What is the benefit of adding force control to a machine tool?

The machining centre is designed to operate in position control. Friction stir welding requires force control, and therefore a force sensor to control the friction of the shoulder on the workpieces.
Integrated directly into the Stirweld head, this sensor measures and maintains a constant pressure. The force control allows the positioning of the tool to be adjusted according to variations in the relief of the parts to be joined. Unlike the position control of the CNC, the force control allows for adaptation to these variations.
Force control is an essential element in ensuring a high quality FSW weld. Perfect FSW welding requires control of the force exerted by the FSW head during the welding operation.
In addition, the force control provides additional safety for your machine tool. The sensor ensures that the maximum force applicable by the traditional milling machine is not reached.
