The average particle size of PEEK was reduced to 100 μm only after 5 cycles of pan‐milling and reached less than 50 μm after 50 cycles. DSC analysis showed that crystallinity of PEEK decreased with the pan‐milling cycles, agreed with WAXD data. The crystallinity of PEEK decreased from 46.2 to 39.9% of 50 pan‐milling cycles was offered.

Introduction Dynamic models can be used to predict the dynamic behavior of machine tools, structural elements and workpieces in machining simulations [1]. The dynamic properties of these components can be modeled based on damped harmonic oscillators, which can be characterized by the frequency response functions (FRFs) of a structure.

While more realistic aspects of your blocking will be informed by character behavior and psychology, you want to consider balancing this approach with moments that create aesthetically compelling stage pictures. Experiment with variations in spacing and composition.

In this study, an attempt is made to use the cutting tool's self-excited vibration during a cutting beneficially to generate microtextures. This approach is named as "controlled chatter machining (CCM)." Modal analysis is first performed to study the dynamic behavior of the cutting tool. Turning processes are then conducted by varying the ...

Dynamic light scattering (DLS) is widely used and preferred technique in characterization of nanoparticles on a simple solvent or biological environment [14, 16–18]. Non-invasive and fast measurement when sample is in its native colloidal state and good statistical significance of the result are the strengths of DLS [ 19 ].

Nickel-based alloys provide high corrosion resistance and high-temperature strength but these alloys possess poor machinability. Hastelloy-X is a nickel based alloy that has been used for high temperature use. There are many studies about finite element modeling of aerospace alloys but studies in literature with Hastelloy-X are limited. In the present work, machining characteristics of ...

12%Through an experimental modal characterization, significant variability of modal parameters is observed at the tool tip and impacts the stability of machining. The results show that an adjustment of the cutting conditions must accompany the change of robot posture during machining to ensure stability. Download to read the full article text.

The Silent Generation: Characteristics and History. The term "Silent Generation" was first documented in a 1951 Time magazine article, which claimed that the most startling fact about this generation was its silence: "By comparison with the Flaming Youth of their fathers and mothers, today's younger generation is a still, small flame.".

The particle analyzer CAMSIZER P4 uses the principle of dynamic image analysis (ISO 13322-2). The sample is transported to the measurement field via a vibratory feeder where the particles drop between a planar light source and two CCD cameras. The projected particle shadows are recorded at a rate of more than 60 images per second and analyzed.

Particle size analyzers play an important role during process development and quality control of particle systems in order to develop efficient processes and achieve high final product quality. Traditionally, sampling and offline particle size analyzers (laser diffraction, dynamic light scattering, sedimentation or sieve rest analysis) were ...

the information is inherently dynamic. Models and displays based on static information (such as histograms of pages requested) will not fully capture the dynamic nature of the underlying web-surfing behavior. Thus, we investigate relatively simple Markov models to represent dynamic behavior. An important point in this context is that these dynamic
