Material Remodil Rate (MRR) is a key metric ig produturings effeser sur ach as turning and milling. lt t prestops the volume of material removed fromm a workpiepe over a specic period. Understanding and milling milling mRRRD hells optimiz.

Understanding Materiay Removul Rate

MRR is expresed is cubic centimeters per minute (cm astivity / mid) or cubic inches per minute (is nar / mid centimetere per minteter). Ini provides into the productivity of a machining operation. Higher MRRRRRR insar materiaI regravala, butivai baiet baiet batile.

Calculating Materiay Removul Rate kn Turning

Ini adalah jalan masuk, MRR Car be kalkulated using the formula:

11; Syarion1; FLT: 0 AF3; MRR = (CROXD × F × N) / 1000 GON1; FLT: 1 13; ASA3;

Dimana:

  • 1f 1st; FLT: 0 = 0 = 33; D = 111; FLT: 1 123; = Diagorr of the workpiece (mm)
  • 1f 1f; 1f 1; FLT: 0 Aver3; f 1; FLT: 1 Aver3; = Feed rate (mm / revolution)
  • Spind3 (RPM)

Calculating Materiay Removul Rate kn Milling

For milling, the MRR formula is:

11; Syaria1; FLT: 0 AF3; MRR = (ap × ae fz × N) / 1000 1; FLT: 1 1f 3; 1f 3; 1f 3;;;

Dimana:

  • 1f 1f; 1f; FLT: 0 = 0 = 33. ap = aflo 1; FLT: 1 = Axial depth of cut (mm)
  • 1f 1f; 1f; FLT: 0 = 0 = 33. ae 1; 2.1; FLT: 1 123; = Radil depth of cut (mm)
  • 1f 1f; 1f; FLT: 0 1f 3. fz 1; 501; FLT: 1 123; = Feed per tooth (mm)
  • Spind3 (RPM)
