I want my post to put the associated A Value on the opening line of a program, so that when it posts it looks like this: N130 G0 G90 G54 X.368 Y-.5 A0. S350 M3 I changed my post and put in the pfcout command to do that, but it will only post that value if it is greater than 0. I want it to post no matter if it is 0 or not. To get it to post zero I had to go in and put a "A0." in. The reason is that if I start a drilling cycle and then stop, and if the A axis is at 6 degrees, if I restart my drill cycle instead of going back to A0., it just stays at A6. and the hole is drilled in the wrong location.

That would be it. I just wondering why now all of a sudden it is posting a negative value. Didn't do that before in MR1, I'll have to look into it. Thanks guys.

When I go to run a drilling cycle on my HAAS VF-4. When I get to this line of code: N150 G98 G83 Z1.4418 R2.5418 Q-.25 F12.0 I get a range error alarm on my machine. Anybody know why or what is causing this???

I just installed MR2 and now when I start up X i am getting: Warning: Authorizaton Period on the SIM ends in 14 days. What the heck is this? I have not had a crash from X in about 2 months. With in about 5 minutes of working with MR2, I had a crash on a backplot. When I select my ops, and go into back plot to get a figure on machining time, there is nothing in backplot. What is going on here?

Not sure what you mean? Load what to Mastercam X from where? Need to be more precise.

Although the best post is probably gonna be one that is tailored to your operation. it all depends on what you are looking for and how you want it to post. mpmaster like i mentioned above is a generic post that works for HAAS machines. You can edit the post to work the way you want it to, or have someone do that for you, but then you are looking to spend some bucks.

MPMaster is probably what you are looking for.

I making some parts our of 6061 aluminum. They have 8 slots in them that is cut with a .75 ball endmill. I am going to rough them out with Roughing Endmills that range from .25 to .625. What kinds of feeds should I run with these roughing endmills as opposed to regular flat endmills. FOr my .626 rougher endmill, I am taking a .225 depth of cut. Thinking about running 1800 RPM and about 22 inches a minute. Does this sound good, or can I go faster or slower or what? Not much experience with roughing endmills. Thanks in advance.

Welcome to the forum

Taaaaa Daaaaaa. This is what I should be getting, but I have to create a whole new drawing so that Mastercam does not refer back to old data. N150 G98 G81 Z2.2768 R2.5418 F1.1 N160 X-.466 A-6. N170 X1.202 A6. N180 X2.036 A12. N190 X2.87 A18. N200 X3.704 A24. N210 X4.538 A30. N220 X5.372 A36. N230 X6.206 A42. N240 X7.04 A48. N250 X7.874 A54. N260 X8.708 A60.

I talked about this before, but I know that I have the drawing correct, but Mastercam is still messing it up. I am creating a new drawing from an already existing drawing. The first thing I did was delete all the old geometry that I did not need and only kept one entity that I needed. I then deleted all of the old T-Planes and began to draw. I created a cylinder for my stock and placed points along the outside of the cylinder in 6 degree increments. I use these to loacte a tranformed toolpath. The old drawing the increment was 6.008 degrees. Even though the new increment is now 6 degrees, when I post I am getting values from the old drawing and tplanes that are no longer there. My part should index from 0 to 6, 12, 18 24 etc... but it is giving he this output. N150 G98 G81 Z2.2768 R2.5418 F1.1 N160 X1.202 Y-.5003 A6.008 N170 X2.036 Y-.5007 Z2.2767 A12.016 R2.5417 N180 X2.87 Y-.501 Z2.2766 A18.024 R2.5416 N190 X3.704 Y-.5014 A24.032 N200 X4.538 Y-.5017 Z2.2765 A30.04 R2.5415 N210 X5.372 Y-.5 Z2.2768 A36. R2.5418 N220 X6.206 A42. N230 X7.04 A48. N240 X7.874 A54. N250 X8.708 A60. N260 X9.542 Y-.5003 A66.008 All of the geomtery is the same and all is correct for the out put I want, but this is what I get. Why is mastercam refering back to t-planes that once existed, but no longer do????

I agree John, associative geometry is exactly what I need in this situation. Looks like I am gonna have to do it all one at a time.

I cannot use scale because then all my geometry is scaled. I just want to change the diameter of the cylinder on which the points are layed out on. If i use scale, then the spacing between my points, the arcs used for T-Planes and others are all scaled down also

I have a cylinder with a diameter of 4.49 drawn with a bunch of points on the outside of it that i use for drilling. If I change my diameter to 4.3, how do I move all the entites in so that they are along with outside of cylinder. I want to move all the geometry in towards the origin by .095. If I translate, it doesn't work right and I dont want to redraw all of the entities if I dont have to. Any ideas??

welcome to the forum machine head

I like using a K-Tool Carbide Insert Endmill with through spindle coolant, I have an .870 diameter tool I have used these cutters a lot in aluminum.. On your machine I would run about all 10000 RPM and program for 100 to 125 inches a minute. Just make sure you predrill for your tool if it plunges into the material.

Jim, I do stuff that is very similiar to what you are doing. if you can email me, i can probably give you a hand at what you want to do. J.

I am going to start using a tapping head because I am tapping roughly 300 holes per part with a 10-32 tap and would like to save taps from breaking on me. What kind of tapping do you guys use? How do you like them? What do you recommend?

hey, i finally hit the 200 mark.

thanks.

I am contouring a part and I am using a ball endmill. Depending on the size of the part, it is usually either a .625 or .75 carbide ball endmill with depths of .325 to .4 inches deep in SAE1141. I just usually take .05 steps down to depth using just the ball mill. My question is do you guys reccommend roughing the contour with a regualr square or hog endmill first and then finish with the ball endmill. How do you guys do it?

Tried everything, guess it is time to go to the EDM shop. thanks for the hints guys

i tried Iskanders idea about the metal cylinder, but the thing is so small, it just bends the cylinder.

i was thinking about getting a grinder tool, kinda like one for a Dremel tool, and just grinding enough so that I could get past the crap in the hole, and then just drill with a carbide drill.

Die sink EDM is the last resort. but we would like to get it out so that we can drill the hole over size and plug and retap it. the part is a cylinder in a 4th axis, so we dont want to remove it until we have tried the other stuff.
