These advantages include a potential for good control and adjustment of input energy, high uniformity of energy distribution over the beam cross-section area as large as tens of square centimeters, and high efficiency factor for low reflectivity factor surfaces.
Microhardness tester was used for mechanical strength characterization.
One can see the top (2-3) mm thickness layer, transition 5 mm thickness layer and heat-affected layer separated by a chain of microvoids from the base metal.
The underlying layer of hard metal carbide 30-40mm microcrystallites is developed within the heat affected zone after pulse electron beam treatment of the hard metal.

Design accuracy is assessed according to strength and deformation properties of wires a rope is made of and a rope cross-section construction is taken in account as well.
The paper presents models of ropes equally loaded which eliminates the most unfavorable factors affecting their life cycle.
The strands in the rope together with the tensile modulus in the tension of wires and Poisson's steel ratio [7] for wire ropes used are the parameters which should be assigned to the put to sleep effect of the rope strands and the rope itself including lubrication reducing the friction between the wires when the rope is working [8].There is a number of factors affecting the service life of wire ropes but one of the fundamental ones is load of a rope, strands and wires.
The bindings in the nodes 1-6 detract two degrees of freedom, one of the binding forces is affecting the tangent of the circle written by the strand.

In this paper, based on the structure analysis of feeding system in a certain type of silicon ultra-precision grinding machine, the rigid body coupling virtual prototype model of the feeding system is established using ADAMS, the factors which influencing the stick-slip is analyzed deeply via the dynamic simulation of the virtual prototype.
Introduction As a core part of the silicon ultra-precision grinding machine, the performance indicators of the feed system is one of the key factors which influence affects the machining precision of the silicon wafer.
By combining the function of HyperMesh, ANSYS and ADAMS, the elastic properties of the object can be simulated, so the more practical stick-slip simulation analysis can be achieved.
In order to effectively reduce the occurrence of stick-slip, the factors which influencing the stick-slip of the feeding system in silicon ultra-precision grinding machine is analyzed deeply.
