“…As the feed rate increases, the surface roughness of the worm increases, and the difference on the right side away from the feed direction is more significant than that on the left side, which is consistent with the research in the literature. 29 This is mainly since when the feed rate increases, the material removed per unit time increases, the enveloping times of the specific tooth profile decreases, and the height of the residual area of the machined surface increases. The feed rate change will produce different degrees of error in different positions, and the overall error is small (within 3 mm).…”

The profile of the hard whirling tool for ZC1 worm machining is challenging to design precisely. An inaccurate tool profile results in irreversible overcutting or additional machining allowance. This study aimed to develop an accurate tool profile design method and digital verification approach to enhance the quality of ZC1 worms. The precise measurement and axial section data acquisition of the worm are conducted. A tool profile design method is proposed based on the envelope of the equidistant axial section. The motion law of whirling is studied, and a 3D model generation procedure for worm teeth is developed. The effect of the tool profile design is verified, and the impact of cutting parameters on worm tooth profile error is analyzed. The results show that the presented tool design method can effectively avoid overcutting. The employed modeling approach of worm teeth provides an intuitive verification means for tool profile design. Variable cutting parameters lead to different machining errors, and the maximum error is less than 3 μm. Changing the cutting parameters will not induce macro profile error but will impact the micromorphology. These findings should be valuable for designing envelope machining tools with complex motion and realizing the superior performance of hard whirling for ZC1 worm machining.

“…24 Zhang et al 25 proposed a measurement method for high-precision cutting edge radius of diamond tools by atomic force microscope. Song et al 26 proposed a new method for hard whirling tool edge reconstructing based on fractal interpolation, in which the edge radius is measured and reconstructed in a section. Zhao 27 formulated a modelling and detection method for cutting edge radius, which could predict the radius precisely.…”

The optical measurement technology could reduce manual work and improve quality in assembly. The confocal scanning scheme is proposed to measure the narrow gap in-line but it is hard to identify the edges of a gap. This paper proposed an edge definition and presented an edge identification method for gap measurement. The edge profile is defined as a part of a circle, which could be identified by the shutter time feature. The defined edge point could be calculated by fitting the edge profile, and then the width of a gap section is calculated by two edge points. The width of a gap can be evaluated by the average of several gap section. The experimental results indicate that the repeatability of the method is less than 2 µm and the precision of the measurement is higher than ±2.5 µm. The proposed method is feasible for in-line measurement application in assembly.
