“…However, the solid drill has a large amount of material removal during hole processing, which generates a large axial force, so some scholars proposed the ''grinding instead of drilling'' method, using a hollow-type trepanning bit to drill holes in the form of grinding. Ozturk S 19 studied the hole processing of CFRP using an electroplated diamond trepanning bit and found that the trepanning bit could obtain a large critical axial force, which was beneficial to reducing the generation of delamination defects. According to the research above, a tool's structure and material will have an impact on how well a workpiece is machined, and a well-designed tool will significantly enhance the quality of the hole.…”

Glass Fiber Reinforced Plastic is widely used in manufacturing and other fields because of its high specific strength and high specific modulus. Since the workpiece requires secondary hole processing during assembly, machining defects are prone to occur during hole making, which seriously affects the service life of the workpiece. A novel type of thin-walled diamond trepanning bit was fabricated and combined with ultrasonic processing technology to conduct a pilot study on hole processing. Compared with conventional twist drill hole processing, the novel diamond trepanning bit grinding hole-making method can significantly reduce the axial force when drilling, and effectively reduce the delamination and tearing damage at the exit of the hole, so that the delamination ratio at the exit is reduced by 9.6%. Combined with ultrasonic machining technology, hole machining experiments were carried out, and the results showed that: spindle speed increase or feed rate reduction can make axial force, hole wall surface roughness, and exit delamination damage all show a decreasing trend. Compared with conventional machining, the rotary ultrasonic hole machining technology can effectively reduce the axial force by 20.1% and effectively reduce the exit delamination problem by 7.3% in the delamination ratio. At the same time, considering the hole-making quality and efficiency, rotary ultrasonic processing can better reflect the advantages of the process and obtain better hole-making quality at the speed of 3000–4000 r/min and the feed rate of 14–20 mm/min. The above research can provide theoretical and technical support for the hole processing problems of Fiber Reinforced Plastic, which has important engineering application value.

Flat glass has a significant utilization in the domestic appliances sector. Drilling of glass is frequently used in the white goods sector. In this research, the glass drilling method is explained in detail, the determined axial misalignment values using the tool rotation speed and the feed rate were investigated. The drilling operation with its parameters must be optimized precisely, in order to have good control over the productivity, quality, and cost aspect of the application. Using the Ø18.3 mm drill tool, drilling process was performed with different rotation speeds (rpm) and feed rates (mm/sec). The impressions of drilling parameter on output variable were investigated using Analysis of Variance (ANOVA). Probabilistic uncertainty analysis based on Monte Carlo simulation was carried out. According to the results, the suggested model and optimization method could be used for estimating axial misalignment and this investigation is reliable and proper for figuring out the problems met in machining operations. Furthermore, Monte Carlo simulations were obtained quite effective for identification of the uncertainties in axial misalignment that could not be possible to be caught by deterministic ways. The optimum axial misalignment value was found to be 0.11823 mm.
