Maxsus kesish kuchi Kc nima?

Specific cutting force Kc (N/mm²) is the force per unit area of undeformed chip cross-section. It depends on material, chip thickness, and tool geometry. Typical Kc for steel is 1800–2500 N/mm².

Kesish quvvati qanday hisoblanadi?

Pc = Kc × ae × ap × vf / (60 × 10⁶) kW, where ae is width of cut, ap is depth of cut (both in mm), and vf is feed rate in mm/min.

Metall olib tashlash tezligi nima?

MRR = ae × ap × vf (mm³/min). It represents the volume of material removed per unit time and directly relates to cutting power.

Yetarli quvvatga ega mashinani qanday tanlash mumkin?

Mashinaning dastgoh quvvati Pc / η dan oshishi kerak, bunda η — dastgoh FIK (odatda 0.7–0.9). Xavfsizlik uchun 10–20% zaxira qo'shing.

Kc qirindi qalinligiga qarab o'zgaradimi?

Ha. O'lcham effekti tufayli ingichka qirindilarda Kc oshadi. Kc = Kc1 × h^(-mc), bunda Kc1 — 1 mm qirindi qalinligidagi Kc qiymati, mc esa material doimiysidir (0.2–0.4).

Metall olib tashlash tezligi

Misol — Po'latni yuzasini frezerlash

Given: Kc = 2000 N/mm², ae = 10 mm, ap = 3 mm, vf = 400 mm/min

Pc = 2000 × 10 × 3 × 400 / 60,000,000 = 0.40 kW

MRR = 10 × 3 × 400 = 12,000 mm³/min = 12 cm³/min
