Thank you all for the replys, very helpful.

I understand how to figure out speeds and feeds. But when you cut a finish pass of say .01 your feed should be alot faster to maintain the chip load. My question is what is the math formula to calculate chip thinning. Thanks is advance.

One machine is format 1 and the other is format 2. The one thats format 2 is the one with all the problems with the post. The post works good with the one with format 1. Does anyone have any opions which format is better to run. The reason were thinking about changing to all format 2 is we have haas machines as well, and if we go to format 2 there pretty close to each other. But from my experence format 1 is alot easier. Just wondering if any one had preference and why? Thanks again

I work in lapeer Michigan. So If I have G54 in the controller set, and my program shows E54 it will work? I will try that and see if it works. Thanks

Im editing my fadal post, and could some one point me in the right direction. What I am trying to do is make it so when I post a program it doesnt use the "E1" values. Right now I just erase them and then add my G54 values instead. I am using V9. If someone could just tell me what area of the post to change this it would be much appreciated. Thank you in advance.

thank you all for the help

I know my fadal if I use a G8 before my code it smooths thing right out. Does a Haas use that G code?

I just started using a Haas vf2 vmc. My question is there a part timer on the display to show how long a part takes to run. I looked in the menus but I cant find it. Just wondering if the haas has that option. I know the Fadals I have ran int he past you got to turn that option on. Thanks in advance for the help.

Thank you all for the info. much appreciated.

Could some one please give some suggestion on a speed and feeds (sfm) and chip load per tooth on a two fluted endmill for machining acrylic. I have never machined acrylic before, so does it chip real easy during machining? Thanks in advance for the input.

Thank you both for the help. very much appreciated.

I just wanted to say I am not asking for a post Just what area of the post to edit to take care of this. Thanks

First thing is im using version 9. I am editing or should I say trying to edit the mpfadal2 post. What I am trying to do is take the speed code and the spindle code out every time I use the tapping cycle. I finally got it to post a G84.1 instead of a G84. The problem is im using a format 1 but my the mpfada2 post is set up for a format 2. I want line N100 not to post the seed and spindle direction. Thanks for the help in advance.

Can some one help me understand when I need to unroll something when I program my 4th axis. From what I understand is you only need to unroll when your programming from a solid part. But you dont need to when you use a flat pattern that you substitute your y axis. Am I on the right track with the unroll option? Thanks for the help in advance.

Thanks alot John your help is much apreciated as everyone else is.

The slot is .790 long in the X direction. Im starting at X0.0 A0 and moving to X.79 A95.0, which seems to give me the 30 degrees angle when I lay it in a vblock and check it in the shadow graph. The customer wont let us show the part print to any one other wise I would make this alot clearer and post it. The dia. of the part is .551 with the slot being .06 dp. and .06 wide. The shaft has 11 slot around the dia. which comes out to about 32.7272 degree turn in the a axis for each slot to start. So what im doing is a helix slot the is at a 30 degree angle from the center line but the helix angle is about 95 degree worth of turn in the a axis. Im sorry is was gone for a few days but I really aprreciate you guys help.

I hope I can explain this clear enough, so hear I go. I am machining a slot in round stock using the forth axis. The slot is .790 long and the forth axis needs to turn so it is 30 degrees. I found if I do a X.79A95.0 it does it to 30 degrees. I did this by trial and error, what im wondering is there a math formula that tells me how much I need to turn the 4th axis to get the 30 degree angle at a given X distence. I hope I explained this good enough. Thanks in advance for the help.

Thank you for you help, that fixed my problem.

I will try canceling the drill cycle and see if that works. thanks a ton for the help. by the way i just order a 4th axis training video to do this in mastercam as you can see, I pasted this program togehter.

forgot to mention I only pasted part of the program in the post. Im sure most people would know that by looking at the post above. I just posted enough to see where the problem might be.

my question is my program drills the first hole at A-0 then rotates the a axis 6 degrees and drills the hole. But then it redrills the hole again before it rotates the a axis. then it rotates anther six degrees. Cant seem to figure out why it double drills every hole.

Hello everyone, I was just curious about hidalgo comments about form taps. I was always under the impression that rolled thread where stronger than cut thread. I thought I read that in the machinist handbook. Im just wondering if I understood this wrong. Im not saying your wrong. I just would like to know which is stronger. The reason I would like to know is I am about to do some military work, and I sure would like to find out now, not later. Thank you all for your help.

Thank you very much.

Terry, could you send me that email? I could learn something from this also. Im running mc9. Thank you very much.

Thank you for the help. much appreciated
