Process Overview

This machine tending automation solution performs continuous machining processes by integrating three Yaskawa robots with six Doosan machine tools.

In the first machining process, one robot operates two machine tools. Once the first machining is completed and the workpiece is transferred to the downstream process, the other two robots interface with four machine tools to perform the second machining process.

This configuration enables high productivity through continuous machining of a single product.

Components

Robot	Yaskawa MH24 x 3 units 6-axis articulated robot Payload: 24 kg Working range: 1,730 mm Weight: 250 kg Repeatability: ±0.08 mm
Peripherals	Tool: (double) pneumatic gripper x 3 sets Equipment: Doosan Machining Center PUMA series x 6 units Peripheral devices: robot mounting base x 3 units Infeed/outfeed inline conveyor x 2 units Workpiece (picking) position correction jig x 3 units Small press-fit station x 2 units Safety fence

Workflow

STEP 1.	Load 1st machining workpiece
STEP 2.	Load completed part onto conveyor for 2nd machining
STEP 3.	Pick 2nd machining workpiece
STEP 4.	Adjust gripping position to match machining position (position correction jig)
STEP 5.	Load 2nd machining workpiece
STEP 6.	Insert finished part into small press-fit station
STEP 7.	Load press-fit completed product onto discharge conveyor

Recommended Use Cases

Automotive Parts Protective Film Application and Inspection using DENSO Robot

Process Overview This inspection automation solution uses the DENSO VM60B1 robot to automate quality inspection and protective film application for automotive parts by performing taping and inspection processes through robotic wrapping. By switching between three tools, the system performs gate cutting, protective film application, and inspection in a single integrated workflow, minimizing management points and improving overall productivity.

Wheel Machining Support Automation with ABB IRB 6640

Process Overview This solution automates machine tending for machining high-payload automotive wheels using an ABB IRB 6640 robot. Since automotive wheels are heavy workpieces (over 8 kg) that are difficult and physically demanding for operators to handle, robot automation supports two machining centers at the same time, improving productivity and operator satisfaction.

Automotive Button Switch Testing Automation with Dual EPSON C4 Robots

Process Overview This solution automates button click testing for assembled automotive switch boxes using two Epson C4 robots. Fixed-position tests are performed using dedicated equipment, while model-dependent variable positions are handled by articulated robots, enabling short takt time and flexible operation.
