Turning Formulas (Vc, RPM, MMR, Ra) and more

Welcome to the Machining Doctor channel! In this video, we dive deep into essential turning formulas that every machinist should know. Whether you’re a beginner, someone brushing up on skills, or an experienced machinist needing a reminder on the basics, we've got you covered! 🔍 **What You'll Learn:** - Cutting Speed (VC): Understand the relationship between spindle speed and workpiece diameter for both external and internal turning. - Spindle Speed Calculation (n): Discover how to calculate spindle speed based on desired cutting speed to stay within machine limits. - Metal Removal Rate (MRR): Learn how to measure productivity and machining power requirements effectively. - Machining Cycle Time (T): Calculate the time required for one turning pass using linear feed speed. - Surface Finish (Ra): Explore how feedrate and corner radius affect the surface quality and discover tips for improvement. 🔗 Resources: https://www.machiningdoctor.com/calculators/turning-calculators-2/ ⏲ Chapters 00:26- Cutting Speed (Vc) 01:29 - Spindle Speed (n) 02:09 - Metal Removal Rate (MRR) 02:47 - Cycle Time (T) 03:40- Surface Finish (Ra) 00:00 - Summary #Machining #Turning #MachiningDoctor
