“…Stainless steel wire wear has been a concern as severe wear can cause wire breakage. Schwinde et al [18] found the wear of wire only occurs at bottom of the sawing groove, where the material removal takes place mostly. This indicates that the wire is not rotating around its longitudinal axis during slicing.…”

In topography detection procedures for diamond wire, precision motion control is one of the key preconditions; the motion control unit of detection needs both micron resolutions and centimeter strokes. In this paper, a linear motor with four sets of multilayer piezoelectric actuators was developed to achieve an actuator with high resolution and a large stroke. The stroke depended on the guideways of the system, which mar enlarged the stroke of a single multilayer piezoelectric actuator. The mechanism of differential actuation was analyzed by dividing an operation cycle into several states. A symmetrically arranged four-foot design was proposed, and a corresponding excitation method was devised. A prototype was fabricated to conduct a proof-of-concept operation test. Experimental results validated the feasibility of the prototype with a 10 mm stroke. The speed of the prototype increased when the amplitudes of driving voltage signals increased from 30 V to 100 V. Within the frequency range of 1 Hz to 120 Hz, the speed increased initially then decreased with driving frequency, the maximum of which was at 100 Hz. With an excitation voltage signal of 100 V and 100 Hz, the speed reached a maximum of 740 µm/s. With an excitation voltage signal of 30 V and 120 Hz, the resolution of the prototype reached 0.26 µm. The prototype satisfies precision motion control of topography detection for diamond wire. This work also provides an option for automatic systems that require high resolutions and large strokes.

“…High power and large power wire saw as one of raw stone mining equipment development direction, the main motor plate stress concentration and complex, high strength, stiffness requirements, is the key-module system, has a great influence on the whole machine function and reliability, the need for reliability and optimization design. Osman et al [2][3][4] studied the concrete ways on increasing the performance of chain saw machines for mechanical excavation of marbles and natural stones. Cao Hanqing et al [5] by using finite element analysis developed a optimization design of the structure and fatigue analysis for improvement of the safety and reliability of the transmission shaft.…”

The main motor supporting plate is the connector of super power wire sawing machine between main motion mechanism and the main motor with force concentrated and complex forces, high level of requirements in stress and rigidity, having a great influence on the reliability of the total machine. Based on the physics and mechanics modeling, the current study is carried out on the mechanics and modal analyses. The theory of optimization is adopted, on the premise of meeting the requirements of reliability under the condition of lightness as the goal with the strength and stiffness constraints, basic size of the plate as decision variables, using the penalty function interior point method, for analysis and design optimization. The actual application shows that the design not only guarantees the reliability of the overall working condition of the superpower rope saw, but also reduces the quality of the plate by 9.5%.
