slot depth cuts

[FTI2007]

I have done this before but cannot remember how I did it.  I have .395 wide slots that I want to rough with a .375 emill buy dropping in a pre drilled hole on on end and going straight to a pre drilled hole in the other end of the slot , then drop down to the next depth cut and come back to the starting point etc until the desired depth is reached. thanks

Contour ramp plunge setting

Edited June 7, 2016 by Guest
Get spelling of setting correct

Using 2D Contour you can set the Contour Type to Ramp on the Cut Parameters page. If I remember correctly if you pick just the one 1 line it will drop down at each end of the line for each pass and if you pick that line, up & back per se, it will only drop down at the staring point.

I tried but couldnt get what I want.  I dont want to ramp at an angle. For example .  If I want to do .500" depth cuts. So I want to drop in to .500 deep . cut to the end of the slot, then drop to 1.00 deep and come back  without any retracts or extra moves.  Which setting am I missing. when I do it it cuts only 1 direction and retracts back to the start and then goes to the next depth cut.     I am only picking 1 straight line down the center of the slot.

I think I found it.  I chose ramp and then set it to plunge and seems to do what I want.

Now I feel stupid... I always wondered if MC could do that, I tried it because of this thread and it can...sigh... Learn something new every day...

It doesn't seem logical to have a contour "ramp" toolpath then to set it to plunge... but IT WORKS !

Thats why  Inever realized that it could do it...plunge on a ramp? o_O lol

another way to mill a slot provided you're driving the tool back and forth down the middle of the slot and not contouring it, is to use ruled in wireframe toolpaths. ruled works very well for plunge roughing slots too. 

 

caveat - USE CAUTION when using wireframe toolpaths in anything but the system top WCS.

Why?

Why?

 

when using wireframe toolpaths in a non system top WCS, play close attention to rapid movements. i've randomly ran into the feed motion being correct in the proper planes while the rapid movements were relative to the system top plane. first time it happened to me i had a machine try to rapid to a position under a vise in the table after a ruled toolpath was finished. also watch out for exploding arcs though they are much more obvious than errant rapid moves. i've submitted bug reports to qc@ about these things and though they've been acknowledged and are in the database, apparently there is no intention of ever fixing them because creating an all new interface is several orders of magnitude more important than fixing bugs which have been around for more than a decade.

 

thanks for asking.

several years ago they sent out a survey asking if people still used the legacy toolpaths

they were trying to decide if they got enough use to warrant upgrading them to the new tree interface

or if they could kill them altogether

They didn't get upgraded, and the didn't get killed either

I hope they never git rid of the wireframe toolpaths, they may be outdated but I still use them.  Sometimes when you want a simple profile machined they are a lot quicker to program, and more tidy than the surface toolpaths
