An inexpensive and reliable floating fastener is provided by manufacturing an integrated nutplate into the backside of the interior structural member. A retention clip engages the nutplate to capture the nut while allowing the nut to float. The integrated nutplate roughly aligns the floating nut to the axial through-hole in the structural member and provides the torque resistance required to drive the screw into the nut. The retention clip holds the nut in place and provides the axial resistance required for the lead chamfer of the screw to engage the nut and resist the axial loading on the screw during installation. The nutplate is designed to facilitate cost-effective manufacturing. The per hole cost of the integrated floating-fastener is approximately 30% of the cost of the industry standard riveted floating fastener.

A cluster mill blank includes a framework constructed to cooperate with a blank holder of an existing CAD / CAM system, and a plurality of sub-blanks attached to the framework forming an addressable matrix or cluster blank. CAD / CAM systems including such a framework, as well as associated methods are described.

To provide a mill that can greatly reduce noise during operation and can also contribute to greater device compactness. The mill is provided with: a tubular drum body configured in a manner so that a material to be milled introduced from one section can be discharged from another section; a central shaft that penetrates within the drum body in the direction of tube length thereof; and a plurality of milling plates that are attached at a predetermined interval in the axial direction of the central shaft, and that compartmentalize the interior space of the drum body in to a plurality of milling chambers. The drum body and / or the milling plates rotate, and the mill does not have a milling medium that mills the material to be milled by contacting the material to be milled while rolling within the drum body.

The invention belongs to the technical field of mechanical processing, and in particular relates to a multi-spindle electromechanical fully automatic adjustable wheelbase milling and drilling compound processing machine tool.

It effectively solves the increase of torque, increase of cutting force, increase of cutting heat, decrease of tool durability, chatter and impact in the cutting process.

The invention relates to an optimizing selection method of carbon fiber composite down milling and up milling machining manners and belongs to the technical field of machining. According to the optimizing selection method of the carbon fiber composite down milling and up milling machining manners, based on milling machining parameters, the actual change ranges of the fiber cutting angles in the milling process are correspondingly worked out, according to the properties of a utilized material and the utilized cutter structure, in an experiment or finite element calculation manner, the fiber cutting angle range enabling the machining quality to be the best is determined, the proportions of the condition that the actual ranges of the fiber cutting angles during down milling and up milling arewithin the optimal range are calculated finally, and the milling manner with the larger proportion is selected as the optimal milling manner under the working condition. By the adoption of the optimizing selection method, a new method can be provided for achievement of high-quality high-efficiency high-precision milling of a carbon fiber composite component, optimizing selection of the milling manners is achieved, the calculation steps are simple and convenient, and the optimizing selection method has good engineering application prospect.

The invention aims to provide a method for processing rigid structure parts through digital control and a clamp structure for processing the rigid structure parts through the digital control. The method mainly comprises the following steps: performing rough machining on part blanks, processing a plurality of process lug bosses with the equal height on the periphery of the contour surface of the parts in the process of the rough machining, and processing a rigid connecting bridge between the process lug bosses and the contour surface of the parts to make the process lug bosses connected with the contour surface of the parts continuously. The process lug bosses are evenly distributed on the periphery of the contour of the parts according to the differences of the part structures, and the weaker parts of the part structures are provided with more process lug bosses properly. One of the advantages of the method is to use the process lug bosses combined with the parts to replace special fixtures so as to save the manufacturing cost.
