Dadoing in Melamine3/6
looking for a little CNC tooling set up advice. I am getting ready to cut a job out of Melamine ( not what we normally cut) and wanted some advice on what are some recommended bits to do some dadoing. I tried using a 2 flute low spiral down cut (1/2") and am getting a fair amount of chipping on the edge. RPM's around 18000 speed at 300Ipm. I am using a new bit but still getting the chip out issue. Anyone have a good set up they care to share? Thanks for any advice
How deep are your datos? I have used that same set up as you have with no issues at all.
We run all dados with a 2 flute plunge carbide (straight). Not sure your tool diameter but rpms may be high.
1/2" two flute down spiral.
I think we're at 16,000rpm, 800ipm
I dado with my outline tool 3/8 3 flute compression 2/10 upsheer. 16000 rpm 600 IPM. The reason being the dado has a different wear pattern than outline. I get dado tool for free. outline wear for tool is at bottom and 3/4. dado wear is at 1/4. As long as you have dados set at 1/4 or deeper this works fine.
How are you guys using a 3/8 dis bit for dado on inset backs ?
Are you not using 1/4 material for the backs?
And how are you using the same tool for dado and drill ?
Are the hole sizes for your fasteners that big ?
