“…The difference between CNC machine tools and ordinary machine tools lies in the working sequence of NC machine tools: according to the requirements of part processing, CNC language is used to write processing sequences and parameter programs. After the program is analyzed and processed by the CNC device, the execution instructions are sent to the servo system to actuate the motion of the machine tool [1]. Programming controlled movement of the main spindle and worktable completes the processing that does not exist in ordinary machine tools.…”

This chapter mainly introduces production processing optimization, especially for machining processing optimization on CNC. The sensor collects the original vibration data in time domain and converts them to the main feature vector using signal processing technologies, such as fast Fourier transform (FFT), short-time Fourier transform (STFT), and wavelet packet in the 5G AI edge computing. Subsequently, the main feature will be sent for cloud computing using genetic programming, Space Vector Machine (SVM), etc. to obtain optimization results. The optimization parameters in this work include machining spindle rotation velocity, cutting speed, and cutting depth, while, the result is the optimized main spindle rotation speed range of CNC, which met machining roughness requirements. Finally, the relationship between vibration velocity and machining quality is further studied to optimize the three operational parameters.

“…The design of an automated cutting table is a multidisciplinary project that involves computing, electronic and electromechanical concepts, among other areas. In the country, some work has been done on the design of machine tools [1,2], such as lathes, milling machines and cutting tables, an example of them is the study carried out by the Universidad Pontificia Bolivariana of Medellín, where an XYZ Cartesian table was developed to study the kinematics, dynamics and control problems associated with automated industrial equipment [3]. These works, although interesting, have been limited to a functional and robust design, without going too deeply into the key aspects associated with the work of a machine tool.…”

This document describes the fundamental criteria in the design of a Cartesian table automated with three axes XYZ with an interchangeable head to work with plasma cutting and oxyfuel, as the selection of the processes implemented for its construction. For this the table splits into four fundamental parts; X axis, Y axis, Z axis and control system. It is begun by a conceptual design in which the basic dimensions of the table are defined and a counterfoil of selection of components is realized, then in a detailed design to determine the dimensions and exact characteristics of every component. Later, the systems and subsystems of the table, that generate significant effects on the structural elements, were validated by means of charges simulations. The elements selection was based on the esthetics, availability of materials and processes of manufacture of easy access on the market that were offering high quality to low cost. In order to conclude, with the detailed design in this document, it is possible to construct a table CNC with high precision and low cost.

“…In the case of machine tools and robots, a servo loop update time lower than 1 ms is required. 6,7 Several CNC systems are designed using sequential microprocessors or personal computer (PC)-based systems, and some using a combination of PC and digital signal processor (DSP) for implementing curve interpolation techniques such as curve interpolation and tracking control, 8 NURBS interpolation, 9 and off-line algorithm for the feed rate scheduling constrained by chord tolerance, acceleration, and jerk limitations. 10 In order to enhance the capabilities and performance of sequential controllers, several parallel architectures have been proposed.…”

Motion controllers are widely used in many mechatronic applications such as computer numerically controlled machine tools and robots. These applications demand the use of high performance controllers. Some desirable characteristics in motion controllers are coordinated multi-axis control, smooth movements, and advanced interpolation methods. An important manufacturing aspect involves the production of a workpiece in a free form or using the parametric surfaces in modern computer aided design/computer aided manufacturing systems. The use of parametric curves and surfaces has become standard due to their ability to represent objects having complex surfaces with less data. Another mandatory characteristic of motion controllers is the real-time operation. The contribution of the present work is the design and implementation of a hardware-software system for multi-axis motion control featuring non uniform rational Bsplines interpolation. Advantages over other reported works are the hardware implementation which allows the application to real computer numerically controlled machines; also the parallel processing permits the incorporation of additional modules to form an integral system without dependence on external devices. Two experiments were carried out in a retrofitted-to-computer numeric control milling machine in order to show the efficiency of the developed system.
