StripeHatcher¶

class pyslm.hatching.StripeHatcher¶

Bases: pyslm.hatching.hatching.Hatcher

The Stripe Hatcher extends the standard Hatcher but generates a set of stripe hatches of a fixed width (stripeWidth) to cover a region. This a common scan strategy adopted by users of EOS systems. This has the effect of limiting the max length of the scan vectors across a region in order to mitigate the effects of residual stress.

Attributes Summary

`stripeOffset`	The stripe offset is the relative distance (hatch spacing) to move the scan vectors between adjacent stripes
`stripeOverlap`	The length of overlap between adjacent stripes
`stripeWidth`	The stripe width

Methods Summary

generateHatching(paths, hatchSpacing[, …])

Generates un-clipped hatches which is guaranteed to cover the entire polygon region based on the maximum extent of the polygon bounding box
