I am getting really tired of making the same parts i have been making
for 7 years. the only fun is making improvements. So I decided to work
on my gcode and clean it up and optimize tool motion. gets a little
scary when i get close to a fixture but i managed with no crashes.
I was previously (last many years) using various feed speeds and then
using feed override to get the speeds i really wanted. it has taken
years to fine tune the speeds to deal with varying grain etc etc.
BTW, running mach4 with ESS
So i changed every F command to double what it was and ran the program.
I think i notice a significant improvement in finish. Specifically i was
getting long wood fiber threads on the top surfaces (upcutter but
ordered a bunch of other bits to try including expensive ones by Vortex.
This makes no sense to me but i have only cut 10 parts. Usually 5 are OK
and then one has some strange grain pattern in it and it comes out
stringy but after doubling the speeds (still that same speed in the end
because i use FRO of 100%) i have not had a stringy part and the finish
elsewhere looks better?
Am i hallucinating?
Quite likely -- - - nope!
A high quality cutter has a sweet spot for usage - - - - you're cutting wood
by the sound of it so I've got no ideas as to speeds/feeds. If you were
asking for metals - - - - I'd have some suggestions.
There are cutters out there that deliver scary results - - - - think
like liters of
Aluminum chip in no time flat - - - - takes some serious power and
rigidity but doable. Are many people using this level of production - - - nope!
So - - - - what are you cutting?
How rigid is your workholding/machine?
More later!
