About The Project

The project serves as the focal point of the master's thesis in mechanical engineering. The primary goal of this project is to develop a compact incremental forming machine. The machine will be electric, ensuring a silent operation and compact size to facilitate coexistence with 3D printers. To effectively cover all aspects of machine construction, the project has been divided into three key areas: machine structure design, mechanical project, and automation project.

Machine structure design

Base requirements:

Architecture:

The study of possible configurations is demonstrated in issues #1 to #4. After the analysis it is concluded that the best configuration is case 1.1.1.. To choose the best configuration, the lowest possible torque was taken into account.

• 2 arms in parallel (delta 2)
• Distance between motors: 50 mm
• L1 = 120;
• L2 = 150;
• y _ work area = -320 mm
• Maximum torque: 665 Nm

Direct and indirect kinematic analysis:

The direct and indirect kinematics are represented in the issue #16 and in chapter 3.3 of the thesis document.

Mechanical project

Mechanical projects steps:

• Arm design
• Support system for the forming punch
• Selection and sizing of the motor-reducer set
• Selection and sizing of the linear motor-autorator set
• Structural configuration

Simulation:

Two types of simulations were carried out using Solidworks: with motion analysis and static . Both analyzes are described in section 4.6.1 and 4.6.2, respectively, in the thesis document. Some steps for carrying out the simulations are described in the issue #5.

Automation project

Automation projects steps:

• Wiring Diagram and Main Components
• Power Circuit
• Controller (Controllino MEGA)
• Drive (CL86T Closed-loop Stepper Drive)
• Security Elements
• Switchboard
• Motion Control: Implementation of Kinematics, Determination of the Number of Pulses, Incremental Positioning
• Graphic User Interface: Manual Mode, Automatic Mode, Information Page

All steps of the automation project as well as its implementation are described in chapters 5 and 6.2 of the thesis document. It is also possible to find some information in the issues #15, #17 - #20, #22 e #23. The developed code can be found here. The controller program was carried out in the Arduino IDE platform and the code for the GUI in MATLAB.
