Large Lathe Retrofit
I am interested too in doing this, because i am planning to use the lathe in a production environment (not hobby).
for improving our cutting processes is to mount an accelerometer and a vibration sensor on the tool post so that I may measure chatter in order to identify situations that cause vibration or chatter and improve our cutting parameter selection. It would be interesting if I could for instance identify the vibration signature of when an insert wears out or breaks and then possibly output an error message on the user interface, retract the tool post or even stop the job immediately if the case warrants it.
Right now i am testing to measure the motor load in order to know if i can improve the feed or speed in some parts of the program.
I am measuring it througth modbus, because the servo drive have an Rs-485 port (rs232 too) and export it in registers.
Some time ago i was searching some advanced products but they are expensive
A first step could be implemented in LinuxCNC attaching an acelerometer to the A / D input card and showing the values.
A more sophisticated product may be a FPGA card that convert the input in mm/sec (or mm/sec2?) and a program like the showed in youtube (ATAMsystems) running in userspace and connected to HAL.
May be somebody that read this post could help us
Excuseme for my english
