“…To date, studies on the manufacturing of miniature gears have focused mainly on the processing of involute spur gears. Micro-hobbing 6 and micro-milling 7 are the traditional methods. However, burr problems exist in micro cutting, 8 which makes miniaturization difficult.…”

Miniature gears have important research value and application prospects in micro-scale machinery. The existing manufacturing methods for miniature gears produce spur gears on the micron scale and spur, helical and bevel gears on the millimetre scale. However, there is no mature process for gears on the micron scale for angular transmissions, such as bevel gears. This article reports for the first time the micro-machining of a miniature bevel gear with an external size of 1–2 mm based on a novel gear structure: the bevel line gear. First, a novel manufacturing method, namely the two-step method of nanosecond pulse laser ablation (NSPLA), is proposed. Then, a sample of a miniature bevel line gear is fabricated from 6061 aluminium alloy with a top angle of 90°, external diameter of 1375 μm, tooth number of 3 and average tooth width of 20 μm. Finally, the accuracy of the sample is studied to confirm the practicability of the proposed method.

The utilization rate of miniature gears has increased sharply with the widespread application of micro-pumps, electronic equipment, and measuring instruments, and therefore the design and processing of miniature gear has become a subject of intense research. Current research has predominantly focused on machining miniature parallel-axes gears, but well-established machining methods for miniature intersecting-axes gears are still lacking. This paper presented a nanosecond pulsed laser micro-milling technology for miniature intersecting-axes gear (MIAG). Firstly, the 3D models of driving MIAG and driven MIAG were established, and the machining schemes were proposed on the basis of the characteristics of the models. Then, the influences of processing parameters such as defocusing distance, pulse overlap, and scanning strategy on the output responses, including removal rate, surface roughness, and shape accuracy were analyzed. Afterward, some miniature structures, such as miniature grooves, cylinders and cones, were machined by combining these process parameters. Finally, the MIAGs were machined, and the accuracy evaluation and kinematics experiment were carried out. The diameter of driving MIAG was 1.21 mm, and the diameter of driven MIAG was 3.389 mm. The experimental results indicate that the proposed machining technology can process MIAG with relatively high precision and can also offer a valuable reference for the manufacturing of other miniature components.
