Computer numerical control (CNC) controller is the termination organiser, which is located at the end of the manufacturing process chain. The CNC controller is composed of two modules: software and hardware. The software module of the lontroller is known as interpreter that translates Intemational Standards Organization (lSO) data interface model instructions to the hardware parts of the contro...

In this paper, a method of reducing the tracking error in CNC machining is proposed. The structured neural network is used to approximate the discontinuous friction in CNC machining, which has jump points and uncertainties. With the estimated nonlinear friction function, the reshaped trajectory can be computed from the desired one by solving a second order ODE such that when the reshaped trajec...

The aim of the paper is to present computer software which analyse a geometric design of product and determine which part of product will be done with CNC milling and which part will be done with additive technology. Subsequently it split the CAD model of product on two or more part and save part for CNC milling in format which is used for making CNC code and save part for additive manufacturin...

In this study, we have a research of the methods of the special post processing program developing of Five-axis CNC machine DMC 70ev. On the basis of analysis about the characteristics of MILLPLUS IT V530 CNumerical control system, special post processor applied to five-axis CNC machining mode based on IMSPost was developed. Special post processing program developed was proved its accuracy and ...

The mechanical properties of rodlike cellulose nanocrystals (CNCs) suggest great potential as bioderived reinforcement in (nano)composites. Poly(vinyl alcohol) (PVOH) is a useful industrial material and very compatible with CNC chemistry. High performance CNC/PVOH composite fibers were produced coaxial coagulation spinning, followed by hot-drawing. We showed that CNCs increase the alignment and...

Computer numerically controlled (CNC) machines have evolved to adapt to increasing technological and industrial requirements. To cover these needs, new generation machines have to perform monitoring strategies by incorporating multiple sensors. Since in most of applications the online Processing of the variables is essential, the use of smart sensors is necessary. The contribution of this work ...

With the increasing demands of high surface irregularities and machining of composites, conventional machining processes are now being replaced by high speed Computer Numerical Control (CNC) machines. In this paper aluminium silicate made from alloying aluminium and silicon oxide made from rice husk are used. The machining of the alloy on CNC machine is carried out. In addition to speed, feed a...

Intel Concurrent Collections (CnC) is a parallel programming model in which a network of steps (functions) communicate through message-passing as well as a limited form of shared memory. This paper describes a new implementation of CnC for Haskell. Compared to existing parallel programming models for Haskell, CnC occupies a useful point in the design space: pure and deterministic like Strategie...

AHadamard matrix is said to be completely non-cyclic (CNC) if there are no two rows (or two columns) that are shift equivalent in its reduced form. In this paper, we present three new constructions of CNC Hadamard matrices. We give a primary construction using a flipping operation on the submatrices of the reduced form of a Hadamard matrix. We show that, up to some restrictions, the Kronecker p...
