- The paper explores the complex process of surface texture formation in milling, focusing on the surface roughness of X37CrMoV51 steel during shoulder milling.
- A mathematical model was developed to predict the surface roughness parameter Ra, which includes factors like feed per tooth, corner radius, and the number of inserts used in the cutting process.
- The study found a high correlation (0.96) between theoretical predictions and experimental data, revealing that cutting efficiency changed with varying feed rates and cutting speeds.
Drilling with standard twist drill bits is the most common method to create cylindrical holes. With the constant development of additive manufacturing technologies and easier access to additive manufacturing equipment, it is now possible to design and fabricate solid tools suitable for various machining applications. Specially designed 3D printed drill bits seem more convenient for standard and nonstandard drilling operations than conventionally made tools.

- - The article discusses a study that explores how different edge radii of cutting tools impact the relative displacement between the tool and workpiece during longitudinal turning processes, specifically using X37CrMoV5-1 steel.
- - Researchers used a test stand to measure vibrations and relative displacements, discovering standard deviations ranging from 0.36 to 0.78 μm with various edge radii across different feed rates.
- - A key finding was that the smallest relative displacements occurred at a feed rate of 0.12 mm/rev for all tested inserts, leading to the development of a formula to forecast the Ra roughness parameter based on these results.
A Method to Determine the Minimum Chip Thickness during Longitudinal Turning.
Micromachines (Basel)
November 2020
Micromachining, which is used for various industrial purposes, requires the depth of cut and feed to be expressed in micrometers. Appropriate stock allowance and cutting conditions need to be selected to ensure that excess material is removed in the form of chips. To calculate the allowance, it is essential to take into account the tool nose radius, as this cutting parameter affects the minimum chip thickness.

- The article studies temperature data from an aluminum alloy during face milling using four cutting strategies, measuring temperatures with K-type thermocouples at six points.
- It uses numerical simulations through finite element and finite difference methods to analyze heat transfer in the cutting zone and compares these results with experimental data.
- The findings indicate that temperature distribution affects surface flatness at the ends of the workpiece, influenced by both the depth of cut and the chosen cutting strategy related to the material's thermophysical properties.
