5-axis sculpted aluminum: stepped adaptive roughing to mirror-finish on ENCY CAM

JHC-KOVO shared a follow-up from a five-axis aluminum job: a sculpted freeform component with an inner circular pocket, taken from stepped adaptive roughing all the way to the mirror-finished top surface on the second operation. The Czech shop programs and posts every job through ENCY CAM.

Adaptive roughing of the inner pocket
The pocket is opened up with a stepped adaptive strategy (stupňovité hrubování vnitřní kapsy) — constant chip-load trochoidal passes that peel material off the walls in progressive step-downs while keeping the tool engaged safely. This is the high-material-removal phase that clears the inside cavity ahead of the finishing runs.

Second-operation finishing on 5-axis
For the second setup, the workpiece is moved onto the trunnion (A-axis tilt + C-axis rotary visible in the enclosure), where the sweeping outer contours and the boss around the pocket are finished with a small ball-nose endmill at a tight stepover. Flood coolant, aluminum chips on the enclosure walls, and a specular mirror finish on the final part are the tell-tales of a clean high-speed finishing pass on wrought aluminum.
