Does anyone know a good way to machine sheave grooves? I need to machine a repair part and I think the multiple grooves confuse MasterCam. I am using MasterCamX 3.

Hello again, Just a few other things. This is a flatbed front turret lathe. In the General Machine Parameters page, for this machine which default cplane should I be using? And in the window "Update wcs using" None Top Lathe Z=World Z As it stands now when I look at the Mastercam screen, in the lower left corner is a set of coordinates with a x+ at the top of and a Z- on the right side. Is this the way it should look? Thanks! Tim

Thanks! I contacted Milltronics about this. They suggested I manualy edit the program in the beginning with a line PB81=2 This turns off the trig help at the controller. Then a line just before the M30 PB81=0 to turn it back on. I,ll let you know how I make out! Tim

Hi, So you know, I'm self taught on Mastercam X lathe, so when you say "Look at the right offset" I'm not really sure where to look! Given that, where do I find the three positions you refer to? Machine Position, Work Offset Position, and Shift Position. This is the program I am getting when I post. In this I have disabled all Lead in/Lead out moves, and I am using "Home Position from Machine". In the Default Home Position Box I have X 0.0 Y -7.50 Z 0.0 My Machine Axis Combination is set to Left/Lower. In the Machine Configuration Box I have disabled the "Lathe Lower Turret Y axis button. That is why I am no longer getting a "Y" dimension in the code I suspect. % O0000 (PROGRAM NAME - STUFFING BOX) (DATE=DD-MM-YY - 21-07-14 TIME=HH:MM - 07:11) (MCX FILE - M:\BLDG20\MASTERCAM\NC\ML22 FILES\T.MCX) (NC FILE - M:\BLDG20\MASTERCAM\NC\ML22\STUFFING BOX.NC) (MATERIAL - STEEL INCH - 1030 - 200 BHN) N100 G20 (TOOL - 1 OFFSET - 1) (STANDARD ROUGHER INSERT - WNMG-432-MF2/EDP #27769) ( ROUGH FACE ) N110 G0 X15.

T0700 N1220 M05 N1230 M30 % As you can see, the code sends the tool to X15.0 Z 0.0 just like I want, however in actuality at the end of every operation the tools back off to a position that varies from X 3.4941 to X 4.4752 and Z 2.4219 to Z 2.9020. It's as if there is an intermediate position the tools go to before they go to X 15.0 Z0.0. Added to that, the actual "Tool Change Position" is X 17.1004 Z 2.9020. This also sends the cross slide towards the tailstock. Is it possible that when Mastercam cancels the tool offset with the line "T0100", that this is what the intermediate step is? Thanks again! Your input thus far has been very helpful! Tim

Thank you! I have a few more questions though. 1) Where do I set up the default home position for all tools? 2) This lathe is a flatbed, with a front mounted tool changer. If I define the home pos. in the Lathe tool setup box, I have to put a minus sign in front of the X 7.5 value in order for the Toolpath Parameters page to show a positive number in the "Home Position" box. Do I need to change something in the machine axis page to correct this? 3) The post is outputting N110 G0 X15. Y 0. Z 0. Why the Y 0.? This is only a two axis machine, and why does the post double the X value from 7.5 to 15.0? 4) When I run the program and an M01 prior to a toolchange is read, the machine moves to a position about Z 2.9 and X at a diameter of about 3.00 although my screen shows X7.5 Z 0.0? 5) At the machine I just gave it an MDI G0 Z15.0 and it moved to the correct location. The screen changed to X15.0 Z 2.8980 I know this is a lot. I really appreciate your help! Tim

Hello, I am running a Milltronics ML22 lathe with a Centurian 7 controll. I am using Mastercam X3 with a MPFLAN post proccessor. I need to use the tailstock most of the time. The issue is that the code that I get from MPFLAN sends the tool post to the machine home I believe. Which is beyond the tailstock. The code I see is G28 U0. V0. W0. M05 What I think I need to see is G0 X15.0 Z0.0 M05 What do I need to edit and where is it located in MPFLAN? Thanks! Tim

Gentlemen, I am using MastercamX to program a shaft with a face relief. I am trying to use a SECO MVTNR-16-3D tool holder. When I bring it in from the General Turning Holders Tab , the 117.5 Degree side clearance angle is only 5 Degrees. Is there a way to modify these tools so that they Show correctly? By the way, all of your help so far has been great and greatly appreciated! Tim

Got it! It took me a while to understand that you have to copy the cross section geometry and then individually chain them. Thanks for the help! Tim

Thanks for the file! However my MastercamX is too old to open it! Tim

I understand that part, but how do you get the program to repeat the finish face and the part off opperations? The work offset would change by the width of the parting tool. Tim

I need to make flat washers and want to drill, bore rough and finish I.D. and O.D. Then part off several parts before having to drill and bore again. Is there a way to do this in MasterCamX? Thanks! Tim
