Edge break at end and/or beginning of toolpath without geometry creation.

Programinator · January 06, 2021, 05:12 AM

Hi. What would be really cool would be to have the option to put a corner break at the end and/or beginning of an open chain. Either a chamfer or radius.
So you could get something like this by just chaining a single solid edge or wireframe line.

Not a fan...

Heck there are users that don't check their cutter comp settings, blow parts and blame the software.

I cant imagine what would happen the 1st time sometime missed it and crashed through a wall

How could you ever blame the software for that mistake. If someone could blame the software for that then they could blame it for not showing up on time to work.

Just like a lot of the other features of the software, if someone does not like it then they don't have to use it.

If all the things that could cause a crash were taken out of the software then it would cease to exist.

Have you asked on the official Mastercam forum? You may be able to put in a feature request.

I have asked on the official forum.... But as you know there is not a lot of action over there! Get more feedback here

edge break the solid and use solid chain.
maybe

Matthew Hajicek · January 06, 2021, 08:04 AM

I'm pretty old school, I'll just make the geometry. More control that way.

I am not a fan of solid chaining....still old school.

Programinator · January 06, 2021, 08:21 AM

I know how to edit the model or create wireframe to make it do what I want. It gets a bit repetitive though. I just thought that if it was an option then it would save some time. Its not a big deal. I just think it would be a nice improvement to the software that I would use a lot.

The answer is "Yes, you can fake it", but only in Mastercam 2021 and newer.

Since Mastercam started, you could only do "tangent arcs, that are connected to a tangent or perpendicular line", when using Lead in/out.

Recently, the Lead In/Out "Arc Sweep" parameter, has been enhanced, to now allow a Negative Sweep Angle. This option is used to allow the tool to "roll into the cut", but in your case, you can use it to "round the corner", of a single straight line.

However, it is not as straight-forward, as you might desire, but it will work.

Use a Negative Arc Sweep, to reverse the Arc Entry, and use the Lead In/Out "line", to give your cutter the "approach and exit" moves, from the reversed entry/exit arcs.

NOTE: for this to work, your Entry/Exit Arc Radius, must be equal to your Tool Radius, or the tangency of that cutter versus the "line being cut", will end up in the wrong spot.

JACKOFFALLTRADES · January 06, 2021, 11:53 AM

If you want to put, say a 0.040 Arc Radius on the line, make your Lead In/Out Arc (Cutter Radius - Fillet Radius), and this should give you what you are after...

lol Same here. I probably spend more time creating geometry to control tool path than I would like to admit.

Yup. I'm not what I'd term a "lazy programmer." I want to control my programs to the final detail.
To me, that's why Solid Chaining will never catch on with me....it's lazy, it lacks control and it's not really conducive on the geometries that I deal with on a daily basis.

I'm glad you put it that way because here I thought that I was just making a lot of work for myself.

Doing it in X9 with access keys it's pretty darned fast. Back when I used to demo and instruct for Prototek and Dunwoody I got tons of amazed comments about how fast I was.
