Surface Rough Parallel

[Travis_Buchanan]

I love this tool path except for one thing. It cuts a lot of air. On the very 1st pass it cuts everything inside the boundary. After the 1st pass everything works as it should. I have been working around this for years by using surface finish parallel and copying the op then changing stock to leave on drive surfs. Am I overlooking something? Why doesn't depth cuts work in Surf Rough Par like they do in Surf Fin Par? I have also experimented with surface rough pocket, but I get plunge cuts sometimes where I dont want them. I generaly program orgin at center, center, top and I see no need to cut anything above Z0.1250. Help.

can you email me the file Travis? I"ll take a look!

Well thanks to my buddy Gcode I found a way around the air. Look at surface/rough/project. The thing here is you need to create the lines for the distance between each cut but talk about a sweet toolpath I mean it rocks. Will do everything you could want and more. You want feature left just create your center line around the feature and they are there done. It cruches longer but the wasted moves and toolpaths just are about a good as you could very want. Thanks to Gcode I got a great new tool for my toolbox.

Sometimes it helps to trim the toolpath from a different view. Toolpaths - Next Menu -Trim.

jctjct, That was cool. That is a neat trick. I have never used that before. I will use that till somebody fixes the depth cuts.

[Travis_Buchanan]

Oops, After verifying the toolpaths I see that all my retracts were trimmed as well. That ain't going to work. Back to the drawing board.

 

Ron, I have also in the past did a surface rough parallel, backplot with save as geometery on, delete all air cuts. Then toolpath contour the backplotted lines, that is a workaround as well. I just hate having to create extra geometery for a toolpath. Surface Rough Parallel needs to be fixed maybe in X.

travis, I think you can find a way around it trimming the retracts. Maybe email your file to me.

go int your cutdepths on last page and set minimum depth to start #step down into part, and max to what you need

+1 to Jimmy's response. I had the same frustation until i discovered cut depth.

Ok I put the file up on the ftp in the MC9 folder. S_R_P.mc9 The 1st op is the culprit. Ops 2,3,& 4 have been my solution to the problem for years. Jimmy I am using the cut depths, but they don't work the same as cut depths in surface finish parallel. Be sure to check all my parameter settings in srp & sfp. Notice the differance?
