AI Technical Summary
In CNC machining workshops, fluctuations in ambient temperature cause aluminum alloy panel parts to stretch and deform, affecting processing quality and product qualification rate. Existing methods are time-consuming and costly, and also affect aircraft assembly progress and quality.
By analyzing the impact of ambient temperature changes on part elongation, machining variables are defined, and the thermal expansion coefficient and temperature compensation coefficient of the computer tool system are measured. Data is collected using a laser tracker and temperature sensors, processed by a server, and transmitted to the CNC control system for temperature compensation, thereby achieving part elongation compensation.
It enables real-time temperature compensation for the workpiece and machine tool system before the first part is processed, simplifying operation, shortening cycle time, improving accuracy, ensuring part quality, and reducing quality problems caused by temperature changes.
