There are no estimates on how many CNC-certified workers are needed, but an aging manufacturing workforce and wave of baby boomer retirements in coming years is expected to increase demand.

Last year, the state Legislature appropriated $18.75 million to an Advanced Manufacturing Futures Fund to help firms and employees deal with technological changes requiring new training, equipment, and other assistance.
