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)
