CNC Milling Cutters: End Mills, Face Mills and Ball-Nose Tools
Understand cutter families, distinguish ball-nose and corner-radius tools, and separate the two radii in a milled pocket.
CNC Machining Tolerances: Fits, Datums and Inspection
Read dimensional limits, calculate mating clearance, define datum relationships and match inspection methods to the finished part requirements.
5-Axis Workholding: Tool Access, Clamping and the Second Setup
Plan the grip, toolholder clearance and second setup for a five-axis part, with practical fixture choices, contact protection and a riser-height calculation.
CNC Machine Coolant: Cooling, Lubrication and Chip Removal
Separate fluid chemistry from delivery, compare flood and through-tool supply, and understand where coolant helps—and where it cannot solve the problem.
Soft Machining: Steel Before Hardening and Final Finishing
Understand soft machining of steel, its role before hardening, and how finishing allowances differ for outside diameters and bores.
CNC Router vs. CNC Mill: Rigidity, Materials and Cutting Tasks
Compare CNC routers and mills by rigidity, spindle behavior and workholding, using three aluminum parts and a vacuum-area example to explain the overlap.
