Common calculation formulas for CNC programming and  Vertical machining center  machining

Trigonometric calculation

1.tanθ=b/aθ=tan-1b/a

2. Sinθ=b/c Cos=a/c

2. Calculation of cutting speed

Vc=(π*D*S)/1000

Vc: Linear speed (m/min) π: PI (3.14159) D: Tool diameter (mm)

S: speed (rpm)

Example. Using Φ25 milling cutter Vc is (m/min)25 to find S=?rpm

Vc=πds/1000

25=π*25*S/1000

S=1000*25/ π*25

S=320rpm

3. Calculation of feed amount (F value)

F=S*Z*Fz

F: Feed rate (mm/min) S: Speed (rpm) Z: Number of blades

Fz: (actual feed per edge)

Example. A standard 2-flute end mill cuts a workpiece at a speed of 2000rpm, find the feed (F

value) is how much? (Fz=0.25mm)

F=S*Z*Fz

F＝2000*2*0.25

F＝1000(mm/min)

4. Calculation of residual material height

Scallop=(ae*ae)/8R

Scallop: residual material height (mm) ae: XYpitch (mm) R tool radius (mm)

Example. Φ20R10 refines 2 blades, the height of the pre-residual material is 0.002mm, how much is the Pitch

few? mm

Scallop=ae2/8R

0.002=ae2/8*10

ae=0.4mm

5. Calculation of material escape hole

Φ=√2R2 X, Y=D/4

Φ: escape hole diameter (mm) R tool radius (mm) D: tool diameter (mm)

Example. It is known that a mold cavity must be processed with escape corners (as shown in the figure),

The milling cutter used is ψ10; what is the minimum escape angle hole

for how much? What are the coordinates of the center of the circle?

Φ=√2R2

Φ=√2*52

Φ=7.1(mm)

X, Y=D/4

X, Y=10/4

X, Y = 2.5mm

The coordinates of the center of the circle are (2.5,-2.5)

Six, the calculation of the amount of material

Q=(ae*ap*F)/1000

Ｑ: Feed amount (cm3/min) ae: XYpitch (mm) ap: Zpitch (mm)

Example. It is known that a mold is processed with the same height as the cavity, and the XYpitch of the Φ35R5 knife is 60% of the tool. Each layer cuts 1.5mm, and the feed rate is 2000mm/min. What is the reclaiming volume of this tool?

Q=(ae*ap*F)/1000

Q＝35*0.6*1.5*2000/1000

Q＝63 cm3/min

High-speed and high-rigidity spindle can demonstrate powerful power

Stable operation, full of power and stronger

Vertical machining center  features

Mainly used in the processing of small and medium-sized parts and molds. After the workpiece is clamped once, milling, drilling, boring, and comparison can be completed continuously.

It can be used in a single machine for processing in various processes,

Vertical machining center  testing

The company has mature finishing equipment and testing equipment to provide a strong guarantee.

Perfect quality management system.

1/Spindle vibration detection

2/Spindle tension test detects the broaching force of each spindle

3/Spindle temperature test, whether the spindle temperature is abnormal after the spindle runs for 24h

4/Spindle deflection test

5/Spindle coupling detection

6/ Tool magazine load test detects tool magazine load and tool change 24h without exception
