Reduction of burr generation with solid lubricating sheet for drilling titanium alloy

Nihon Kikai Gakkai ronbunshu, 2015
This paper clarified the effects of solid lubricating sheet for reduction of burr generation and lowering of cutting temperature through examining of drilling in titanium alloy for aircraft. Titanium alloy is difficult to drilling. Moreover worker cannot

Research on Parameter Optimization of Micro-Milling Al7075 Based on Edge-Size-Effect

Micromachines, 2020
In the process of micro-milling, the appearance of the edge-size-effect of micro-milling tools cannot be ignored when the cutting parameters are smaller than the cutting edge arc radius (r0) of the micro-milling tool or close to it, and it could easily ...

Study on the Deburring of Intersecting Holes with Abrasive Flow Machining [PDF]

한국정밀공학회지, 2019
Intersecting holes deep inside a workpiece, are difficult to deburr because of poor accessibility. When holes are small and the intersecting angle (acute angle between hole axes) is less than 45o, difficulty is at its extreme.

Removal of Drilling-Milling Composite Burrs by Abrasive Flow [PDF]

한국정밀공학회지, 2019
When a workpiece contains complex burr edges from a combination of drilling and milling, conventional deburring tools such as wire brushes may not be effective in their removal.

Experimental analysis of wear and multi-shape burr loading during neurosurgical bone grinding

Journal of Materials Research and Technology, 2021
Amid bone grinding, a part of the hard tissue (i.e. bone) is usually removed to gain clearer operative excess to the tumours present beneath the bone. The tool wear and tool loading influence the thermal as well as mechanical conditions of surgery.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...
