Obliczanie Feed rates and d cutting speeds is essential for efficient CNC machining. Proper calculations help optimize tool life, surface finish, and maching time. Thi article provides a clear, step-by- step approvach to perfom these calculations in CAM companare.

Understanding Cutting Speed

Cutting speed, meters in meters per minute (m / min), refers to thee speed at which the cutting tool moves relative te te workpiece. It depends on the material being machined and the tool used.

Tu calculate thee cutting speed, use the formula:

"R", jeżeli w polu występuje "R", "R", "R", "R", "R", "R", "R", "R", "R", "R", "R", "R", "R", "R", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "W", "," W "," W ",", "W", ","

Kalkulating Rate Feed

Feed rate determinates how fast the tool apvances the through gh the material. It is measured in militers per minute (mm / min). The feed rate depends one thee tool, material, and cutting conditions.

Thee formula for calculating feed rate is:

"FLT: 1; FLT: 0; FET: 0; FET: 3; FET: 3; FET: 3; FLT: 2; FLAE: 3; FLAE; FLAE: 3; FLAE: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAS: 3; FLAN: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: 3; FLAT: FLAT: 3; FLAT: 0; FLAT: 0; FLAT: 0; FLA@@

Praktyka Badanie

Suppose a tool has a diameter of 10 mm, with 2 teeth, and the spindle speed is set to 1500 RPM. The recommended feed per tooth is 0.02 mm.

First, calculate the cutting speed:

V = ∞ × 10 × 1500 / 1000 -------------------------------------------------- 47,12 m / min

Next, calculate thee feed rate:

F = 0,02 × 2 × 1500 = 60 mm / min
