Direct Numerical Control (DNC)

Challenges on the Machine Shop Floor

Whenever Hyla Soft visits a machine shop, we can usually count on seeing at least one of these things:

  • NC programs residing on machine controllers instead of a centralized location
  • CAM engineers put their programs on a USB stick, and walk them to each machine where they could run
  • Operators know which program to run by word-of-mouth, instead of reliable documentation
  • Little or no revision control of NC programs
  • Paper-based shop documentation, such as setup sheets at machining workstations
  • Frequent equipment downtime

There are too many risks: running an outdated program, placing a program on the wrong machine, or failing an audit, to name a few. Since CNC machining manufacturers typically work with expensive equipment and materials, these risks are unacceptable. The company’s CAM engineers often know that this situation isn’t right, but aren’t sure how to best address the issues.

The answer to these problems, encountered in most machine shops, is a fully CNC machining environment, involving Direct Numerical Control (DNC) and Machine Data Acquisition (MDA).

What is Direct Numerical Control (DNC)?

The purpose of a DNC system is to provide a central repository for manufacturing and NC data, and to make this data available to the shop floor. Features of a complete DNC solution include:

  • Central management and revision control of NC programs and related CAM data
  • Direct connection from data repository to CNC machines
  • Configuration options to support customer requirements and preferences

What is Machine Data Acquisition (MDA)?

The purpose of MDA is to collect information from equipment to assist manufacturers in identifying and addressing causes of equipment problems. Features of a complete MDA solution include:

  • Central portal for accessing real-time and archived machine data
  • Real-time extraction of signals directly from shop floor equipment
  • Configurable reports to help customers understand and improve their manufacturing capabilities
