  1. my fav as well is opti-rough the reason your gettign so many questions on tooling, etc. is because many of us have different toolpath choices depending on the tooling being used, for example i would likely use a optirough for a solid carbide roughing tool and might choose 3d area roughing for an insertable cutter. Just like i might not choose Dynamic for a machine with low amounts of memory or might exclusively choose Dynamic on a low horsepower machine. So tooling, materials, machine capabilities all effect our decisions on toolpaths as programmers which is why so many people area asking you all those questions before they answer what is best
  2. well its been almost 3 years since he posted that so im guessing that he got his answer by now, and if he hasn't i cant imagine he is still here waiting for one
  3. or capable of cheating
  4. on your tool axis control page you have chosen "to point", where it appears the proper choice is "from point" alternatively you can choose Surface for your Tool axis control setting, and then you can simply select the surface. also if your in need of some more tutorials the tutorials that this person has created are very good in my opinion if you ever would like to look over some more tutorials https://www.youtube.com/c/ASPEAeroSpacePrecisionEngineering
  5. when you say "btw, i never use MC's stupid solid pickup, always curve all edges" tells me that you have not had proper training because if you were properly trained you would most not think that way and would be using solid chaining and making your job easy instead of doing all the edge curves. So i would suggest getting some training and revisiting mastercam powerful solid chaining options. I am not saying that everyone that creates edge curves does anything wrong nor am i saying wireframe chaining is bad, im just saying that in my opinion you must not have properly learned the solid chaining in mastercam if you think that way or made a statement like that
  6. as a work around Brandon just make your Turned stock profile include enough geometry to cover the fixture, see image below. from a quick test this works well. Mayday submitted it to cnc it sounds like so maybe there will one day be a better way but i think this should do a nice job and isn't very difficult to draw the stock profile
  7. oh i see, i thought you were just looking at clamping on something that was already turned
  8. hi Brandon, the easiest thing to do in my opinion is create a profile that represents the Exact shape of your stock, then use Revolved stock for your stock setup, as long as your profile you select doesn't have stock on the end that was already cut it should clamp right where you need. Also if you turned the first side of that part in mastercam you can do a lathe stock preview to save the stock geometry or the turn profile if you dont feel like re-creating it. if none of this makes any sense what im trying to say is do it kindof like i did a stock flip in this video here https://fastechincorporated-my.sharepoint.com/:v:/g/personal/joshc_fastechinc_net/EeQzcaIJqGBKqXKRNrZhuu4B8RauXDgJZ4_JBHg7jWoL2A?e=6yjfQN
  9. if 12.75 mm (0.501968) is close enough here is one i found https://www.mscdirect.com/product/details/12666715
  10. I do not think that is a good suggestion for others though, tools should be defined accurately, I don't know if your saying that all the chamfer mills you buy go down to a .001" point but if you define the chamfer mill properly and use the toolpath properly everything works perfectly, and comes out correctly first try without having to comp the chamfer mill in any way. If your defining your tool incorrectly your going to have a not so fun time out at the machine trying to get the correct results.
  11. a point toolpath makes that simple, first create a point above the groove, on the left side of the groove, which will be your rapid point click the point toolpath choose G0 RAPID BREAK, then select the rapid point (rapid break will rapid in Z first then X) Choose G1, then select the bottom left corner of the groove Choose G0, then select the rapid point again Then check out, and set tool settings
  12. its probably a boundary from the toolpath control page preventing that path from cutting the entire surface. Also sometimes i also turn off Optimize cut order to get a slightly different result from Hybrid set to flats only as well.
  13. You can set the hybrid toolpath to do flats only, the setting is on the cut paramaters page and that will cut from the outside and only cuts flats.
  14. SLuong looking at the bottom right of your file where there is the scale or ruler are you seeing it say metric down there or inch?
