All these factors cause morphological and chemical changes to the wood surface during ageing [1,2].
Wood surface treatment always affects wood surface morphology.
Results and Discussion The properties of the wood surface treated with dry ice were compared with the original wood surface and with the plane milled wood surface.
The way of wood surface treatment and the anatomical direction were found as factors substantially influencing the wood surface roughness.

Coke then acquires semiconductor properties.
The pre-exponential factor characterizes the properties of the original coal, including its caking ability, the content of mineral impurities, and their ability to form free current carriers (electrons or holes).
The following tasks were required to achieve this goal: · Critically analyze modern methods that characterize the metallurgical properties of coke and factors that affect the value of SER
The implementation of the experiment allows for separately determining the influence of different factors (stickiness of the initial coal, quantity and composition of its mineral part, final coking temperature) on the specific electrical resistance of the obtained coke.
Specific electrical resistance is an important characteristic of coke, which is closely related to its readiness and the overall set of metallurgical properties. 2.

The thermal behavior of epoxy systems depends on a number of factors such as components used, mixing, curing conditions, and treatment of post-cure.
The results, sometimes divergent, for the thermomechanical properties of nanocomposites, are due to the fact that these properties are affected not only by the structure of nanocomposite, but by many other factors, such as the crosslinking density, charge-matrix adhesion and reaction kinetics and the method of determination [8].
Characterization and Properties Dynamic mechanical properties of samples were measured with a TA Q800 dynamical mechanical analyzer (DMA) in fixed frequency mode at 1 Hz with 15 μm oscillation amplitude, and from 30 to 180 °C at 5°C/min loaded under single cantilever mode.

Introduction 30Cr3SiNiMoVA (30Cr3) as a typical ultra-high-strength steel has obtained an increasing demand in aerospace and aviation industries due to its superior properties, such as high strength, strong corrosion resistance, high hardness, etc.
The relevant researches have shown that rounded cutting edge has been a primary factor influencing precision machining process.
H13 (52HRC) mold steel with the size of 2mm×2mm is chosen as the workpiece in the simulation since it has similar chemical composition and mechanical properties with 30Cr3.
A single factor methodology is employed in the FE simulation with rounded cutting edge radius as the variable.
