5-Axis machine - Axis Limits

Builder
Builder

I have modified postprocessor for 5-axis machine (same as sim08_mill_5ax - heidenhein). I set axis limits for fourth axis from 0 to -139. After postproces my operation, I see rotation for A axis +45.

What is wrong?

Hi,

 

There is nothing wrog with the post. When PLANE SPATIAL is used, SPA, B and C are not necessarily equal to the angles of 4th and 5th axis on the machine. In Heidenhain control unit, the final orientation of the 45-axis is left to the machine kinematics. You can switch the orientation to the alternative angle using SEQ+ or SEQ- if you wish to tilt the 4th axis to the other side. Output nothing means SEQ+

 

Kind regards,

Sorry SEQ is missing on screen. When I set manually SEQ to minus, simulation works.

I want to method, when is A axis rotate to operator (if possible), part is better vissible for operator.

Hi,

 

There is a point is post processor that decides SEQ+ or SEQ- should be output. Find that command and change it to output allways SEQ-. Your machine will do the rest.
