Does "filtering" reduce cycle times ? Or does it just make a shorter NC code? I have found that doing EVERTHING I can in 2D and then only useing 3D tool path where necessry is the most efficiant,would you agree? | |

if your machine ever seems to stall out while spoon feeding, then filtering will make a big difference, fadal and hass do come with decent controls compared to a stock fanuc om type control. but a fanuc 15m or better with 250 or 500 line look ahead pretty much smokes most machines throughput. filtering also makes 3d movement smoother for the machine, if a arc is broken up into hundreds of parts the machine has to calculate start and end and tengency of the following moves, including acceration and deceration for each line segment. filtering will also fit an arc into a spline within a predetermined tolerance. if your part is not critical accuracy wihich most 3d project dont seem to be (.0001) i know moldmakers get very picky as they should. bottom line, filtering makes machines faster, parts lightly smoother and use much less memory, | |
