So anyone have some good filter and smoothing settings for this part? Looking for a good finish and acurate part with minimal code useing surface high speed scallop. I was going to try a total tolerance of .005 with a cut tolerance of .00025, line/arc tolerance of .0007 and smoothing of .004.

Here is one example of the part .....P20 Steel EXAMPLE.MCX-7

Every toolpath has its place. I just want to focus on the filter settings to reduce code but still get an acurate part. I would think everyone would want a good part with least amount of code possible. Like in previous versions when you picked rough better best on the filter page. To me that makes more sense.

I just found this posted by colin also....... Maybe this is where I came up with a tight totol tolerance. Unless Im reading it wrong... (Copied and pasted) No, I'm not saying you need to never use Hybrid. I'm saying you should set the Horizontal Arcs setting to zero for the linking parameters. That should prevent the issue from showing up in X6. This issue has been fixed in X7, and all linking moves are now gouge checked against the drive and check surfaces. (BTW, X7 also now supports check surfaces for these HST toolpaths) I prefer the 2:1 ratio when setting my filter, as it keeps the path more accurate, while allowing better arc filtering. You can do a search on this forum for information about the toolpath filter and find some great info. There are basically two filters that run when you make a toolpath. First, the entire path is linearized, using the 'cut tolerance'. This is a bi-lateral tolerance that determines the initial accuracy of your toolpath. After the cut tolerance filter runs, then the Arc Filter is run. This filter will fit an arc to the linear segments, within the given tolerance. My basic starting parameters for Total Tolerance is 10% of the Stock to Leave value. So if you are leaving .100 of stock on your surfaces, then using .009 for the total tolerance is a good value. The larger the tolerance, the more filtered your code is. For finishing, I like to use a value of .0003 for most contouring/surfacing. The only exception for me is very tight tolerance cuts. In that case I will go down to .00001 or less for my total tolerance, basically whatever the lowest tolerance the dialog will let me enter. The ratios you choose just take the total tolerance and divide that value up between the two different filters according to the ratio you select or enter. Hope that helps, Colin

I have played alittle with the HST toolpaths for roughing but have not had much luck in steel. I think mostly because we only have general purpose Garr. Roughing is not the problem. just trying to speed up finishing.

So If set the total tolerance to .010 and slide the bar so my cut tolerance is .0005 what will my end result be? Will it be acureate to could it be .005-.009 off from the cad?? Thats where I get confused I guess. I dont have a way of measureing the final result.

Of course I rough the surface down leaving .020 for finishing. Im not sure where that roughing comment came from K2cq7. These blocks are p20 that start out over 1500lbs and finsh at 2-300lbs. AJX feed mills love these. I was thinking total tolerance was like the finished machined surface compared to the cad. So that is why I have it set to .0005. If I open it up to .01 like he says with his settings I do see wthere if you move the slider the cut tolerance stays at .0005. ...So my acuracy should stay the same Correct?? thanks again for the comments.

Im not sure how to take a screen shot. All I do Know is that the I need accurate parts with a good finish. I usually use a total tolerance of .0005 on the filter page and leave the sliders in there default location which is a cut tolerance of 90.2% (.000451) line/arc tolerance of 4.8% (.000024) and smoothing tolerance of 5.% (.000025). I have create arcs in XY checked with a minum arc radius of .005 and max arc radius of 100. use max value for both is checked. smoothing settings is checked with shift points randomly and minimize number of points. I think the hole filter page should have more info to go with it on how and when to use what setttings. everything I make is custom 1 off parts and I dont get time to experiment much settings. I hope this helps explain what im currently doing. Answers like filter filter filter do not do me any good without some direction. Thanks

I am trying to find a way to produce less code in my 3d surfacing programs. I use surface high speed scallop for alot of the parts I make. The machine we run the larger parts through does not have look ahead and really bogs down running some of the parts. sometimes down to only a couple inches a minute. I do filter the code but maybe there is somthing Im missing or doing wrong. any help would be great. Thanks

thanks

A while back I used the chook for V7 colors. How do I undo or switch it back to standard colors. Thanks

im confused to. we also thought that when we bought the high speed option it would take care of it. Now it sounds like we need to add a bunch of codes to get the machine to run properly. Hopefully someone here can take the time to explain this to us.

Now I am starting to understand why our Haas slow down so much and never make it to the programed feed rates. Where I work they just always said it was just because its a haas. So I never questioned it. Can you Please go in to more detail about the codes needed and what they do and where to put them. Maybe an example would be great also. Thanks

I wonder where the price of a DMG DMU 50/70 start? looks like a good machine. I just think with our tight budget it would be to high for us.

Briefly spoke with the local haas salesman today. He said the UMC-750 takes about 7-8 months to get. haas is selling 1-2 a day and building 1-2 a week. They even changed over one of there plants to build more UMC-750s. It use to take 10 months to get one. They even have the only one in the state in house for a show at the end of the month that is already sold but atleast we will get to see one in person and compare it next to some higher end machines that they also sell.

Dwain Dyer, that machine looks very similar to the haaas umc-750. I didnt look at all the specs yet but I look forward to hearing about how it works for you guys. What machine are you waiting for ?

below the reply box there is a white box on the right that says "more reply options". click that and at the bottom you have options to for attachments.

Gizmo, do you have any pics of the setup with the trunion and the kurts. Im having trouble pictureing all that fitting on the table. we have a vf4ss and vf5ss both 40 taper. i would think the trunion would get in the way of the kurts the way Im pictureing it.

Here is an example file I happen to be working on today. Assuming the holes are already in it and its bolted down to a fixture plate. Is this to much to ask of a haas to machine accuratley? Only 1 part. This is just 1 of 6 blocks that get bolted together as assembly to hold a plastic part so it can be welded to anouther plastic part. we have no way of checking our parts except measuring the flats/square areas and fitting the plastic part into the assembly. The parts do not always match the data we cut to since plastic odviously changes shape a little after it comes out of a mold and cools. So it is not uncommon to have to recut parts anywhere from .005-.05 larger to get them to fit. EXAMPLE.MCX-7

anybody have any input one the Haas UMC-750. It has 3 times the weight capacity of the VF5/TR

We cut 50% steel and 50% aluminum. Nothing to special. right now I end up either bolting blocks down or putting them in a vice to work on sides and the top of a block. were hoping to save some time by doing 1 setup. Also on some blocks I end up having to use some pretty long tools to get in corners that We think with a 5x we could simply tilt the block and shorten up the tools to save time and get better finishes. parts vary in size from maybe a 2l x 2w x 2h to 8w x12L x 6H with the ocassinoal larger. I just did somthing that was 7w x 26l x 5h that I had to use a sine plate to put some angled holes and pockets in the long direction. But I dont expect that to fit in most machines.

the tightest we get is +- .0005 on some bores

I should have mentioned we do not run production. mostly 1 or 2. at most maybe 10. most of our parts are +- .005. which is why we run haas. I just like to keep my options open.

I will check that out. Thanks

The boss said we might finnaly look into getting our first 5 axis (3+2) machine. Nobody here as any experience with these so I am looking for any advise on these. We do not do high tolereance work but we do alot of 3d work. We currently have mainly haas mills and couple older fadals. So I think we will mainly be looking at a Haas VF-5/40TR. I wouldnt mind also checking prices and comparing Mazak and Makino but I have no idea if they would even compare on price. Any advise on the haas or others that would be close in price to the Haas would be great. Also some ideas on what to expect on tooling and fixtureing since this would all be new to us. Also is thru spindle coolant worth the price? We have never had that either. I also assume some type of gcode verification software would be needed.? It pretty much all comes down to $$ in the end for this place so I just want to make sure they know what to expect if they come asking questions. Thanks
