For cutting a large screw, the cutting force and temperature have direct impact on machined surface quality, such as accumulated pitch error in geometric error. Excited by cutting force, the axial deflections directly affecting accumulated pitch error were studied based on the beam theory. By experiments, the axial cutting force was predicted with a 96% confident interval, and the tool number and cutting depth were found to be significant terms. Tested under increasing cutting speeds, the temperature rise of workpiece and accumulated pitch error both decreased obviously. Thus the higher cutting speed could improve the cutting precision of a full-length large screw.

“…1B). Especially for brittle materials such as engineering ceramics, there are crystal gaps, tiny cracks, and different sizes of internal grain [24,25]. In the actual machining process, when the ceramic material is impacted, the surface and sub-surface cracks propagate, and the chips formed by the envelope of the cracks and the unmachined surface flow out [26].…”

The characteristic frequency of vibration was obtained by extracting the vibration characteristics of fluorophlogopite in quick-point grinding, and the characteristic frequency deviation rate was proposed to study the effect of vibration characteristics on surface roughness. Meanwhile, the influence of five process parameters, such as the grinding speed, table feed speed, grinding depth, deflection angle, and inclining angle, on the characteristic frequency deviation rate and surface roughness was also investigated. It reflected the relationship between deviation rate and surface roughness. The experimental results indicated that the process parameters influenced the deviation rate and surface roughness, and the changes of both were synchronized. Moreover, the modified model of the quickpoint grinding surface roughness was proposed in the paper, which was based on the prediction model of several scholars. The model included vibration characteristic parameters and five process parameters, which not only kept the accuracy of the prediction model but also realized the introduction of vibration characteristics. It was proved that the prediction effect of the modified model was accurate and reliable. Based on the prediction model of surface roughness including vibration features, the idea of monitoring and controlling surface roughness by real-time vibration signal was put forward.
