New CNC kernel for small to medium size machines

Written by: Laura Hopperton | Published:

NUM has extended its Flexium+ family of CNC kernels with a new hardware configuration option for small to medium size machines.

The new Flexium+ 8 CNC kernel is designed specifically for machine applications that require movement of up to five axes. In terms of control flexibility, it is comparable to NUM's most powerful CNC kernel, the Flexium+ 68, and can be used with all Flexium+ compatible hardware and software.

The module offers two CNC channels and accommodates up to four simultaneously interpolated axes. It can also be configured to handle more complex types of interpolation such as Spline and NURBS, and offers various options and technology packages.

At any one time, either CNC channel can be used to control a spindle motor and four axes, instead of the full complement of five axes. This, according to NUM, simplifies the design of complex machines with multiple synchronisation requirements by allowing easy control partitioning.

For example, on a thread or gear cutting machine, one channel could control two axes and a spindle to perform the process functions, while the second channel could be used to control two feed axes.

Each channel can run its own part program asynchronously and operate autonomously. Or, the two channels can be synchronised. Control of one to five axes, or a spindle, can be passed on-the-fly from one channel to the other, to maximise use of available hardware resources.
