Interpolate U with X, Y, and Z axis

[Zoeper]

Hi All,

I am post tweaking MPCRUG.pst for use with Avon 3000 knee type mill and mastercam V9.1

The current post outputs M1452 after rapid move if next move is a feed move and then M1453 before the next rapid move.

M1452 = Interpolate W axis with X,Y,Z axes

M1453 = Free W Axis

======================

N0188 G0 Z3.

N0190 M1452

N0192 G1 Z-3.5 F200

N0194 G3 X38.969 Y-31.477 I38.969 J-34.477

N0214 M1453

N0216 G0 Z50.

======================

W on my mill is the knee and is only a readout axis and not controlled by the controller.

My thought initially was that the purpose would be to be able to adjust knee hight to suit longer or shorter tooling with machine compensating a move of the w axis by adjusting Z offset.

The problem with that being that the compensation would only apply to feed moves and not rapid moves.

1. What would be the real purpose?

 

2. I see several lines that deals with this code in the post file. Is it safe to just disable the output of these lines?

 

3. My previous post (now lost) used to output M1000 and M2000 as standard in PSOF to turn contouring on and off and also M1401(feed and rapid override)

Is it bad to be in M1000 mode say for instance on drilling ops where you rapid between holes with no deceleration? and would you have this on or off by default?
