Hexapods in Mechanical Engineering

If multi-axis systems are required for positioning tasks in mechanical engineering, parallel-kinematic systems, so-called hexapods, are frequently used. Areas of application include, for example, handling systems in electronics production, tool control in precision machine tools, for drilling and milling, or for mounting tasks in vehicle, aircraft, or heavy equipment construction.

Adaptable and Flexible

The parent PLC or CNC can communicate with the hexapod system over a standardized real-time Ethernet interface. It then acts just like an intelligent drive. Of course, the hexapod controller can also act as master for position control. In this case, however, the motion cannot be synchronized with other drive axes, measuring systems, etc.

 

 

If there is no parent PLC or if synchronizing is not required, the hexapod controller can also plan the trajectories by means of linear interpolation based on G-code according to DIN 66025/ISO 6983.

The hexapod system allows then to move the workpiece or tool smoothly and with high precision during machining so that the mechanical system does not start to vibrate.
