5TH AXIS DRILL 4 X 4 NO RETRACT_2019

CAD

I drew a line through the center of the holes top and bottom. I then extended the line .1 in both directions. This will act as our lead in and lead out to get the tool into the holes and out of the holes without a rapid move, but allow a rapid move between both holes to not have wasted time feeding down one line. I could have not extended the lines, but experience tells me this is needed to not crash the tool and tear something up.

CAM

I called up a basic 3 Axis Vertical Milling machine. I then called up picked Contour as my toolpath in the 2D area under the toolpath ribbon. I picked the 2 chains I drew in the center of the 1st hole which are the 2 lines. I went and grabbed a 1" inch endmill and defined it to to the machining required. I grabbed a HSKA-100 holder since I always define a holder for anything I do in Mastercam. Any programmer not defining holders in this day and age is lazy IMHO. On the Cut parameters page I turned off Comp. I changed the contour type to 3D.

I used no other settings. No Depth of Cuts, lead in/out, break through, multi passes, tabs.

In the linking parameters I unchecked clearance and retract. I set feed plane, top of stock and depth to zero. I made sure Feed Plane and Top of Stock were incremental. Depth will grey out on a 3D contour this is normal.

I then expanded the Linking parameter hitting the plus button to show Home / Ref Points. I then used 2.5 for Z absolute only for the approach and retract.

I hit the green button and now I have a toolpath doing what you asked.

This is not a drilling cycle. This is how I wrote code by hand to do this same exact thing in 1988. One of the 1st programs I wrote for a shop when I was in trade school. We didn't have NC machines or CNC machines so I wrote programs for local shops for the teacher to get experience. I wrote it was one move and it was a 12" x 12" pieces of Steel tubing with a 1" wall. The owner called the teacher screaming about the .5 ipm feed rate for 10" through the tubing. We were drilling a 4-1/2 holes with a spade bit on a big HBM. It was an easy fix, but I gave them exactly what they asked for originally.

Thanks, I didn't pay attention to the date of the post I think it's older but, it helped

Got a good one for you. Make a 1/2 endmill work like a chamfer mill. Seems they did not pay attention to the tool list, program note, or the fact that it scrapped the part. Oh the the fun begins about how stupid a programmer I am and how I make bad programs and everyone loves to tell the owner I made a mistake, yet when someone else makes one they never fess up. I pretty much let it be known today I got big shoulders and if I were let go because the perception is I can not do my job because of others people mistakes I can find me a job tomorrow can you? No comments imagine that. graemlins/cuckoo.gifgraemlins/cuckoo.gifgraemlins/bonk.gifgraemlins/bonk.gifgraemlins/banghead.gifgraemlins/banghead.gifgraemlins/headscratch.gifgraemlins/headscratch.gif

I'm with you Brother.  Although it sounds like you handle it better than me.  I usually decline to comment rather than get into a back and forth.  Mainly because it seems like an operator can xxxx on the floor and not get into any real trouble, at least over here in Wisconsin.

It usually gnaws at me so it makes me think,  Dude! I started way WAY back on the floor.  I've done you're job as a button pusher/operator (depending on the individual when a situation happens)  Now, as a manufacturing engineer my job involves CIP's, Programming, Fixture Design, Procurement, etc.   You're over here acting like you're a Damn Genius and the reason this tool went through the part and into the table is because I did something.  NOooo! it had nothing to do with you not touching off a tool correctly.

Here is what Tim Markoski shared years ago.

Tim's Port Tool Files

Thank you SO! much Tim Markoski,  I just downloaded, haven't checked them out yet but, I trust they are legit.

The files will really help.

Thank you so much for your response!  I get somethings together and post asap.  It's another busy day at the salt mines.

Would anyone know a resource, pay or free at this point I will feel blessed to be able to find something that could get me to understand how to judge and decide which of the many 2 or 3 D strategies MS has available is the one I should select.  At least I would be love to be able to narrow it down to 1 or 2.  

Also I like to find instructions more specific or to the point.  Like a step by step break down of approaching programming of a solid model.  I have watched  the "my mastercam"  courses, "mastercam core" , "2D mill" and although nicely done it is very broad.

You can look at the file I have attached.  I was asked to mill a groove on the inside of a hole clocked at 3 and what you see is the best I could do.  Darn pathetic I know BUT, I will do whatever I need to in order to get so I understand this.

PLEASE any help sent and "your a good kind person someday people will wright songs about" that's what i'll say to anyone and everyone whether they care to listen or not 

keyseat cutter for groove 24246P32.mcam

I wanted to build a solid model tooling library and start using them to verify my toolpaths.  From what I hear it's the greatest thing since... yes, sliced bread.  

Shortly after I began the process I got frustrated.  I must be doing something wrong.  I ended up following along with a youtube 

After going through the tuts import process I can't believe it's correct although the results are better that what i get when I pull the tool solid moder in.

 This is the result the tut on youtube showed after import.  

I downloaded a GTC package, a DXF, and a 3d step from sandviks site and got THIS.  This is what should be the model for a keyseat/slot mill cutter.  I would expect the solid model to show the inserts or some sort of detail.  Please, tell me where I went wrong and what I can do to achieve a better representation or if this is the best case scenario please let me know I drank the kool-Aid and yes, this is the big let down.
