Increase accuracy of simulation duration by invoking externally calculated rather than internally estimated layer times
*TDWL a1
a1: a*8192: filename of the JSON file containing toolpath timing data
The *TDWL card enables a more accurate process simulation by using a generated additive-toolpath times for each printed layer. This brings the simulation closer to the actual process, in particular with regards to cooldown. The JSON file required for *TDWL can be automatically generated in Autodesk Fusion while setting up an additive process simulation.
Here is a short example of a JSON file for *TDWL:
{
"schema": "com.autodesk.pan.sim-toolpath-time-1.0",
"toolpath_time":
{
"z" : [ 0, 0.04 , 0.08 , 0.12 , 0.16 , 0.2 ],
"time": [20, 21.8932125, 21.8928375, 21.8922375, 21.8918875, 21.893275]
}
}
A realistic example would have many more layers. The units are millimeters for Z and seconds for time. The sizes of both arrays must be the same and Z coordinates must be listed in ascending order. Time values are the durations of each layer, including both deposition and recoating.
