I am working on a Doosan DVF5000, trunnion style 5 axis machine. In MasterCAM, I've programmed with X0, Y0 as the center of the part and Z0 as the bottom locating face of the part. The intention was for the part to share the same center as the machine table and not use any dynamic offsets. However, the forgings are varying and we are using the probe to establish centerline of each part and setting G54 X and Y offsets that way. The center of each part is varying up to about .050". So, X0 Y0 in MasterCAM = Center of Part X0 Y0 at G54 on the machine = Center of Part, but the Part is not exactly on center of the rotary. If I understand G68.2 correctly... I can use G68.2 X0 Y0 Z0 I__ J__K__ and the machine will calculate the difference between where G54 X0 Y0 are and the center of rotary axes as the program moves through the different rotations? How can I verify that this is working accurately? I have a feature that I am putting in at B30.482 C0 using G68.2. It is just a hole at X2.815 Y0 at that angle. When I put the hole in, I go back to that same location using G68.2 again and probe the hole and it tells me the hole location is X2.845 Y0.0003. I can accept the Y difference, but how can I possible get a .030" difference in the X after I just put the hole in? What am I not understanding? I'm stumped... Any insight would seriously be appreciated. Thanks guys...

I'm trying to use the morph tool path to finish the hub of an impeller, the tool path looks good however when attempt to post it I get an error that says: "WARNING - INCREMENTAL C-AXIS MOTION OF -179.745 DUE TO VERTICAL TOOL, ADD RETRACT MOVE? (ADJUST TOOL PATH TO AVOID THIS)" I understand that this error comes up because when the B-axis is equal to zero there is infinite possible solutions for C, I have tried to add limits in the tool path for the B-axis so that it will never be equal to zero however this doesn't seem to solve the issue. Has anyone else had problems like this before that can share some knowledge on how to avoid this issue?

I'm machining a disk with a 5deg taper along the outside edge out 5 axis. The machine doesn't allow for any negative y values since the spindle can only reach to the center of the table. When I do a swarf cut for this outside profile, the code always seems to want to rotate the part 90 degs and work off to the side. For example the code has the spindle at around X10 and Y0, where I want the spindle at around X0 and Y10. The taper of the disk does change so currently the y values goes slightly negative. Any ideas on how to make this happen. I've tried the following: Forcing the primary axis to start at 0 Making the home location X0 Y10

I'm having a problem with the NC code for our 5-axis machine. The issue is the spindle can only reach half the table so all y values have to remain positive. I can't figure out how to fix this. Is it something in the post, the machine definition, or tool path? I've done the following to try and alleviate this issue: -Changed the y-limits in the machine definition -Changed the y-limits inside the post. Does anyone have any suggestions? Thanks for the help!

Guys, We 're getting a new Haas UMC 750 soon, like it 's on the way here.. Anyone in here have it? if so any thing I should be aware ??? lolz... Greatly Appreciated

I've used mastercam since V5.5, used it heavily from V6 to X, took another job in sales that diverted me from programming for a while, now I'm back. In the past, I used NCL for all 5 axis programming, NCL is no longer available to me so I'm going to use X7. How can I get up to speed quickly? is the Advanced multiaxis training manual good? are there any good sample files available? Where is the best place to go for 5-axis training? my local reseller recommended a local contract programmer. appreciate all the help I can get.. Russ

Mastercam VB Script for 5-Axis
Guest posted a topic in Mastercam C-Hook, NET-Hook and VBScript Development
Below is the URL for a Mastercam VB Script I wrote for debugging 5-Axis Posts. It allows the user to select a rotary configuration, pick individual individual vectors and will then produce a basic text report with the vector and angular data. Simply pressing [ESC] allows the user to exit the script at any time. If nothing else, the math in the script gives users a good idea how the angles are calculated. http://dl.dropboxuse...i-Axis_Info.vbs FWIW, I've got a series of articles on demystifying 5-axis on my Tech Blog. 5-Axis Machining Demystified- Part One http://www.mtbtech.n...d-Part-One.aspx 5-Axis Machining Demystified - Part Two http://www.mtbtech.n...d-Part-Two.aspx 5-Axis Machining Demystified - Part Three http://www.mtbtech.n...Part-Three.aspx
