The present application belongs to the field of furniture production and manufacturing, and provides a wood material cutting tool wear and machining precision online monitoring method, which comprises: sharpness determination and wear amount calculation and analysis of handle milling cutter and drill bit; preparing test materials and tools, determining numerical control milling machine and measuring instrument equipment; based on the tool edge retreat amount on the tool wedge angle diagonal, as the cutting tool edge wear evaluation value; tool wear test; multi-source signal synchronous acquisition and signal preprocessing and noise reduction; multi-domain feature extraction and fusion; optimization algorithm suitable for tool wear prediction model establishment: constructing LF-SMA-RELM tool state monitoring and prediction hybrid model for predicting tool edge retreat amount; online monitoring and intelligent early warning; the present application realizes full-process monitoring and prediction of cutting tool wear state and machining precision change.

Method and apparatus for centralized compliance, operation and setup of automated cutting tool machines. A system (100) and method for cutting at least one feature (118) in a workpiece (116) with at least one cutting tool (114) of a plurality of cutting tools (114) controlled by at least one cutting tool machine (104) of a plurality of cutting tool machines (104) is disclosed. The method receives process information from a cutting tool machine (104) describing cutting parameters, retrieves predictive cutting tool wear information relating predicted cutting tool wear values to the cutting parameters, retrieves cutting tool information including measured cutting tool wear information for the one cutting tool (114) of the plurality of cutting tools (114), calculates a predicted cutting tool wear value for the one cutting tool (114) of the plurality of cutting tools (114) from the measured cutting tool wear information, and cuts the at least one feature (118) according to the calculated predicted cutting tool wear value.

The utility model discloses a kind of gas expansion axle connecting structures of cutting table, including bottom plate, protective strip and axle body;The surface of the axle body is slidably connected with top rod, the end of the top rod is fixedly connected with gas expansion strip, the number of the gas expansion strip is four, the surface of each gas expansion strip is provided with a plurality of clamping grooves, the inside of the protective strip is provided with clamping groove, the end of the clamping groove is equipped with limit plate, the clamping groove is connected with clamping strip snap connection.The utility model sets detachable protective strip on the surface of gas expansion strip, when cutting roll, it can avoid cutting tool wear, gas expansion axle both ends in the utility model can be supported, to avoid protective film to shake when rotating, improve cutting surface flatness, the utility model can first carry out the fixation of gas expansion axle, then gas expansion axle is connected with cutting table, to improve the concentricity of film roll and gas expansion axle.
