Hello magicniner & routercnc,

Thank you & very kind of you for your swift reply.
Let me put my issues, very precisely now.

We use Manford CNC Bed Type Milling Machine - Tontec Technology.
Model No : Manford - VM1100 / VM1000.
You can view its specifications in the below URL.

We run 3 shifts in a day. When the tool bit looses contact with the workpiece,
the CNC machine simply runs. During this time, we want to generate an
alarm (alert) signal & stop the machine automatically, if possible.

We would like to monitor or measure, how much time is wasted in a day for this?
Looking to improve the production capacity with best cost-effective solutions.

How can this be achieved. Can it be done with program alone or any
external hardware is required? Thanks in advance.
