Does it matter what side of the 4th axis that you cut on?

Post by hmatyas »

On my CNC's 4th axis I cut from the top; however, I was thinking of using some profile cutters that will cut from the side. So I was wondering if it matters on what side of the headstock you place the router on because of how the router is spinning?

Shouldn't matter what side the headstock is placed unless you're engraving letters or number, which could be reversed. However, you should be able to change settings in your Post Processor to correct that.

For side cutting it is a climb-cut vs. conventional choice, so it also matters if you are moving from headstock to tailstock, or tailstock to headstock.

If you are moving from headstock to tailstock, what side should you be on? I am hoping the left side so it will be simple to zero x and y.

Thank you.

Compare cut quality of head-to-tail vs tail-to-hear movements. Use the one that has better quality (if it makes any visible difference).
