Way to calculate decelleration distance?

Post by SamMarrocco » Sat Oct 17, 2020 10:39 pm

I'm using G32 to cut a thread based upon the constant speed of my spindle. I know the start and end points over which I want the threads to be equally spaced. Knowing that the KFlop accelerates up to cutting speed and then down from that speed, is there a way, given the constant speed in IPM that I can calculate the exact distance of the acceleration and deceleration portions of the travel?

Hi Sam,

It should be dist = V^2 / 2A

where V = feedrate in units/sec and A is max acceleration in units/s^2

Thank you, Tom.
I'm going to use that in some path tracing code I've added to my CNC app for the KFlop for some interesting visuals.
