Fining-off etc. influences to become apparent for the laser processing of focal position sensitivity, and focal position of laser directly influences section
Roughness, the gradient of joint-cutting, width and the relevant processing quality such as attachment for melting residue.
Traditional laser process equipment is all pre-set focal position, processes before starting focus lamp moving on to default position
It postponing and starts to process, focal position of laser cannot change in process, once focus lamp is relative to rapidoprint surface
Distance changes and causes out of focus, needs to readjust focus lamp position, thus it is more serious affect processing quality and plus
Work efficiency rate;Focus lamp changes relative to the distance on rapidoprint surface and is mainly the following possibility:First, placing processing
The flatness of the platform of material is bad, as Working position difference causes distance to change;Second is that rapidoprint concave-convex surface
Injustice causes distance to change;Third, causing distance to change with the variation of working depth in process, this three
Kind variation can all cause focal position of laser to change.However, the focus position for the processing technology of focal position sensitivity
Set change be clearly be difficult to meet processing criterion, thus the problem be also restrict a great influence of processing uniformity because
Element.
