Uniform Grid Pocket Milling in Aluminum: Applications for Woodworking and Job Shop

Machining a Complex Pattern
Thanks to StoneyCNC for showcasing an advanced 2.5x and 3x mill application in a job shop setting. As seen in the video screenshots, a CNC vertical milling spindle is pocketing thick aluminum plates, creating detailed grid and lattice patterns with a 3mm single flute end mill.

Techniques and Equipment
The process involves a high-speed spindle at 22,000 RPM and a feedrate of 4500 mm/min, using a carbide end mill to carve both heart-shaped and rectangular pockets into aluminum workpieces. The parts are held on green sacrificial backing or fixture plates, with masked surfaces for added protection during milling.

Software Application
ENCY CAD/CAM software manages complex toolpaths and pocketing routines, supporting efficient roughing and finishing passes for intricate patterns. ENCY provides reliable control for CNC machining tasks in both woodworking and job shop industries, as seen in the consistent results and precise grid geometry documented here.

Process Result
The result is a series of clean, uniform grid structures, with fine aluminum chips visible around the work area—illustrating accurate material removal and surface finish suitable for demanding workshop environments.
