Differenciate toolpath process as per XY & Z thickness.

Hi ! All,

I was working with a macro and I stuck at some place.

Thanks to who help me figuring out the issue..

My macro is intended to diffrenciate the toolpath as per (Radial and Axial thickness).

Macro I use is .......

STRING $type = ' ' REAL $type_thk = 0 REAL $type_axial_thk = 0 REAL $type_radial_thk = 0 FOREACH tp IN FOLDER (active_folder()) { ACTIVATE TOOLPATH $tp.name $type_thk = $tp.Thickness $type_axial_thk = $tp.AxialThickness if ($UseAxialThickness == '1' AND $type_thk > 0.1 AND $type_axial_thk = 0) { $type = "-Rest" } elseif ($UseAxialThickness == '1' AND $type_thk < 0.0) { $type = "-Finish" } elseif ($UseAxialThickness == '1' AND $type_thk >= 0.1) { $type = "-Bottom-face" } elseif ($UseAxialThickness == '1' AND $type_thk < 0.06) { $type = "-Semi" } elseif ($UseAxialThickness == '1' AND $type_thk > 0.1) { $type = "-Rough" } elseif ($UseThickness == '0' AND $type_thk < 0.1) { $type = "-RRR" } else { $type = "-!!!_Process-Unknown" }

Thank you !

It looks like you forgot the double equals sign.

You have $type_axial_thk = 0. It should be $type_axial_thk == 0.

When assigning a value use 1 =. When comparing or checking a value, use 2 =.

HI !

Thanks for replying.

No, It's not working like that.

My intention of using this macro is ..

When Radial thickness is >0.2 (AND) Axial thickness is >0.1 -- ROUGH

When Radial thickness is >0.22 (AND) Axial thickness is =0.0 -- FLOORING

When Radial thickness is <0.18 (AND) Axial thickness is >0.1 -- REST

When Radial thickness is >0.1 (AND) Axial thickness is >0.1 -- SEMI

When Radial thickness is >0.0 (AND) Axial thickness is >0.0 -- FINISH

When Radial thickness is <0.0 (AND) Axial thickness is =0.0 -- BEARING FIN

I have tried several tricks without any success.

Code is attached.

Hi,

Try it like this this, i've contained each check in it's own brackets.....

$type_thk = $tp.Thickness
$type_axial_thk = $tp.AxialThickness
if ($UseAxialThickness == '1') AND ($type_thk > 0.08) AND ($type_axial_thk < 0.06) {
$type = "REST"
} elseif ($UseAxialThickness == '1') AND ($type_thk < 0.01) AND ($type_axial_thk < 0.01) {
$type = "FINISH"
} elseif ($UseAxialThickness == '1') AND ($type_thk < 0.2) AND ($type_axial_thk < 0.0) {
$type = "FLOORING"
} elseif ($UseAxialThickness == '1') AND ($type_thk > 0.05) AND ($type_axial_thk > 0.05) {
$type = "SEMI"
} elseif ($UseAxialThickness == '0') AND ($type_thk > 0.1) {
$type = "ROUGH"
} elseif ($UseThickness == '0') AND ($type_thk < 0.1) {
$type = "RRR"

It appears to me that you need to add more conditional statements to assign the correct 'type'. Currently, If you have a toolpath that uses 0.21 radial thickness and 0.11 axial thickness, it could be assigned both 'ROUGH' and 'FINISH' types with the logic in your post above. I'm not sure how you actually want to assign the 'types', so I can't finish the logic for you.

Remember, you can check the same parameter multiple times in the same elseif line:

elseif ($UseAxialThickness == '1' AND $type_thk <= 0.2 AND $type_thk >= 0 AND $type_axial_thk <= 0.0) { $type = "FLOORING"

And I prefer to use >= & <= for checking multiple conditions. This prevents you from assigning the wrong value when the value you are checking equals the value you are checking against.

The most important thing when writing a macro with a long if/elseif chain, is to make sure you understand your conditions and to make sure it is not possible to assign two different values to the same condition.
