Problems In Robot Automation Machining
Dec 01, 2017

1. Information Exchange Issues

Robot as a robot automated machining system member, could not exist independently.

Robot automation system hardware machining robot and machining robot-centered auxiliary robot group, including tool changers, loading and unloading robots, measuring robots, etc., as well as centralized control of the robot group of the host computer. There are many information exchange problems between robots, robots and computers, processing systems and management systems.

2. Stiffness and accuracy problems

The design and manufacture of key components are important to the machine's performance. The development of traditional machine tool structures has matured. Some important components have been designed and manufactured well. For example, large-stroke linear guides, multi-degree-of-freedom CNC turntables and multi-degree-of-freedom spindle heads are all available. Now high-precision CNC machine tools have been able to carry out high-precision machining operations.

Machining robots and general handling, grasping robots, its function and the same machine, is used for mechanical cutting, and its principle of motion should also consider the stiffness and accuracy. Conventional robotic arms are often slender and cantilever structures, which greatly reduces the overall rigidity of the robot, particularly the ability to carry the load perpendicular to the arm. Robot in the machining of large parts becomes difficult. Due to the stiffness of tandem robots, the robots are limited to soft materials. In addition, the robot's accuracy could not meet the requirements of complex parts machining accuracy. For example, the accuracy of multi-degree-of-freedom hinges commonly used in robot joints is one of the factors that affect the accuracy of the entire robot. The robot's own stiffness and robot accuracy are the main problems robot faces.

3. scope of work problems

The working range refers to all the assemblies that can be reached at the end of the robot arm or the center of the wrist. The shape and size of the working area are important, and the robot may not be able to do the job because of a job dead zone that could not be reached by hand. As the robot's mobility and attitude coupled with each other, it is more difficult to calculate the working space. In the robot for machining, pay attention to the dead zone and interfere with the workpiece, the collision problem.

Shenzhen Noble smart manufacturing technology Co., Ltd. has over 10 years of experience in CNC machining.
