Machine: X-Carve 1000mm
Router: Dewalt 611
Software: Rhino with RhinoCAM, using X-Carve Post Processor
Tool: 1/4", 2 flute straight router bit (square bottom)
Material: melamine coated particle board (.750" thick)
- pockets are 1/16" undersize in X and Y direction
- profiles are undersize by 1/16" in X and Y direction
When I cut rectangular pockets, the X and Y dimensions are short 1/16".
The pockets I’m cutting in my part should be .750" x 2.000", but they come out as approximately 11/16" x 1-15/16".
Some are arranged vertically and some are horizontal… but they measure the same in both orientations.
When the part is cut out using the profile process, the part should measure 21" x 18", but it measures 1/16" short in both dimensions.
With profiling and pocketing being outside and inside operations, respectively… AND with the 1/16" loss being constant, regardless of X or Y direction OR dimension… I’m at a loss.
I’ve measured my tool to ensure it is .250" OD, and it is.
I figured if the tool was undersize, it would impact the pocketing and profiling in opposite ways (pocketing would be undersize and profiling would be oversize), but that’s not the case.
I figured if the gantry was twisting or the tool was deflecting, it would impact X and Y differently, but it isn’t.
Last night, I tried cutting the pockets .300" deep in two ways to compare… one pocket cut by hogging out all .300" at once, and the other way cutting it in three passes .100" deep per pass. Of course the 2nd one looked better, but the dimensions between sides was the same… 1/16" undersize in both X and Y.
I’m at a loss.
Can anyone give me some advice?
I’m going to go through calibration again, this week and see what that yields, but I’m looking for anything before I go too far in any direction.
Thank you, in advance for your help and input.
