Materialet Removal Rat (MRR) er en key metric in product processes such his turning and d milling. Det måler denne volume af materia l remove from a workpiece ovein a specic period. Understanding ing calculating MRR helps optimize machininining effektivitet og tool life.

Understanding Materal Removal Rate

MRR 's ekspressive virkning på den kemiske industri er ikke begrænset til en enkelt produktion af en maskine.

Calculating Material Removal Rate in n Turning

I turning, MRR can be calculatedusing the formula:

1; 1; FLT: 0; 3; MRR = (π × D × f × N) / 1000; 1; FLT: 1; 3; 3;

Whele:

  • = Diameteret for denne arbejdsenhed (m)
  • = Feed rate (m / revolution)
  • = Spindle speed (RPM)

Calculating Material Removal Rat in n Milling

Fr milling, the MRR formula is:

1; FLT: 0; MRR = (ap × ae × fz × N) / 1000

Whele:

  • = Axial depth ofcut (m)
  • = Radial depth ofcut (m)
  • = Feed por tooth (mmm)
  • = Spindle speed (RPM)

Optimizing Material Removal Rate

Det er vigtigt at finde en balance, der er så effektiv, at den bevarer sin kvalitet.
