in this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. the results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge. the...

A Numerically-Controlled (NC) machine typically consists of a worktable and a spindle (or cutter) with several axes of freedom for positioning the tool. In this paper, we restrict our attention to machines having only translational freedom. We focus on 2D milling, which can only cut out planar objects, and 2 1 2D milling where only two of the axes are continuous-path controlled and the third ax...

Abstract. This article establishes a system of anti-bud injury in sugarcane cutting based on computer vision using MATLAB software as a development platform. The seedcane cutter box cuts twice each turn. Match the accurate shutter trigger time interval according to the rotation speed of the cutter , the transportation speed of sugarcane, in order to make the position of collected image of the t...

Free-form surfaces are widely used in CAD systems to describe the part surface. Today, the most advanced machining of free from surfaces is done in five-axis machining using a flat end mill cutter. However, five-axis machining requires complex algorithms for gouging avoidance, collision detection and powerful computer-aided manufacturing (CAM) systems to support various operations. An accurate ...

In this paper, to simulate mechanical stress on the cutter bar of the harvesting combine during cutting of wheat stems, first, shearing strength of the stems was measured for various moisture content levels and cutting heights. After that the cutter bar of combine was simulated by Abaqus with the specified conditions. The results of the simulation showed that with increase in moisture content o...

The Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) is a relatively simple and inexpensive method for genotyping single nucleotide polymorphisms (SNPs). It requires minimal investment in instrumentation. Here, we describe a web application, 'SNP Cutter,' which designs PCR-RFLP assays on a batch of SNPs from the human genome. NCBI dbSNP rs IDs or formatted SNPs are ...

The purpose of this study is mainly to develop an information and communication technology (ICT)-based intelligent dimension inspection and tool wear compensation method for precision tuning. With the use of vibration signal processing/characteristics analysis technology combined with ICT, statistical analysis, and diagnosis algorithms, the method can be used to proceed with an on-line dimensio...

This paper studies optimization of tool path planning in 5-axis flank milling of ruled surfaces using advanced Particle Swarm Optimization (PSO) methods with machining error as an objective. We enlarge the solution space in the optimization by relaxing the constraint imposed by previous studies that the cutter must make contact with the boundary curves. Advanced Particle Swarm Optimization (APS...
