hi graemeian, this post is about osp300 ( at least )
run this code at 100% rapid, with and without the brakets
Code:
VC1 = 25
G00 X0 Y0
( VINPX = 0 )
( VINPY = 0 )
X+VC1 Y+VC1 G91
X+VC1 Y-VC1
X+VC1 Y+VC1
X+VC1 Y-VC1
X+VC1 Y+VC1
X+VC1 Y-VC1
X+VC1 Y+VC1
X+VC1 Y-VC1
X0 Y0 G90
VINPX = 0.005
VINPY = 0.005
that zig-zag toolpath should be executed more smoothly when vinp* is there
it may be a good idea to write down the vinp* values before you run this code ... so run this before :
Code:
VC1 = VINPX
VC2 = VINPY
VC3 = VINPZ write down vc1 2 3, on a piece of paper, on a dirty window, in sand ? use chalk ?
pls check attached image, so to see the interface for the vinp*
In my manual, I have VPF1C marked where I tried it before. I just tried it and no noticeable change for a G73 cycle. Somewhere, there is a parameter for heavy parts
that vpf1c seems to be a parameter that targets acc/decc for the predefined F1, when using the option "F1-digit parameter"
seems to be a limitated behaviour / whatever ...
I did not know that there is an acceleration control for rapid
check post 28 in next link ( about vinp, hig, bits, etc ): it is a bit old, but is still ok : https://www.cnczone.com/forums/okuma...precision.html
important thing : vinp*=0 delivers a smooth movement, and a cycle time comparable to when using hi-g at 100%; hi-g uses higher speeds and more agrresive acceleration, while vinp* keeps a moderate speed for a longer time
vinp is cutting corners, or is stepping on the grass ( just a bit )
about boosting a drill cycle, etc, consider reading the " cycle time reduction " chapter for mills try also this code with and without brakets
Code:
G00 Z_safe_plane
M08
S3456 M03
G00 X0 Y0
( VINPZ = 0 )
G00 Z2.5
G01 Z-5 F0.369 G95
G00 Z-5+0.3
Z+2.5
Z-5+0.6
G01 Z-10
G00 Z-10+0.3
Z+2.5
Z-10+0.6
G01 Z-15
G00 Z-15+0.3
Z+2.5
M05 M300
VINPZ = 0.005
G00 Z_safe_plane
if you replace G00s with G01s, than you may no longer see the vinp* effect, because it does not affect transition "from or to" feed movements, but only "from or to" rapid movements and static positions ( pls check attached image )
kindly
