NUM’s CNC axis sharing brings machine versatility

The NUM CNC axis sharing facility provides a means of controlling a high number of functionally interrelated groups of motion axes by using dynamic resource allocation techniques to share control across multiple CNC kernels.

The facility extends NUM’s Flexium+ 68 CNC architecture by allowing the control of up to 32 servo drives to be timeshared by any of the CNC kernels in the system.

Until now, it was only possible to share control of axes across the eight CNC channels of each individual Flexium+ 68 CNC kernel in a system. However, some machining centres and rotary transfer machines have a high number of stations, each typically comprising a multi-axis head that is shared by separate machining units in each station.

Each unit is best served by having its own dedicated CNC channel, with control of the shared multi-axis heads being passed from one channel to another as the cycle progresses.
