Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

[JOGARA]

Nice. Looks like the vice is giving you much better results so worth every penny if it gets the job done.

For chatter if you're using HSM toolpaths full depth and shallow step over try using a bigger 8mm or 10mm tool. 6mm drill should be absolutely fine, I have absolutely zero problems doing a 6.

Yea it was a sound investment.

While it sounded like there was chatter, I could not feel anything in the part. Though I did do a contour finishing pass which would have hidden it I guess.

As for HSM, idk if that is what I am doing or not. Not sure what classes HSM. Currently I am taking a DOC that is 50% the width of the tool with a 45% step over.


The only problem I am having ATM is doing a chamfer. For some reason it is quite uneven around the part.
Looks like the part when clamped is lifting a hair but even so, it is low on that corner.
Can only guess that it is not being perfectly probed or the vice is out by a hair?
