Adaptive control safeguards CNC
machining
Adaptive control and monitoring system optimizes the roughing out and semi-finishing machining of a mould/die, as well as ensuring the absolute safety of the tool, spindle and machine tool.
The Omative Adaptive Control and Monitoring System (ACM) from Fidia optimizes the roughing out and semi-finishing processes of a mould/die, as well as ensuring the absolute safety of the tool, spindle and machine tool as regards possible collision between the tool and the workpiece Based on an intelligent system, ACM con- tinually adapts in real time the axis feed as a function of the detected spindle load, the material machined and the tool in use

CNC milling centre is stiff and accurate
Milling centre - an optimal answer combining speed and rigidity - features a cast iron structure with generously proportioned roller guides for high accuracy and stiffness.
Precision CNC milling centres range up to 4000mm
A wide range of various sizes of continuous path 3- and multi-axis CNC milling machines range from a 3-axis 600x500x400mm model to 5-axis types with up to 4000mm X-axis traverse.
Not only is it able, like normal adaptive controls, to slow down axis feed, but it can also increase the feed beyond 100% of the nominal feed if the machining situation allows it.
Absolute safety is guaranteed because ACM eliminates collisions between the tool and the part, as well as any overloading of the spindle.
The ACM system, available on Fidia numerical controls, was developed as a result of close collaboration with Omative, a company well known in the mould and die sector for its OptiMil product, from which ACM is derived.
Advantages of ACM are as follows.
* Reduction in machining time with a subsequent reduction in costs owing to modulation of the axis feed in real time.
* Tool safety - the feed is immediately stopped in the event of excessive overloading, which is a symptom of impact between the tool and the part.
* Spindle safety - by continually checking the load on the spindle, any stress on the mechanical components is avoided.
* Machine tool safety - always maintaining optimum milling conditions benefits the machine tool structure.
* Optimizing tool life - by avoiding excessive force as a result of continual feed modulation, abnormal tool wear is prevented.
* Monitoring of tool wear with an indication of the remaining 'life'.
