Hello!

I've got some request to cuts fabric, leather and linoleum and I'm in the process of making a tangential knife for this application.

I've got a 130x260 cnc router with a vacuum bed so fixing the material should not be a problem.

I started with a simple dragknife but was not satisfied. After reading the Eding CNC manual I had a tangential knife output to point the knife in the right direction with a steppermotor in under a hour and this is much cleaner way of cutting materials.

I've got all the hardware (stepper, knifeholder, some bearings etc) but I was thinking to upgrade the system with a oscillating movement or maybe even a ultrasonic movement.

In this video you see a ultrasonic knife.

I don't have a ultrasonic cleaner but let's say I remove the piezo element and attached it to a blade and find the right frequency for cutting. Would it be that simple?

I can't find real information on the internet but when I do find it I will post it in this topic.
