Re: [Emc-users] Freecad path workbench + drilling small hole
Spot drills are also available in carbide which is much stiffer than a HSS spot drill. For best accuracy, the tip angle of the spot drill should be greater than the angle of your drill. That is, for a 118-degree drill a spot drill of 120 degrees or more is best. -Original Message- From: Nicklas SB Karlsson Sent: October 20, 2022 2:11 PM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] Freecad path workbench + drilling small hole Center drill is 60 degree angle. It have thick shaft which is good but thinner tip. Spot drill is 90 degree angle and have found statements it is made fo precise bore hole placement so muste be a good choice.

Re: [Emc-users] Freecad path workbench + drilling small hole
Use a spot drill before the small drill to get the hole on center and true. "Real" CAM software usually lets you select spot drilling for each hole. Then it generates tool path for the spot drill operation before tool path for the regular drill. I would love for FreeCAD to gain the features other CAD/CAM software has. I keep trying it out, but keep getting stuck with some key missing piece. I haven't made the commitment to get involved in development though. They came out with a new release fairly recently, so I believe it is under active development. -- Ralph From: Nicklas SB Karlsson [n...@nksb.eu] Sent: Thursday, October 20, 2022 7:23 AM To: emc-users@lists.sourceforge.net Subject: [Emc-users] Freecad path workbench + drilling small hole CAUTION: This email originated from outside the Walla Walla University email system.

I think he was asking about how to modify FreeCAD software, not how to drill a hole. Perhaps modify the G-code generator to do as you say and add a tool-change. But how does the planner know when best to change the tool? FreeCAD's path planner is pretty good but still in the early stages. I know many people like to hand-code g-code files, but just try to make the housing for a battery-powered electric drill with hand-written g-code. One side of the housing is very mechanical with bearing and motor supports and blind thread and the outside is all organic compound curves. -- Chris Albertson Redondo Beach, California ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
