Abstract
Dynamic properties of the air gauges performing in-process measurement are of the great importance because of dynamic error affecting the measurement results. The paper presents the analysis of the air gauges dynamics and some practical recommendation. The investigations proved the dependence of the time constants on the actually measured back-pressure. In practical solutions of in-process control, the air gauge must work in conditions of falling back-pressure since with the material removal dimensions of the machined workpiece go down. Thus, in the area of the smallest values of back-pressure within the measuring range, the time constant value is the largest. Worsening of the air gauge dynamic properties at the end stage of the machining must be considered when the dynamic characteristics of the projected air gauge are calculated.
Highlights
In-process measurements ensure high productquality through real-time quality monitoring, reduce manufacturing costs and increase productivity (Berger et al, 2015)
Automated quality control is very important aspect of a manufacturing process (Milo et al, 2015), and the measurement accuracy is important in the new manufacturing era called Smart Manufacturing, Intelligent Factory or Industry 4.0 (Moroni & Petro, 2018)
This study is dedicated to the accurate determination of the time constant, which is crucial in in-process measurement with air gauges
Summary
In-process measurements ensure high productquality through real-time quality monitoring, reduce manufacturing costs and increase productivity (Berger et al, 2015). Automated quality control is very important aspect of a manufacturing process (Milo et al, 2015), and the measurement accuracy is important in the new manufacturing era called Smart Manufacturing, Intelligent Factory or Industry 4.0 (Moroni & Petro, 2018). To handle metrological data in multistage manufacturing processes, intelligent systems based on neural networks are applied (Papananias et al 2019). Application of piezoresistive transducers and small chambers was desribed by Rucki et al (2010), it reduced the time constant and setting time down to few milliseconds (Rucki & Jermak, 2012). This study is dedicated to the accurate determination of the time constant, which is crucial in in-process measurement with air gauges
