The flexible MH80 material handling robot from the Motoman Robotics division of Yaskawa America is suitable for a variety of applications, including dispensing and material cutting, in addition to material handling. The robot’s long reach enables it to handle large parts. Fast axial speeds and acceleration are designed to reduce cycle times and increase production output. Internally routed cables and hoses also maximize system reliability, minimize interference and facilitate programming, the company says.
The robot features an 80-kg (176.4-lb) payload, 2,061-mm (81.1") horizontal reach, 3,578-mm (140.9") vertical reach and ±0.07-mm (0.003") repeatability. Its wide work envelope and small interference zones enable it to be placed in close proximity to workpieces and equipment, reducing floorspace requirements. The robot is also equipped with brakes on all axes and can be floor, wall or ceiling mounted.
A DX100 controller with multiple-robot-control technology is designed to handle multiple tasks and control as many as eight robots (72 axes), I/O devices and communication protocols. The controller is designed with increased processing speeds for smoother interpolation, advanced robot arm motion, built-in collision avoidance, quicker I/O response and accelerated Ethernet communication.
Expanding capacity into the unattended hours calls for counterintuitive new ways of thinking about the work.
Programming a robot with the same CAM software used for a multi-axis machine tool makes it unnecessary to “teach” the robot by jogging it manually from point to point and recording these point-to-point moves as the robot’s motion commands. Robotmaster is a software package that provides this CAD/CAM-based, off-line programming for robots. It runs fully integrated inside Mastercam CAM software for CNC machine tools.
Custom engineered workholding fixtures are key to the effectiveness of an unusual Automated Production System (APS) recently installed at Kurt Manufacturing. It helps that one of this company’s specialties is custom engineered workholding fixtures.
