    Default jerky tool paths

    hi all, im experiencing jerky tool paths, it looks like the machine is coming to a dead stop at each transition between G01, G02, G03, ect. how do i make the machine contour smoothly? or is it even a machine issue?

    you could try hi cut pro either thru program or in the parameters
    here is where if you are using mastercam/esprit of other software
    limit the number of points that have to be read by changing the cam program to out put less code
    most controls are limited to a certain number of blocks that can be read ahead
    try to make longer moves to allow the machine to keep going


    G130 TURNS IT ON IN THE PROGRAM
    G131 TURNS IT OFF
    G130FxxxxExxxxJ2
    F(UPPER FEED RATE)
    E(MACHINING TOLERANCE)
    J(1= STANDARD, 2=HIGH SPEED)

    This may smooth out the acceleration/ deceleration going from point to point

    hy jay dizzle, if you wish, pls try to find a toolpath made of 3-4-few entitites, that behaves slowly, and share the code

    from another point of view, you could calculate the lenght of the toolpath and the required cutting time, considerind feed = constant; use this as a base line; from here :
    ... scale ( up / down ) the toolpaths
    ... change the feed rate ( up / down )

    if all ok, a toolpath scaled 2 times, with a feed decreased 2 times should perform 4 times slower; idea is to find the " scale and/or feed value " where linearity is lost ( for example, if scale is too little, or feed is too high, linearity is lost ); when that point is found, pls share the code / kindly

    ps : using the hi-cut pro should be ok as long as linearity is there, but even so, using this function does not guarantee a better overall cycle time / depends

    ps2 : there are a few parameters and special functions that can smooth out movement, but i would check that code is as smooth as possible before activating those; for example, if you activate a motion controll function and you reduce cycle time, you may get an overall time slower then a simple g-code that is smoothed

    ps3 : ultimate special function to boost hi-resolution segmented code is the hyper-surface : check this out : https://www.cnczone.com/forums/okuma...novations.html
