• Iterate on the design based on feedback from engineering teams, manufacturing experts, and end-users to
optimize functionality, manufacturability, and cost-effectiveness.

Blank Preparation:
• Procure raw material in the form of bars, sheets, or blocks, depending on the chosen material and the size of
the drawing tool.

• Use cutting tools such as saws, shears, or water jets to cut the raw material into blanks of the appropriate size
and shape for machining.
• Perform preliminary surface preparation techniques such as grinding or milling to remove any surface
imperfections or contaminants that could affect machining accuracy.
• Anneal or normalize the blank material to relieve internal stresses and improve machinability, if necessary,
before proceeding to machining operations.

Rough Machining:
• Set up the blank material on CNC milling machines, lathes, or machining centers using precision fixtures and
clamping devices.
• Roughly shape the blank to approximate dimensions using coarse cutting tools such as end mills, drills, or
turning tools.
• Employ high-speed machining techniques and adaptive toolpaths to efficiently remove excess material while
minimizing tool wear and cycle time.

• Monitor machining parameters such as cutting speed, feed rate, and depth of cut to optimize material removal
rates and prevent tool breakage or workpiece deformation.
