Merging channels to plot force over travel and getting [x,y] of a specific event

$

Hello, everybody,

for years I've been reading here quietly in the board. But this time the search function did not produce any hits.

 

Situation:
For a punching process, I measured both the cutting force and the tool travel over 400 strokes at the synchronized time. (attached are the measurement files)

 

Task:
I want to merge both signal channels and define a special event for each individual stroke (e.g. maximum) and get both the x-value (tool path) and the y-value (cutting force) for the event.

 

Problem:
1. If I convert both signal channels from waveform to numeric channels and then try to create a composite waveform channel with x-channel as path and y-channel as force, I get an equidistant error.

2. How do I get the X-value of a defined event? When I search for the maxima, I only get the corresponding force displayed, but not the corresponding x-value.

 

I hope you guys can help me.

 

Best regards

Alex
