- supporting the pallets and the workpiece by a plurality of rollers positioned along a substantially linear process flow path and advancing the workpiece along the rollers along the process flow path so as to successively move each of a plurality of lengthwise portions of the workpiece to a plurality of work cells spaced along the flow path at distances shorter than a length of the workpiece;
- immobilizing and stabilizing the workpiece in a plurality of incremental positions along the flow path, the workpiece in each position being disposed in at least two of the work cells;
- and
- performing at least one work operation on different lengthwise portions of the immobilized workpiece in each of the work cells.
A method for machining an elongate workpiece, the method comprising:
- engaging at least one clamp device of each of a plurality of pallets to a grip feature of the workpiece such that the workpiece is configured to be supported by the pallets,
- advancing the workpiece along a substantially linear process flow path so as to successively move each of a plurality of lengthwise portions of the workpiece to a plurality of work cells spaced along the flow path at distances shorter than a length of the workpiece;
- immobilizing and stabilizing the workpiece in a plurality of incremental positions along the flow path, the workpiece in each position being disposed in at least two of the work cells;
- performing at least one work operation on different lengthwise portions of the immobilized workpiece in each of the work cells;
- and
- machining the workpiece to remove the grip feature from the workpiece.
A method for machining an elongate workpiece, the method comprising:
- engaging a plurality of pallets to the workpiece such that the workpiece is configured to be supported by the pallets;
- advancing the workpiece along a substantially linear process flow path so as to successively move each of a plurality of lengthwise portions of the workpiece to a plurality of work cells spaced along the flow path at distances shorter than a length of the workpiece;
- immobilizing and stabilizing the workpiece in a plurality of incremental positions along the flow path, the workpiece in each position being disposed in at least two of the work cells;
- performing at least one work operation on different lengthwise portions of the immobilized workpiece in each of the work cells;
- and
- machining a surface of the workpiece extending in a first plane in one of the work cells and machining a surface of the workpiece extending in a second plane generally perpendicular to the first plane in a different work cell.
A method for machining an elongate workpiece, the method comprising:
- engaging a plurality of pallets to the workpiece such that the workpiece is configured to be supported by the pallets;
- advancing the workpiece along a substantially linear process flow path so as to successively move each of a plurality of lengthwise portions of the workpiece to a plurality of work cells spaced along the flow path at distances shorter than a length of the workpiece;
- immobilizing and stabilizing the workpiece in a plurality of incremental positions along the flow path, the workpiece in each position being disposed in at least two of the work cells;
- and
- performing at least one work operation on different lengthwise portions of the immobilized workpiece in each of the work cells,
- wherein said immobilizing and stabilizing step comprises contacting and positioning the pallet in at least one of the work cells, thereby positioning the workpiece in a desired configuration, and contacting the workpiece in at least one of the work cells such that a grip feature of the workpiece is accessible for machining.
