Precise Acc/Dec Test

[kwolf]

Hi everybody,

 

What's the best way, in your opinion, to find the max acceleration/deceleration of a 3 axis milling machine ?

Re-running a previous program (which is an arc toolpath in 3 standard planes) with higher feed rates untill hearing gouge is what Mastercam Help suggests to find max safe feed rate (or max safe acceleration). But with different arc radius we got several different acceleration number. So we don't know exactly what the correct acc is.

Do you use another method? And please tell me details , for example the exact geometry you use.

 

Thanks in advance

What is the manufacturer?

The control?

There are several machines. Most of them are old machines back to 85-91:

The controllers are,

Dialog 11/Heidenhain 155/Mitsubishi Meldas M64.

Ever study statistics. It's possible to get close with the values you're looking for by running several different diameters. This way you'll be able to plot out how much acc. or dec. is needed based on averages or means or medians. Remember, you should hear the tool sooner on smaller diameters, these values can be used to calculate appropriate feed values.

 

Have fun and good luck...
