Been machineing for about 10 years but relatively new to cast machineing. Lookin for aome suggestions on the optimal roughing toolpath for machineing a cast steel mold with approximately.250 on all surfaces. Part has shape but is relatively shallow in most places. Surface finish contour and waterline run into too much stock at beginning and in shallow areas. Unfortunately machines top speed is only 6000 so opti-rough is not an option. So far the only thing i have found that works is multiple surface finis contours at different atock to leave depths or a surface rough pocket that starts at highest point and cuts alot of air for the first half of the program. Any suggestions would be appreciated.

relatively new to machineing cast steel. Going by the numbers givin to me it is about 170 -229 HBW. That puts it under the carbon steel category of most of the mitsubishi tools im running.  550 sfm and .05 fpt is whats recomended but im blowing incerts even at .03 doc. Any recomendations would be appreciated.
