The cutting behavior of cortical bone in different bone osten cutting angles and depths of cut [PDF]

, 2021
Abstract Cortical bones are semi-brittle and anisotropic, this brings the challenge to suppress vibration and avoid undesired fracture in precise cutting processes in surgeries. In this paper, we proposed a novel analytical model to represent cutting processes of cortical bones, and we used to evaluate cutting forces and fracture toughness, and

An Experimental Study on the Depth of Cut of Granite in Abrasive Waterjet Cutting

Materials and Manufacturing Processes, 2011
Many studies investigating the cutting performances of waterjets for several kinds of materials such as steel, brass, glass, or aluminium are available. However, there are few studies focused on the rock cutting in the literature. In the present study, therefore, it is aimed at investigating the cuttability of granite by abrasive waterjet.

DEPTHS OF CUT IDENTIFICATION IN 3-AXIS MILLING USING CUTTING FORCE SPECTRUM

MM Science Journal, 2021
Cutting forces analysis is one of the most important means of improving machining quality and productivity. In 3-axis milling, the frequency domain analysis of the cutting forces provides information which can be adopted for both predicting and monitoring the cutting process.

The Ratio of Feed to Depth of Cut in Metal Cutting

Journal of the Japan Society of Precision Engineering, 1962
When a metal is cut simultaniously by end and side cutting edges of a tool with the back rake angle i and side rake angle λ, the chip flows to a definite direction determined not only by the rake angles, but also by the ratio of feed to depth of cut.The optimum chip-flow direction of minimum energy can be controlled by choosing the ratio of feed to ...

Venetoclax‐Based Therapy as a Bridge to Hematopoietic Stem Cell Transplantation in Relapsed or Refractory Pediatric Acute Leukemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Relapsed and/or refractory (R/R) pediatric acute leukemia carries a dismal prognosis, largely driven by chemoresistance to conventional salvage therapy. The BH3‐mimetic venetoclax, combined with chemotherapy or hypomethylating agents, has demonstrated efficacy in small clinical trials.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
