An end milling process is widely used in fabrication of complex contours and shape parts at high spindle speeds. Many researchers try to investigate one of important aspect, which come across during machining is the self exited chatter vibration which causes severe damage of the tool and quality of the machined surface. The present work is focused on the Magneto-Rheological Damping effect on st...

rapeseed cultivation in iran is growing rapidly while this product has been facing specific problems. every year a significant portion of edible oil is imported to the country from other countries. despite this deficit, a great amount of canola is being lost every year. therefore, in compliance with technical points, adding a suitable platform to the exisiting machineries may reduce the losses....

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...

Real time tool condition monitoring has great significance in modern manufacturing processes. In order to prevent possible damages to the workpiece or the machine tool, reliable monitoring techniques are required to provide fast response to the unexpected tool failure. Milling is one of the most fundamental machining operations. During the milling process, the current of feed motor is weakly re...

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 ...
