As we all know, the traditional material removal work is done manually, the cost is high, the efficiency is low, the accuracy of the parts is greatly affected by the manual, and the safety of workers is not effectively guaranteed, so what can be done to effectively solve these problems?
Today, I will take you to understand how robots replace human labor to solve this problem, let's look down together-
Material removal has become typical in a variety of industries in recent years, ranging from very light finishing to heavy gate removal. Some processes are relatively simple, while others require multiple tools and techniques to achieve the desired results. Material removal on the surface of a workpiece such as round, curved or irregular workpieces creates a number of process challenges that require secondary processing. Traditional material removal methods rely on skilled and experienced manual labor, which can lead to inconsistent quality and safety hazards. The only way to reduce costs, cycle times, and labor safety is through automation solutions, and let's take a look at how it can be automated.
Problems with material removal of complex shapes:
1. The shape of the workpiece is complex
2. It needs to be done by someone with skill and experience
3. It will cause technological challenges for secondary processing
4. High labor cost and potential safety hazards
Solutions from the Robotics Institute at Carnegie Mellon University
With the widespread use of robotic material removal processes in various industries, engineers at Carnegie Mellon University's Robotics Institute, with funding from the Advanced Manufacturing Robotics Institute (ARM), have found a way to solve two challenging material removal operations in one solution instead of manual labor. The team members were technical experts from Siemens and application engineers at Yaskawa, who worked together to develop the system, which automates the removal of welds in the tube.
The team designed a fully automated, active compliance system that automatically locates, measures, and removes welds inside pipes and verifies process completion. The system includes vision technology and force sensing technology, the vision system first identifies the weld for positioning, and then utilizes ATI's six-dimensional force/torque sensor to feed the force and torque data back to the robot in real time to enable the Yaskawa robotic arm to measure the weld bead and react to the weld bead, determine the correct pressure to be applied, and then remove the weld bead with a material removal tool. Finally, the system analyzer verifies that the work done meets the requirements.
The role of a six-dimensional force/torque sensor
ATI's six-dimensional force/torque sensors play a pivotal role in this application. It provides a comprehensive picture of the force and torque load required for data analysis, ATI's sensors can stably output the industry's highest resolution and accuracy of force and torque data, can detect and evaluate the grinding weld in real time, adjust the cutting force in time, realize the active compliance of the tool on the surface of the workpiece, and enable the robot to maintain a constant force on the workpiece. This ensures consistent surface finish and optimal cycle times, helping manufacturers reduce costs and increase productivity.
1. Real-time collection and transmission of force and torque data
2. Stable output of the industry's highest resolution and accuracy of force and torque values
3. A variety of ranges, a variety of communication systems, suitable for most robot controllers
For industrial manufacturers, the combination of Yaskawa's robots, ATI's six-axis force/torque sensors, and modeling software can effectively measure and remove welds from internal curves. This grinding system greatly reduces safety hazards, shortens process time, and improves overall process quality. Integrated floatability is an innovation that automates more precise material removal. Compensatory compliance can be either passive or active, allowing the robot to adjust in real-time in response to changes in the surface of the workpiece using tools. The Active Compliance system simplifies programming and safely and efficiently executes the challenges of heavy material removal and irregularly shaped workpieces, and has a growth space where projects like this hit the core mission of the Advanced Manufacturing Robotics Institute (ARM) to enhance manufacturing through innovation.
