Cutting forces are small, and in many cases insignificant, compared with noise during the micro-machining of many non-metals. The Neural-Network-based Periodic Tool Inspector (NPTI) is introduced to evaluate tool condition periodically on a test piece during the machining of non-metal workpieces. The cutting forces are measured when a slot is being cut on the test piece and the neural network e...

A novel method for fabricating an adhesive resistance surface is presented. Sandblasting and electrochemical machining were introduced to prepare micro-nano structures on the sample surface. Then, the prepared sample was immersed in a tridecafluoroctyltriethoxysilane ethanol solvent. The surface of the aluminum alloy sample roughened and covered with low-surface-energy chemical groups was exami...

One of the major tasks in a Molecular Dynamics (MD) simulation is the selection of adequate potential functions, and if the potentials don’t model the behaviour of the atoms correctly, the results produced from the simulation would be useless. Three popular potentials namely; EmbeddedAtom Potential (EAM), Morse and the Lennand-Jones, were employed to model copper workpiece and diamond tool in n...

The machining characteristics of the nanolithographic process were studied using atomic force microscopy. Nano-oxidation experiments were conducted to investigate the influence that the different experimental parameters had on height, width and the growth rate of the nanowires and nanodots as well as upon the machining efficiency. The experimental parameters included; the applied voltage, humid...

We present experimental and theoretical results to describe and explain processing outcomes when producing nanochannels that are a few times wider than the atomic force microscope (AFM) probe using an AFM. This is achieved when AFM tip-based machining is performed with reciprocating motion of the tip of the AFM probe. In this case, different feed directions with respect to the orientation of th...

5-axis machining operations bring new challenges for predicting cutting forces. Complex tool workpiece engagements and tool orientations make it difficult to adapt 3-axis process models for 5-axis operations. A new model is developed to predict cutting forces with arbitrary tool/workpiece engagement and tool feed direction. A discretization approach is used, in which the tool is composed of mul...

The subject matter of the above paper presents part research carried out as robotization manufacturing processes aircraft engine components. concerns robotic deburring V2500 diffuser’s sharp edges. diffuser is a precision casting characterized by slight variation in geometry workpiece depending on accuracy molds and phenomenon shrinkage during solidification. Due to small degree thus low cuttin...
