MISC Values Help

Recommended Posts

I could use a nudge in the right direction here. I am trying to use long tools with a Mori NMV5000 and a tall part. Long story short I need it to retract to a safe distance when rotating. I have tried reference points with little success, And all though forcing tool changes gets it dont seems like a waste of time.  I know I can do something in the Misc Values and reals but the post does not give me a clear description of how to set them up....

any help on how to use these values would be great. Thank you

It souds like you are using a Generic Fanux 5X, possibly dealer modifed

mr7, mr8, mr9

do not use these !!!

this are used to change the output to reflect a the pivot distance form Mastercam zero to the pivot point of your machine

this field must be set to 1 for it to work

shft_misc_r  : 0     #Read the axis shifts from the misc. reals

incorrect use of these 3 mr's will result in shifted X Y and Z output 

 

Try this 

set your desired safe retract value in mr6

# mr6 - Absolute Safe height in Z for unwinds and toolchanges
#       (limits must be enabled and mi8, see 'use_stck_typ')
#       (set the limits to zero to ignore limits and use this safe height)
#       0 = Off

 

Then you can control it with mi7 and mi8

# mi7 - Enable retract to and from linear limits.  Disable for
#       internal work to prevent part collisions.
#        0 = Disable, 1 = Enable
#
# mi8 - Safe retract/approach at toolchange.
#       The tool retracts/approachs to limits from last path to current
#       path or after/before a toolchange
#       (limits must be enabled, see 'use_stck_typ')
#        0 = Disable all toolchange retract/approach
#        1 = Enable null toolchange retract/approach only
#        2 = Enable toolchange retract/approach only
#        3 = Enable both toolchange retract/approach
#        4 = Enable retract/approach between 5 axis chains (cutpos) in
#            toolpath or sign 1 to 3 negative with toolchange options

 

This may or may not work depending on how your post as been modified

You should be very careful until you are sure this is working properly and you understand

how this affects your output

Hi Pete,

What machine is this for (Kinematic arrangement)?

MR6 - absolute Z safe height, is meant to be used on Trunnion style machines, since clearance on a Trunnion can be obtained by retracting the spindle.

For MI7 and MI8 to work properly, you must enable the "linear limits" inside the Post. 

The "linear limits" basically has two different modes:

1. Linear Limits are defined as a cube around the outside of your part. They can be set inside the Post itself (machine limits), by setting the min/max XYZ travel variables.

2. Limits can be set based on the Stock Setup "stock block" values (only works with a rectangular block by default (cylinder is not supported by default). When using this method, there is an "incremental retract vector distance" variable that is set inside the Post, which is the distance the tool tip will retract/approach from, past the stock.

Linear Limits must be enabled for the MI7, MI8, and MR6 to work. (use_stk_typ = 1, or, use_stk_typ = 2)

I typically use "2", and a incremental clearance value of 3".

Remember that MI7 disables any/all retract and approach motion. (Turns off MI8 or MR6)

MI8 and MR6 are essentially "mutually exclusive". Use one, or the other, but not both. (When using MR6 on a Trunnion, set MI8 to '0'. Only use MI8 on a Gantry, never MR6.)
