Kalkulating feeg rate and cutting speeds is essential for esent CNC maching. Proper kalkulations help optimize tool lifa, surface finish, and maching time. Ini article provides a grip, stephance -step ach perfores tme reversartionie.

Understanding Cutting Speed

Cutting speed, metered yone meters per minute (m / myn), referens to the speud att whit cutting tool moves relative te worpiepe.

To kalkulate the cutting speed, use the formula:

S01; S01; FLT: 0 AF3; Cutterig Speed (V) = Ax× D × N / 1000 IS1; FLT: 1 = 1 123; CONT3;

Dimana:

  • 1f 1f; FLT: 0 133; D 1f; FLT: 1 123; = Diagorr of the tool in milimeters
  • 1f 1f; 1f; FLT: 0 = 33; N = 1f 1; FLT: 1 1f 3; = Spindle speeded ion RPM

Calculating Feed Rate

Feed rate deterset how fast tome toool procecesss threogh material. Ini is etid in millimeters per minute (mm / min).

Ini untuk kalkulating for feed rate is:

FLT: 0 = Feed Rate (F) = Feed per Tooth (f Number Tee1; FLT: 1: 1 AF3; z Syon1; FLT: 2: 3333T; xo Number Teeth (z) & gt; & lt; 333222E;

Dimana:

  • Pertama; FLT: 0; 3; f 1; FLT: 1: 1 13.1; z 1f 1; FLT: 2; S3; FLT; FLT: 3: 3: 3 MIL; 3 MISKIN; = Feed per tooth in mm
  • 1f 1st; FLT: 0 = 0 = 33; z = 1f; FLT: 1 123; = Number of teeth on tool
  • 1f 1f; 1f; FLT: 0 = 33; N = 1f 1; FLT: 1 1f 3; = Spindle speeded ion RPM

Pemeriksa Praktek

Supposea tool has a diametorof 10mm, with 2 teetch, and the spindle is set to 1500 RPM.

First, kalkulate untuk cutting speed:

V = × 10 × 1500 / 1000 47.12 m / min

Next, kalkulate the feed rate:

F = 0.02 × 2 × 1500 = 60 mm / min
