“…When the ratio of cut to the cutting-edge radius is small, plowing dominates the cutting process rather than shearing, resulting in high biaxial compressive stresses that push material toward the free surface and generate large-top burrs. Also, the path the tool follows when entering or exiting the work surface also significantly affects burr formation [38,39]. The cutting parameters, workpiece material properties, tool geometry, coatings, and coolant lubricants also affect the burr formation significantly micro-milling [41].…”

“…Additionally, granite with a density of 2.8 kg/dm 3 is beneficial. According to Uriarte et al [38] we are using small tools; the spindle must rotate at high revolutions (<30,000 rev/min) to achieve the adequate cutting speed for most materials. Apart from the speed, the spindle must be stiff (>25 N/μm) and must present a small run out (<1 μm) to ensure high precision in the cutting process.…”

Micromachining has emerged as a foundational technology in modern electronics, playing a crucial role in the creation of miniaturized and high-performance devices. Its significance is particularly pronounced in the domains of high-frequency RF devices and Terahertz communication, where the demand for precision, miniaturization, and performance enhancement is of utmost importance. The requirement of linear tolerances are of the order of 1–5 μm, surface toughness of 40–50 nm Ra and flatness of 0.3 μm.

“…However, this definition focuses only on the tool and does not incorporate the important aspects of the machining process, namely precision, accuracy, and underlying material removal mechanism. Therefore, a more technical approach to characterize the micro-milling process can be as follows: a precision mechanical cutting process with geometrically defined cutting edge tool diameters of less than 1 000 µm for precise material chip removal to within less than 1 µm tolerance on form and dimensional accuracy [ 5 ].…”

Precision micro-milling process: state of the art

Micro-milling is a precision manufacturing process with broad applications across the biomedical, electronics, aerospace, and aeronautical industries owing to its versatility, capability, economy, and efficiency in a wide range of materials. In particular, the micro-milling process is highly suitable for very precise and accurate machining of mold prototypes with high aspect ratios in the microdomain, as well as for rapid micro-texturing and micro-patterning, which will have great importance in the near future in bio-implant manufacturing. This is particularly true for machining of typical difficult-to-machine materials commonly found in both the mold and orthopedic implant industries. However, inherent physical process constraints of machining arise as macro-milling is scaled down to the microdomain. This leads to some physical phenomena during micro-milling such as chip formation, size effect, and process instabilities. These dynamic physical process phenomena are introduced and discussed in detail. It is important to remember that these phenomena have multifactor effects during micro-milling, which must be taken into consideration to maximize the performance of the process. The most recent research on the micro-milling process inputs is discussed in detail from a process output perspective to determine how the process as a whole can be improved. Additionally, newly developed processes that combine conventional micro-milling with other technologies, which have great prospects in reducing the issues related to the physical process phenomena, are also introduced. Finally, the major applications of this versatile precision machining process are discussed with important insights into how the application range may be further broadened.
