Engineering & Safety Notice
CNC machining is inherently hazardous. All speeds, feeds, RPM values, cutting parameters and cycle results generated by our calculators or shown in our articles are estimates based on general formulas. They must always be verified against your specific machine capabilities, tooling manufacturer data, workpiece material and shop conditions before being used in actual production. Incorrect parameters can cause tool breakage, machine damage or serious personal injury.
