make sure it's not defined as a taper mill

Its aggravating, but MC considers taper mills and changer mills 2 different types of tool

each with their own cpabilities

Where would I go to check that out? I've been through the tool parameters page, and didn't see anything like that.

I created a 30degree chamfer tool in Novo, which is software used by Kennemetal. Once I "built" the tool in Novo, I imported it into Mastercam. and now I can't get it to work. It's telling me that only chamfer tools are supported in model chamfer...but it is a chamfer tool. Any ideas?

What operation are you using please, also using which version of mastercam and what are you trying to accomplish, adding tool wear G41 G42 perhaps?

Sorry, pocket milling, version 2019, and yes, attempting to add wear on G41

Can someone explain why cutter comp is only an option on finish pass in MasterCAM?

Look at the backplot details (X, Y, Z coordinates as you step along) to see what the toolpath is doing.

You are using the multiple passes option within the toolpath?

 

The tool is following the boundaries set by the geometry. It just goes around, with no stepovers. And yes, I'm using the multiple passes option within the toolpath. I know these machines are capable of doing what I want, I'm just not sure how to get it to do it. lol

Howdy, Lazarusman here again. I'm trying to program a 2D chamfer that makes multiple stepover passes, but I can't seem to figure out how to do that. Every time I run it in simulation, it doesn't stepover. Any advice would be greatly appreciated.

Thank you,

Lazarusman

I believe I just found my issue.  While in roughing parameters I had my roughing passes set to 15.  Not realizing that It would run the same level 15 times, not step 15 times.  Sorry, it has been a long day and this job was just tasked to me saying "see what you can do".  It is exciting because this has been the most difficult multi axis request so far.

 

Thank you have a great weekend

What was your solution?

Is there any way to number operations that use the same tool?

Forgive me if this topic has already been discussed, but I couldn't find specifically what I wanted. So I'm trying to figure out how to number more than just tool change lines....maybe just some lines, maybe all lines, I don't know. I googled it first, and came up empty. Any help would be appreciated.

I'm running a 7 or 8 year old Akira-Seki vertical mill, with taps made by Kennametal... 1/4-20, 3/8-16. Broke them both right off. I ran them at 196rpm, with 14. threads per inch. My machine uses an E value for TPI...which is new to me. I'd love to find some resource material for spindle speed, and TPI, to cross reference my programs. The speeds and feeds that MasterCAM is putting out, for the taps at least, seem quite high.

Thanks again for y'all's imput.

I don't know if this topic has already been covered. I did a search, and didn't find anything. What I'm looking for is some information on spindle speed, and threads per inch for rigid tapping. My mastercam software keeps putting in insanely high spindle speeds. and aggressive threads per inch values in my programs, and I keep breaking taps. Any help would be appreciated.

Thanks

Contact your reseller whom provided you with the demo.

I already talked to him. He didn't have any answers.

Because I'm actually making parts. My company wanted a demo version of MasterCAM to see if they wanted to use it. They wouldn't just take my word for it lol. Problem is, MasterCAM is outputting code that isn't actually working with my machine. I can't tap at all, and my speeds and feeds on everything else is not quite right. It makes it harder to make the claim that this software is far superior to what they have, currently. FeatureCAM...and it sucks.

MasterCAM sets my speeds and feeds, but due to having only a demo version, my speeds and feeds aren't quite right. Is there a way to adjust them in the software, manually?

THANK YOU

I'm trying to create a cylindrical raised boss on my part. For the life of me, I cannot figure out how to do this. In the simulations, it's always trying to mill the inside of the boss, therefore creating a pocket, and not the outside diameter. Any suggestions?

It's not recognizing it as a tapping cycle, so no, it isn't reversing at the bottom. (Raised Z 3 inches for dry run). They had been using a software called featureCAM... which sucks, but at least it'll tap. I compared the two programs, and the one that works, has no G94 or G95, it uses a G84 tapping cycle, with an E code. I assume the E code has something to do with feed rate in and out of the hole. I don't know how to calculate this variable, manually. Otherwise I'd just do it myself until I can get the full version of masterCAM.

Thanks again for your advice. 

So. I have new information. Apparently my machines use a code I've never seen before. It's an E. followed by a number. I assume it has something to do with plunge rate, and retract rate as it applies to the tap cycle. Here is a sample.

N90 T8 M06
N95 G43 H8 Z1.5
N100 G00 G54 X-1.655 Y0. S220 M03
N105 G90 Z1.0
N110 M08
N115 G84 G98 Z-1.4149 R0.1 E16.0
N120 G80
N125 X1.655
N130 G84 G98 Z-1.4149 R0.1 E16.0
N135 G80
N140 G91 G28 Z0 M09
N145 G40 G49 G80
N150 M01
 

As you can see, there's no G94, but there's that strange E code.

What do ya'll think?

My machines use a Mitsubishi controller, which is non FANUC, and I'm not super familiar with its functions. As I have stated, I'm still relatively new to machining, and programming. I didn't know there was more than one tapping method used in CNC machines. I'm completely unfamiliar with lathes. (Haven't had those classes in my trade school, yet) I programmed the tap cycle, and Mastercam threw in a G20, and two G94s, per tap cycle. Also, I'm using a demo version of Mastercam, and one of my instructors told me that the problem is most likely because the demo version of Mastercam doesn't have my machine specifications loaded into it.

Thanks for all your help.

It's a 7 year old Akira-Seiki Performa Jr.

I'm still new to programming, and I've only been machining for 2 years. When I post processed my program, the tap cycles don't act like tap cycles. They act like drills. I'm confused.

Need help. I programmed a drill tapping cycle, and it put in a G94. Connect me if I'm wrong, but cnc machines are preset to in/min. I got an alarm after attempting to run the program. It stopped on the G94 line. Kinda confused. 

Let me start over. I am a MasterCAM beginner. I've had one 8 week course at my trade school, in how to use MasterCAM. I am in no way, an expert. I need to figure this out quickly. I'm not finding videos that are helpful to me. I have very little experience running MasterCAM, and some of these changes are confusing. I was trying to drill a hole, and mill an open slot, starting in that hole, but it won't let me select the center point of the arch that makes up the inside end of the milled slot on my geometry. I have to import files from solidworks, to get the geometry. Should I just redraw it in MasterCAM? I thought I could use the existing geometry from solidworks, but it isn't working out that way.

Thanks in advance

I took a MasterCAM 1 course, at my trade school, last year, and now I'm about to start a new job programming. This version has some changes, that I don't understand. Is there a source that I can go to and study up on them, watch videos, or something?
