Automation of Automotive Parts Trimming and Circular Machining Process

Machine tending is especially suitable for robotic automation due to its simple and repetitive nature. Loading and unloading parts in machinery such as CNC lathes and milling machines often lead to fatigue, errors, and potential safety risks. Robots perform these tasks with precision and consistency, thereby enhancing product reliability. Moreover, deploying robots in hazardous or challenging environments improves workplace safety, and their ability to operate continuously without breaks allows for 24-hour production. Among various automation processes, machine tending stands out as one of the most preferred options due to its high cost-effectiveness and quick return on investment. Boyoung Metal is a specialized manufacturer supplying key automotive components based on advanced metal processing technology and strict quality control.

Introduction

Automation of Automotive Parts Trimming and Circular Machining Process

The robotic trimming automation process is an application in the automotive component (DIFF CUP) production line, where a 6-axis industrial robot is used to automate the continuous trimming operation. Burrs on complex-shaped parts are removed using machine tending.

Key Feature

Key Advanced of HD Hyundai Robotics

  • Improved Productivity and Prevention of Industrial Accidents

    With robotic automation, tasks can be performed rapidly and consistently, resulting in a significant boost in overall productivity. In fact, Boyoung Metal was able to reduce the number of operators from four to two through robot automation, while simultaneously increasing production output.
    Additionally, the process of loading and unloading parts from machines involves contact with high-speed equipment and sharp machining tools, making it a hazardous task. Robotic systems greatly enhance worker safety in these environments. By integrating conveyor systems with robots, as seen at Boyoung Metal, human involvement is minimized, reducing operator interference and human error.

Solution

Continuous Trimming Process

To minimize cycle time (C/T), the process is designed for uninterrupted, continuous production, achieving a monthly output of approximately 100,000 units.

 

01

Simultaneous Loading and Unloading Gripper

The gripper allows the robot to simultaneously remove finished parts and load new components into the equipment in a single motion. This dual-function action significantly reduces unnecessary robot movement, shortens process time, and greatly enhances production efficiency. It is also effective in terms of space utilization, contributing to the construction of compact automated lines.

 

02

Component Loading via Conveyor System

The workforce previously required for this process was successfully reduced from four to two operators. Components are automatically transferred at regular intervals via the conveyor, allowing the robot to detect and accurately position them or perform trimming operations. This minimizes operator involvement, significantly reducing human error and interference during repetitive tasks.

In particular, issues such as quality discrepancies caused by varying skill levels among workers or safety risks from workflow collisions were common. However, with the conveyor-based automation system, these variables have been eliminated, leading to a more consistent and stable production environment. This improvement not only reduces manpower but also makes a meaningful contribution to overall product quality and operational safety.
