Understanting how tow kalkulate feed rates and speeds os essential for CNC machinists to ensures empiticient and morating reastiing.

Calculating Spindle Speed (RPM)

Ini adalah kalkulated based dan diametrar of cutting tool and surface fastded.

FLT: 0 = RPM = (Surface Speedy x12) / (413) S011: FLT: 1 HS3; ASAP 3;

Dimana:

  • Surface Speed: in feata per minute (ft / min)
  • Didemorr: in inches (in)

Calculating Feed Rate (IPM)

Ini adalah Inches Per Minte (IPM), yang menentukan bagaimana cara kerjanya.

FLT: 0 = Feed Rate = Chip Loud × Number of Flutes × RPM 1; FLT: 1 = 3; ASA3;

Dimana:

  • Chip Load.tthepostpostof materialremoved per tooth per revolution, in inches
  • Number of Flutes: the number of cuttangg edges on the tool

Praktek Application

By combing these formula, CNC machinists can determinasi optiml spinl speeds and fed rates for diferens tc materials and tools. Adjustments arn ocite basey on machine capabillees and specitable proctic retempt rementations.
