If your corner rounding is set too tight you will have jerky moves. G187 controls the smoothness, Smooth medium or rough and also controls the corner rounding tolerance. I control mine through the coolant page. If I am doing a rough pocket I open up the tolerance in the corner rounding setting so it will not stop in the corners. Look up G187 in your manual. Smooth, medium, or fine use different accel, decel parameters and you can see the different parameters that the control uses in the back of your manual.

Thanks David, I have the G53 now. I can remove the spaces in the tool table by using the control definition but then I also remove the spaces from the rest of the program. The haas control is throwing an alarm with the extra spaces at the start of the program. The control still takes the program but its annoying.

I would like to ask for help on changing 2 things in my haas generic mill post, 1) I need to remove the spaces before and after the tool comment ( T18 | 5/16" FLAT | H18 ) should look like this (T18 | 5/16" FLAT | H18) I have removed the spaces from the rest of the comments shown below but I am not sure how to remove the spaces after and before the ( ) in the tool comment. % O0001(1) (TIME - 4:16 PM) (NC FILE - F:1.NC) ( T18 | 5/16" FLAT | H18 ) 2) I would also like to add a G53 X-13. on the next line after the G28 Y0. M9 M5 G91 G28 Z0. G28 Y0. M30 % Thanks

I already did a few months ago. If anyone else can send in an email that would be great. I think this feature would greatly reduce the risk of a crash and make programming a much easier task. Thanks...

It seems like a very important function that is totally overlooked. I have read the previous discussions but I am surprised Mastercam has not addressed this issue. If they can figure out complex multiaxis toolpaths, then why cant they figure out how to link a toolholder definition to a tool? I like Mastercam but this is a very important feature that needs to be made a priority.

Why have an option to define a toolholder if it doesn't work? If it will not work why doesn't mastercam blank out the option. If I am new to mastercam and I define a toolholder that is .1 OD over the default toolholder, I backplot and verify, all looks good, run program and smash? I know you can work around but what's the point of having the fields open? Any comments? [ 10-21-2007, 08:22 PM: Message edited by: mechman ]

I have a Haas mill with minimum oil machining (squirts a small amount of oil on the tap) and programmable air blast. Does the post need to be modified to turn these coolant commands on/off and what should it look like? Also in the coolant section of a tool in mastercam, I see the option for custom is blanked out, how do I enable the custom option for the air blast and oil coolant options? I need to turn these M functions on and off just like flood coolant.

Hello, I am new to the High Feed toolpath option... I tried it today for the first time and the toolpath looked all messed up... Did a search and here I am... This is a surface rough pocket with high speed selected as the cut style. When I tried to run it through the high feed option it made a bunch of arc moves on the backplot... I don't know if I have something set wrong or if this is the same problem the previous post had... I will try some different toolpaths tomorrow.

I have an older machine with 9600 for drip feed... I was thinking of posting R instead of IJK to shorten up the code... I set the break arc to 180... Any problems associated with doing this... I already removed the line numbers and spaces...

I will get the probe option with this mill and I am curious how this will integrate... I need to check for any z axis drift mid program at the tool change... I found some chooks for inspection and was wondering if I would need something like this program or is it unnecessary? http://www.verisurf.com/measure.htm [ 05-07-2007, 11:28 PM: Message edited by: mechman ]

Thanks, I will try the mpmaster...

I found this on another forum and thought you might be interested... Starts off slow so forward to the halfway point... http://autobeatvideo.blogspot.com/2007/04/...from-solid.html

Hello, I have a haas vertical and I am curious what the advantage of using a post like MPMASTER is over using the standard Haas generic included with mastercam... If I use the MPMASTER post what will I have to change to have it working ok... I think I will need to change the peck drill to haas and shut the 4th axis off.... I don't know much about the posts but I assume the MPMASTER may be more customizable than the generic haas and that is why some would prefer? Sorry for the newbie question....

Thanks... If I import a solid and I don't get history I guess I am stuck changing the solid to surfaces. Any point in using the solid to make toolpaths if it is not associative?

I am new to mastercam solids... I imported a solid works file but no history tree so I had to change solid to surfaces... I looked on the mastercam website about the solids and read this "Open SolidWorks® and Solid Edge® files directly, and even import history trees using the free Mastercam Direct links" how do I get the solid works tree?... Thanks in advance...
