Our article on DNC software functions and benefits was published by MoldMaking Technology recently. “A company’s programs are their livelihood on the shop floor. They make the parts that keep a business going.”
The three different DNC CNC benefits discussed were remote requests, compatibility (different machines and methods to use DNC), and program revision control.
We also wanted to discuss in this blog a rumor about certain DNC MACROs for manufacturing multitasking. We recommend you read the article for more in-depth information.
Operators with older machines may have limited memory and will need to drip-feed large programs with DNC. Machinists also like using DNC for remote requests or pull mode. While drip-feeding pushes the program (downloaded from the DNC server), the program can instead be requested from the CNC machine.
While remote requests and the diversity of drip-feeding make machinists jobs easier, there is also the added stress of incorrect programs being run at machines. CNC revision control controls this problem and prevents this issue from occurring.
Some operators say they can use DNC in order to perform very basic machine monitoring. Items sent via RS232 can be observed with a specific G-code function.
While this G-code function has been discussed on various machinist forums, we highly recommend you do not rely on it for monitoring CNCs. The information the MACRO provides alone is not good enough. For example – you can feel when your leg is injured, but you won’t know if it’s a sprain or a fracture until you have professional insight.
This G-code MACRO hack will not be able to tell you in-depth when machines are down, why, for how long, what processes can be improved upon, or overall efficiency of your equipment. It also can’t send notifications via email or text when machines are down. DNC can easily be integrated with OEE monitoring software for combined productivity uses.
