Feed based on maximum RPM

[Roy Zomer]

Hi there,

 

I see in Mastercam X7, the feed is calculated based on the reduced RPM. Good job!! Now I don’t have to calculate this inside the post processor. With the plunge rate not being calculated I must leave things as they were.

 

What I normally do, set the MMD file to max 100.000 RPM so I can make one tool table with the recommended RPM, FEED & PLUNGE RATE. The maximum RPM is set inside the post processor. So when the chosen RPM inside Mastercam exceeds the maximum RPM inside the post processor it let the RPM, FEED & PLUNGE RATE be calculated again to get 3 reduced values. To do this inside the post processor I can make 1 tool table, for 10 machines...no problem.

 

Am I the only one that is experiencing this? Or do we have other solutions to handle this?

 

Thanks

I haven't played with X7 yet but I do the same thing in my post along with the max feedrate. Send in a request to have plunge added.

I've already send the request, but get the reaction that this value wasn't designed to be a calculated value. So wasn't the feed rate!!!, and they've made it a calculated value in Mastercam X7. So what I believe is that this is a job half done. Trying to get reactions so I can convince Mastercam that the plunge rate needs to be a calculated value as well.
