This automation solution utilizes the Doosan M1509 collaborative robot to support metal machining operations in a Machining Center (MCT). The project was designed to improve production efficiency, reduce defect rates, and enhance operational workflow by automating simple, repetitive tasks.

In the previous process, workers had to stand by the equipment constantly to manually load each workpiece. By delegating the loading and unloading tasks to the robot, operators can now manage and run multiple machines simultaneously. Furthermore, by implementing Gun Solution's technology, the robot can perform tasks in the same manner as a human operator even on older legacy machine tools, effectively reducing costs associated with separate hardware interfaces.

Components

Robot	Robot: Doosan M1509 (M-Series) Type: 6-axis articulated collaborative robot with 6 high-performance torque sensors Payload: 15kg (Note: Standard M1509 is 15kg, though user text mentioned 10kg) Reach: 1,300mm (Extended reach for deep machine access) Weight: 33kg Repeatability: ±0.05mm

Workflow

STEP 1.	Load raw materials into the pallet.
STEP 2.	Robot picks up the raw material.
STEP 3.	Load the material into the jig inside the Machining Center (MCT).
STEP 4.	Secure the material (Activate hydraulic switch).
STEP 5.	Close the MCT door.
STEP 6.	Push the "Start" switch.
STEP 7.	Machining process begins.
STEP 8.	Clean the part via air-blowing.
STEP 9.	Pick up the finished product.
STEP 10.	Unload the part back to its original position on the pallet.
STEP 11.	Clean the jig inside the MCT for the next cycle.

Features

Maximized Flexibility & Compact Installation through Collaboration

Human-Robot Synergy: Efficiency is boosted by having humans manage the overall workflow while the robot performs continuous, repetitive tasks.
Space-Efficient: Utilizes compact collaborative robots (cobots) to minimize the footprint required for installation, avoiding floor space congestion.
Enhanced Safety: Prevents workplace accidents by implementing high-safety cobots designed to work alongside human operators.

User-Friendly Robot Teaching

Legacy Machine Compatibility: Robots can be taught to operate exactly like a human, eliminating the need for expensive hardware interfaces even on older machine tools.
Direct Teaching: Supports intuitive "Direct Teaching," allowing users to manually move the robot arm to set positions.
Compliance Control: Uses torque sensors for compliance control, enabling the robot to perform delicate tasks like pressing a part firmly into a chuck.
Rapid Changeover: Even when product models change, additional teaching can be completed in under 10 minutes.

Work Safety & Quality Assurance

High-Sensitivity Collision Detection: Equipped with 6-axis torque sensors (0.2Nm resolution) that detect sensitive collisions from any direction to trigger an immediate emergency stop.
Soft Response Logic: Applies compliance control logic that reacts smoothly to external forces during picking and unloading, minimizing impact and protecting the product.
Heavy-Duty Performance: Utilizing a 15kg high-payload cobot allows for the automation of heavy-duty tasks that were previously difficult for standard collaborative robots.

Results

Key Benefits	Increased operational efficiency by allowing existing workers to take on additional high-value tasks.
Client Feedback	Most of our products have long machining cycles, which meant workers were wasting time just standing by the machines. Now, the robot handles the machining process while the operator only needs to swap out pallets periodically. This shift has drastically increased our overall work efficiency.

Recommended Use Cases

Bin Picking Automation using UR5e & 3D Vision

This solution was used to develop a bin picking workstation for ActiNav, Universal Robots' autonomous motion solution. ActiNav is a comprehensive system capable of vision inspection, collision avoidance, and real-time robot motion control. In collaboration with Vention, Universal Robots conducted research to improve the efficiency of bin picking based on workpiece height, picking angles, and the distance between the robot and parts. Vention developed a specialized workstation that allows for easy adjustment of these critical factors. Through testing the time and accuracy of picking 100 workpieces, the team successfully developed a workstation that reduced operation time by 40%.

UR10 and OnRobot 3FG15 Gripper for Machine Tending

This application case demonstrates a CNC lathe machine-tending demonstration process utilizing the Universal Robots UR10 and the OnRobot 3FG15 gripper. By leveraging a 3-finger gripper with a wide stroke, the system can be optimized for CNC lathe machining across a variety of product sizes, ensuring stable and centered handling of cylindrical workpieces.

Modular Assembly Line using UR5e & Vention Range Extender

This solution features a modular assembly line developed using Vention's modular workstations, designed for easy integration into existing production processes and flexible reconfiguration. The system allows for the seamless rearrangement of peripheral workstations around a central assembly hub. By combining Vention's belt-actuator-driven Range Extender with a collaborative robot, the line successfully automates part picking and assembly, utilizing a circulating pallet system for efficient material infeed and outfeed.
