A machining-detecting synchronous machine profile error online compensation method and system
This invention discloses an online contour error compensation method and system for a machining-inspection synchronized machine tool, belonging to the field of CNC related technology. It constructs a generalized tool space kinematic model including the spindle, tool, and scanning probe, establishing the transformation relationship between the probe coordinate system and the tool coordinate system; plans the cooperative trajectory of the tool machining path and the probe scanning path, avoiding the probe in non-inspection areas and constraining its posture and feed rate in the inspection area; during machining, it collects workpiece contour point cloud data in real time, maps it to tool tip coordinates using the transformation relationship, reconstructs the actual contour surface, and calculates its contour error compared to the desired surface; it decouples the error into servo axis components, generates axis compensation commands, and corrects the servo drive signals to achieve real-time closed-loop compensation. This invention solves the problem of difficulty in synchronizing online inspection and error compensation in complex surface machining, realizing real-time contour accuracy control under integrated machining-inspection.

A high-speed detection label changing equipment label rejecting automatic compensation mechanism and a compensation method
ActiveCN120228065BActively change lengthCompensate for tension changesControl engineeringControl theory
The application relates to the technical field of detecting and replacing labels, and particularly relates to a high-speed detecting and replacing label equipment label rejecting automatic compensation mechanism and a compensation method. The application provides a passive tension compensation scheme based on a lever transmission principle, a lever structure with a specific proportion is connected between a label rejecting sliding piece and a tension compensation guide roller, the lever moment balance characteristic is utilized, and synchronous linkage of label rejecting action and tension compensation is realized; specifically, when the sliding piece moves downward to reject a label, the movable guide roller is automatically driven to move upward by an equal distance through a lever transmission structure composed of a first swing rod and a second swing rod, so that the paper path length is actively changed, and the tension change caused by label rejection is compensated.
