Mini-Plans and Alignments


---
 Share

Recommended Posts

I am measuring a cylindrical part that has a turning op and a milling op. The milling op puts holes on the OD, perpendicular to the cylinder's axis.

My program measures the entire part. The machining ops are done separately but I need to be able to check the turning op before the milling op. I'm trying to create a mini-plan to run only the turning op.

My original BA used a 3d line from 2 opposing holes done in the milling op for the Planar rotation. I removed the 3d line, and Set the BA to zero. I created a secondary alignment, using the 3d line for the planar rotation and assigned the remaining holes to this alignment.

I selected all of the turning characteristics for a mini-plan, however it still wants to measure the secondary alignment. I have verified the secondary alignment is not associated with any of the turned characteristics in the mini-plan.

I think I ran into this before but I don't recall if the issue was resolved or not.

Any ideas or suggestions? I really don't want to create 2 programs.

I'm not PCM expert, but I do use this for miniplans. Not sure if it would help?
You might have to add a little something to it. Mr. Schultze or Mr. Moberg might know?


This PCM (template) is used for a program that has several operations
(mini plans) for the same part. No external .PARA file is needed here.


LN = getRecordHead("order")

clearCAD()
dir = getActualInspectionDir()

Run=inquireList("Which operation do you wish to run?","Operation-10","Operation-20")
setRunID(Run)

endif

selectCase Run
case "Operation-10"
loadCADFile(dir+"\100XXX - Turn-Blank.sab")

// Customer Part 5.0 MM
// 100XXX Op-10
Datum_A = 7.550
Diameter_15 = 4.975
Diameter_20 = 7.520
Datum_B = 5.000

case "Operation-20"
loadCADFile(dir+"\100XXX - Grind-OD.sab")

// Customer Part 5.0 MM
// 100XXX Op-20
Datum_A = 7.475
Diameter_15 = 4.975
Diameter_20 = 7.520
Datum_B = 5.000

endSelect

Do you actually need to measure parts on this secondary alignment?

I have created programs with 7-8 machining Operations, and no secondary alignments. I simply make the Base Alignment from features cut in the first Operation, and make Mini-plans to control what runs. I also use PCM for safety, to check some sizes and positions to make sure the part is actually machined to the correct step, and to prevent them running All Characteristics or Current Selection... These programs have to be Mini-Plans only.

I really don't need the alignment for the location along the axis (Z), but I'm guessing the centerline location of these holes would be problematic.

Apparently, I overlooked 1 Milling op characteristic in the Turning Only mini-plan. DOH!
