Introduction Grinding is a widely employed finishing process for different materials.
Moreover, some other researchers made grinding wheels intermingled with lubricant materials to reduce the heat generated at the grinding zone. [6-10].
Titanium alloy is one of the typical difficult-to-machine materials.

The results suggest a new design of microwave absorbers based on electromagnetic wave absorbing materials.
In this study, the Nd-Fe-B nanocomposites was chosen as electromagnetic wave-absorbing materials.
These nanocomposite materials were prepared by melt-spinning and subsequent annealing.

Based on the material constitutive and mechanism at ultra-low temperature, the numerical simulations are implemented and component test is expanded by using DIANA software environment.
The equipment used in the bending tests at low temperature for beams are the same as those for concrete material.

There is little data available in the literature describing the effect of FDM-printing technology on the properties of the resulting products and they relate to a relatively narrow range of polymeric materials, namely polylactide (PLA), acrylonitrile butadiene styrene (ABS) and polyetherimide (PEI) with the commercial name ULTEM 9085.
And the composite material with more viscosity than pure PPSF can’t provide enough adhesion in the small contact spot which leads to the properties reduction.
