The 2 axis post processor

HelpCadfil Help contents Home

The 2 axis system is best suited to the winding of cylinders though can be used for other components with care. The operation of the 2 axis post processor is exactly as for the 3 and 4 axis systems, with the following exceptions:

i) Only the mandrel rotation and carriage machine axes are used.

ii) The user is required to enter an additional clearance parameter.

iii) There are limitations on the winding of low angles.

The 2 axis post processor (where supplied) can be executed by selection at the appropriate post-processor menu option. The system is intended primarily for use with a payout 'eye'. The eye travels along a line parallel to the machine 'X' axis in the 'Z=0' plane. After the entry of the Payout extension, the user is requested to enter a payout clearance with the prompt:


The value in the square brackets is the default value, and can be accepted by hitting OK with no other input. Another value can be entered if required.

This clearance must be supplied in the mandrel units, and is added to the maximum mandrel radius for the particular mandrel used. This then fixes the distance from the winding axis of the line the payout eye moves on.

Because there is no cross-feed' travel, if the winding program has low (zero is axial) winding angles, then the machine carriage travel to achieve the desired position will be large. This may be greater than the machine travel available, or may give poor fibre control due the large distance between the payout eye and the contact point on the mandrel. The end-overshoot effect can be reduced by decreasing the clearance, but the user must exercise caution when using low clearances as a clash with the mandrel could occur if measurements have not been made accurately.
