I am wondering if there is some way that I can share a project from carbide create with someone with more experience then me. I’m learning feeds and speeds, but I am still very confused by the concept. It could even be me picking the wrong tool path, but I am making a project with multiple designs and when I pick the tool path to cut out 2 designs with an advanced V carve tool path it is estimating over 700 minutes. I even doubled the max cut per pass.
I would be grateful if someone could look at the project and tell me if that’s just what it will take, or am I making some kind of mistake.
Is it where you are making raised letters…i.e. you have to clear a large field of material to get the letters to stand out. That will take a long time if you try to use the v-bit to clear the field. There is an option to use a square end mill to clear out the field (where it will fit). This takes quite a bit of time off the cut.
I dont have the tool path off hand, but I can say that im using an advance V carve with a 30° v bit and a 1/16 end mill. For both bits I have used the feeds and speeds that came with them. Everything bellow will be in inches
Both bits had the max depth per cut set at .025
Step over for both i dont know exactly but it was very conservative. If it helps, i am using IDC woodcraft bits
1/16 end mill
Plunge-10
Feed rate-20
Rpm-22000
30° v bit
Plunge-20
Feed rate-35
Rpm-22000
For size reference, the numbered words bellow the image are a little shy of 1/4 inch tall
not sure the attachment worked unless its just taking its sweet time, but a 1/16" bit is very small and doesnt see much use in my shop. 30 degree bit should give you plenty of detail and if you can set the depth deep enough one pass should be plenty for the bulk of that geometry
A v bit will cut the gap between two lines very effectively, but by limiting it to “Both bits had the max depth per cut set at .025” it likely means its making a billion little cuts. try setting the v bit max depth to much deeper (say .25") and see how that affects your time.
Your RPM’s, feed, DOC, plunge would seem to be reasonable if you are cutting the design out of aluminum or some other metal. But RPM’s of 2,200 are not even applicable if you are using a Makita/Dewalt/Carbide3D trim router which have an approximate range of 12,000 - 30,000RPM.
V-bits in wood can go considerably deeper & faster than what you’ve got there. I don’t really know the limits of 1/16" straight bits as I don’t have any. I prefer 1/32" taper ballnose for fine detail carving - can also be utlized as a ‘kind-of’ V-bit in CC & clearing around fine details if you keep the step-over really small(<0.200mm).
Thats my mistake. It supposed to be 22000 for both bits. I use a vfd 2.2kw spindle if that has any effect over it as well. I know it does in torque, but with the 1/16 bit I can only assume im trying to put as little torque on the bit as possible
Have you tried using the advanced vcarve tool path? this removes large amounts of stock with endmills (you can choose the size of endmill to use) then uses the vbit for the edge work.
