Safe Operations to use in a chook or NEThook : Mastercam 2018

[Guest]

This is the results of which operations I validated as stable or safe to use :

Circle Mill <- not approved this operation has some issues of unknown origin with user defaults and api generated operations (Mastercam 2018)
//removed operation we will no longer use this, use pocket or contour ramp instead

Helix Bore <- not approved this operation has some issues with user defaults and api generated operations (Mastercam 2018)
//removed operation we will no longer use this, use pocket or contour ramp instead

.Net Drilling <- yes this operation is approved, no issues

.Net Contour (2d , oscillation) <- yes this operation is approved, no issues

.Net Pocket <- yes this operation is approved, no issues

Not sure what happened with the helix bore and circle mill, in my machine and some of my friends it was okay but for other people they would get giant circular toolpaths spawning for no reason, especially inside of nesting, this is a bug we have seen prior to our implementation of chooks so we know it is a bug in the operation helix bore and circle milling, if the operation is regenerated on my machine it is fine, anyway I reprogrammed all my chooks to only use pockets ,contours and simple drilling, this way there won't be any problems, my initial project written in vbscript actually did the same thing.

Mick, I am not convinced the defect is with the SDK or NEThook api, It appears to happen exclusively with circle mill , helix bore ops sometimes without the api.. Is it an ICentral ticket I need to request?

Our reseller is IHS, I sent them an email.

FYI : these were the results of extensive tests on the mastercam 2018 version involving 5 users over a one month period. The glitch appears only in about 5 percent of instances for 2 users.

Soo, I had an occurence of the same phenomenon today.. and I realize what the root cause is, if there are duplicate points in the drilltype toolpath random toolpaths can spawn from the origin. In this case it was my fault I failed to realize I needed to check that the entity was not blank, I also added a an if statement to check if the arc has a radius greater than zero.
