Inconel 718 is a typical hard-to-machine material that requires thermally enhanced machining technology such as laser-assisted milling. Based upon finite element analysis, this study simulates the forces in the laser-assisted milling process of Inconel 718 considering the effects of grain growth due to c0 and c00 phases. The c0 0 phase is unstable and becomes the d phase, which is likely to pre...

Most red lentil produced worldwide is consumed in dehulled form, and post-harvest milling and splitting qualities are major concerns in the secondary processing industry. Lentil producers in northern temperate regions usually apply pre-harvest desiccants as harvest aids to accelerate the lentil crop drying process and facilitate harvesting operations. This paper reports on field studies conduct...

This paper contains data and supporting information of and complementary to the research article entitled "Effect of jar shape on high-energy planetary ball milling efficiency: simulations and experiments" (Broseghini et al.,) [1]. Calcium fluoride (CaF2) was ground using two jars of different shape (cylindrical and half-moon) installed on a planetary ball-mill, exploring different operating co...

An autonomous machine tool has been developed to solve fundamental issues with the current command method using NC programs, and some key technologies for its realization have been devised. In the process planning system, various process plans are prepared, and the appropriate process plan can be selected to achieve flexible machining operations. Digital Copy Milling, digitizing the principle o...

We evaluated the effects of conventional hand rasping and robotic milling on the clinical and radiographic results of cementless total hip arthroplasty, with the same computed tomography (CT)-based 3-dimensional preoperative planning using a ROBODOC workstation (Integrated Surgical Systems, Davis, Calif). The robotic milling group consisted of 78 hips, and the hand-rasping group 78 hips. The ra...

Three experiments were conducted to determine the maximal amount of concentrate and forage that could be replaced with a new wet corn milling product. The corn milling product contained 23.1% crude protein, 9.9% ruminally undegradable protein, 13.7% acid detergent fiber, 40.3% neutral detergent fiber, and 2.6% ether extract (% of dry matter; DM). In experiment 1, 16 Holstein cows were assigned ...

Mechanical cleavage by Scotch tape was the first method to produce graphene and is still widely used in laboratories. However, a critical problem of this method is the extremely low yield. We have tailored ball milling conditions to produce gentle shear forces that produce high quality boron nitride (BN) nanosheets in high yield and efficiency. The in-plane structure of the BN nanosheets has no...

In this paper, an effective algorithm based on improved time-domain averaging is proposed to detect tool flute breakage during end milling using feed-motor current signatures. The algorithm proposed is demonstrated to be effective in detecting tool flute breakage in real time through a series of milling experiments, and is also demonstrated to be insensitive to the effects for transients, such ...

In order to machine micro structured dies and molds made of ceramics, micro milling tools made of poly-crystalline diamond (PCD) are developed. Many cutting edges are ground with diamond wheels. Tool wears of the PCD milling tool are evaluated by cutting spherical molds made of binder-less tungsten carbide and structured surfaces are machined for trial. From the experiments, it is clarified tha...

This paper presents a new method of computing constant scallop height tool paths in 5-axis milling. Indeed, usual iso-scallop tool path computation methods in 3-axis or 5-axis milling generate tool path self-intersections, which prevent from reaching the required quality and productivity. The proposed approach consists in following parallel planes in 5-axis milling to avoid self-intersection of...
