Hi all,
Im making a cnc maintenance dashboard for machine uptime, running issues ect. Just wondering what metrics you anybody who was doing the same and what problems you came across.
Hello @clawsonpaul which datasource you are using for machine dashboard??
Hi,
Im using node red and influx
Hi @clawsonpaul
I have been doing exactly as you, i.e. Node-RED –> InfluxDB v2.7 –> Grafana
There is probably a small book on the ‘lessons learned’ that I could publish! Is the CNC data already flowing into Node-RED? What fields are you capturing (or want to capture)? I like to calculate OEU (vs OEE) per month, whereby I can define what constitutes truly productive ‘uptime’ (unit is on, spindle load, etc.) and then simply ratio out the days (or hours) of uptime as the numerator and the total number of days (or hours) in each month as the demoninator.
Hi Grant
that’s great, i have been looking onto this for a number of years and recording data for a few. i currently get inputs from the stack lights. we have some monitoring systems for Mazaks and other CNC but i was drawn to machines that weren’t logged and process equipment that a stack light could be installed, some punch presses, laminating presses for temperature, process systems ect. From a maintenance perspective (my role) as issues were always based on word of mouth and we didn’t have history. This is what i wanted to open up, first with temp cycles, did it spike, is the controller got an issue ect, then cnc monitoring, where are are gaps and why, tool setting ect, shift differences. what is the process time, can i count the cycles of processes and grow from here. i have state timeline and take three inputs, green, amber, red and go from there to form a picture. i have another effort on the go to form OEE but this is work in progress.
