DNC System for a Fabrication Industry Shop
Company B is a contract fabrication shop with 7 CNC machines, running two shifts in support of their fabrication operations. All CNC programming was being done at the machine controls, with the programs then residing on the machine control memory, often without back-up copies. After a number of years the memories of their CNC machines became full, so whenever a new program needed to be created an older program had to be deleted from a control memory. The CNC programs written at Company B were usually very complicated and time consuming, usually requiring a minimum of about 5 hours to write, proof and optimize each program.
After several critical programs without back-up copies were deleted from the CNC controls, the frustrated programmers convinced Company B to research a DNC system to manage their CNC programs. When someone in management finally ran the numbers to discover the value loss that occurred whenever a non-backed up CNC program was deleted from a CNC control, the investment into a DNC system made perfect sense. The calculation below allowed Company B to realize that losing just 1 CNC program per week, would amount to a yearly loss of over $100K. Comparatively, the one-time upfront investment of less than $7K for an eNETDNC system for guaranteed CNC file management was a no-brainer.
