This report presents the comprehensive development and integration of a CNC machine, emphasizing both its mechanical and electronic subsystems. The mechanical subsystem includes detailed configurations. The electronic subsystem is driven by VHDL (VHSIC Hardware Description Language) programming, which provides precise control over hardware design and supports concurrent processes essential for real-time operations. The report delves into the advantages of using VHDL for FPGA (Field Programmable Gate Array) programming, highlighting its flexibility and efficiency. Detailed block diagrams and flowcharts illustrate the system’s overall functionality, showing the interaction between modules like the clock divider, shape selector, and multiplexer. Each shape module-square, triangle, diamond, and rectangle—was meticulously designed to manage specific geometric operations, showcasing the system’s versatility. The modular design approach adopted in this project enhances the system’s scalability and main-tainability, providing a robust framework for future enhancements. The integration of mechanical precision with advanced control logic underscores the complexity and innovation inherent in modern CNC technology. This report dives in the field of CNC machine development by offering a detailed methodology and practical insights into integrating mechanical and electronic subsystems.

FPGA based microstepping controller.
(Université M’hamed Bougara de Boumerdes : Institut de Genie Electrique et Electronique, 2023) Rahal, Chahira; Benzekri, A. (Supervisor)
This project describes the design, simulation and implementation of an FPGA-based microstepping driver to control a dual H-Bridge to properly commutate a bipolar perma- nent magnet stepper motor for precise-position tracking applications. The kernel of the driver is a microstepping mode algorithm implemented in two ROMs as look-up tables.This engine is used to generate the appropriate pulse width modulation (PWM) signals to control the current levels in the motor’s windings. Because the current patterns in the win- dings closely resemble sine waves with 90° phase shift, we used a sinusoidal (sine/cosine) approximations function to build the look-up table to drive the motor’s windings. The digital driver is developed with the Very high speed integrated circuit Hardware Descrip- tion Language (VHDL). The driver is synthesized using Quartus® II, the Intel®- FPGA software development suite tools, and targeted at an FPGA of the Cyclone-II family. Computer simulations are carried on Quartus II simulator. The results show the effec- tiveness and merit of this design process by testing several fractions of a full step (1/2,1/4 and 1/8). In addition, the real-time applicability of this driver is exemplifie do na permanent magnet bipolar stepper motor.
FPGA based VGA controller and arcade games
(2016) Lakhdari, Zineb; Elkhabazi, Hayet; Benzekri, A. (Supervisor)
This report describes the design and implementation of an FPGA-based VGA controller and arcade games. The hardware modules are developed in the Very High Speed Hardware Description Language (VHDL) and implemented onto the FPGA of the low-cost DE2 board. As a standard interface, Video Graphic Array VGA has been widely used. The system displays on the VGA monitor a menu which consists of two games (pong & breakout games), where the user is able to choose any one of them. The first game is a two player game, they are controlling paddles to punch a moving ball to the opponent's side. Whereas the second game is a one player game, in which he controls a moving paddle to bounce the ball trying to destroy all the bricks that are situated on the top of screen. During the course of this project we added some modifications such as the adjustment of the paddles and ball’s speed, yet the text generation like the score of players, the menu selection. The results show that the proposed algorithms give good performance with short processing time, low resource utilization, small power consumption and memory usage. Because the data can be sent directly to monitors, the design improve system reliability in real time and save hardware resource.
FPGA-Based artificial neural network driving a Stepper Motor
(2022) Oudjehan, Celina; Bennour, Khadidja; Benzekri, A. (Supervisor)
This report describes the design and implementation of an FPGA-based Artificial Neural Network (ANN) for character recognition. The ANN algorithm is fully developed using VHDL in the structural modelling style. It comprises of 16 nodes in the input layer, 32 in the hidden layer and 16 in the output layer. The processing of data is done in the IEEE single precision floating-point format. In order to train the ANN, a dataset of 4×4 matrices stored in a VHDL file is used to represent the 16 letters to be recognized: A, C, D, F, H, I, J, L, N, O, P, T, U, X, Y, Z that are selected based on the feasibility of their representation in such dimensions. The weights are randomly initialized with a 16-bit Galois LFSR that has a maximum period of 65535, which are stored in an on-board SRAM unit of 2MB storage capacity. The DE2-115 board hardware platform is utilized to synthesize the overall system with the Quartus II software version 13.0. The built-in LCD display serves as an interface for the user to input the desired pattern on the two 4×4 grids, as well as to show the output class of the recognition process. We added a stepper motor circuit to test the working of the ANN with “ON” and “OF” patterns.

Implementation of low cost three axis CNC machine with network control
(2016) Messaoudi, Adel; Belhocine, Billal; Benzekri, A. (Supervisor)
Increase in the rapid growth of Technology significantly increased the usage and utilization of Computer Numerical Control (CNC) systems in industries but at considerable expensive. The idea on fabrication of low cost CNC came forward to reduce the cost and complexity in CNC systems. This work discusses the design and implementation of low cost three dimensional CNC machine using off-the-shelf components. We built the mechanical system which contains three axis X, Y and Z where three stepper motors and their drivers were used to move it. A microcontroller was used to control the stepper motors after interpreting the streamed g-code received from USB/Serial port of the Raspberry Pi where it offers two ways of controlling the machine. The first one is local control (machine location) where a GUI application was developed using Python programming language. The second is a control via network where Raspberry Pi hosts the web application that was developed using Node.js and bootstrap framework. The prototype CNC works well and some designs and models were successfully and accurately produced.
