This formula is used to calculate the cutting speed from the spindle speed and the outer diameter of the cutter. Example: Cutter diameter (DC) = 100 mmSpindle speed (n) = 400 min-1In this case, the cutting speed (vc) is approximately 125.6 m/min.

This page introduces formulas for calculating basic parameters necessary for face milling. The figures obtained from the calculation are for reference only. The conditions for machining depend on the machine tool you are using. Use the optimal conditions according to your actual machining circumstances.

I’ve been fascinated by machinist’s chests since the first time I saw one. Wonderful, warm, wooden chests of drawers filled with strange, precise, and unusually-shaped, finely-made tools. I chose a larger scale, that of 1/8th opposed to the more common scale of 1/12th, for the size of this miniature.  That way I could capture the fine details such as the engraved lines on the rules.

Dec 29, 2018 — There's a whole lot of math that goes into finding the perfect feed and speeds. I'm not a mathmatician, but there are plenty of websites that ...

This formula is used to calculate the table feed per minute (feed rate) from the feed per tooth, the number of teeth, and the spindle speed. Example: Feed per tooth (fz) = 0.2 mm/toothNumber of teeth (z) = 8Spindle speed (n) = 600 min-1In this case, the table feed rate is 960 mm/min.

This formula is used to calculate the net power required for face milling based on the depth and width of cut, the table feed per minute, the specific cutting force, and the machine efficiency. Example of calculating the net power required to cut tool steel with: Depth of cut (ap) = 5 mmWidth of cut (ae) = 70 mmTable feed per minute (vf) = 300 mm/min Other conditions: Specific cutting force (Kc) = 1800 MPaMachine efficiency (η) = 80% (0.8)Cutting speed (vc) = 80 m/minCutter diameter (DC) = 250 mmNumber of teeth (z) = 16 In this case, first you calculate the spindle speed (n) and then the feed per tooth of the cutter (fz). Spindle speed (n) = 1000・vc ÷ π・D = (1000 × 80) ÷ (3.14 × 250) = 101.91 min-1Feed per tooth (fz) = vf ÷ (Z × n) = 300 ÷ (16 × 101.91) = 0.184 mm/toothSubstitute the above into the formula: Pc = (5 × 70 × 300 × 1800) ÷ (60 × 106× 0.8) = 3.937 kwThe net power required for face milling (Pc) is approximately 3.94 kW.

This formula is used to calculate the feed per tooth from the table feed per minute (feed rate), the number of teeth, and the spindle speed. Example: Table feed per minute (vf) = 450 mm/minNumber of teeth (z) = 10Spindle speed (n) = 600 min-1In this case, the feed per tooth (f) is 0.075 mm/t.

The RIDGID 1-3/8 in. Wet Diamond Hold Saw Kit. This kit is perfect for cutting holes for faucet installation, pipes, and shower heads.

The six chests were made of mopane, an African wood that looks like a miniature version of mahogany, or cherry. Pear wood was used as the secondary wood on the interior and ebony for the moldings. Hinges, handles and knobs are made in a shield shaped pattern. The lock works and is made from brass and steel. Inside the lid I pasted a scaled down version of a trade card from the Centennial Exhibition in Philadelphia, a decimal equivalents chart and photos of loved ones. That is a photo of my teenaged grandmother and aunt—two girls who would never expect to have their image on the inside of a tool chest.

This formula is used to calculate the machining time from the total table feed length and the table feed per minute (feed rate). Example of finishing a block of FC200 cast iron to have a flat surface of: Width = 150 mLength = 250 mmFace milling conditions used: Feed per tooth (fz) = 0.35 mmNumber of teeth (z) = 12Spindle speed (n) = 200 min-1Cutting speed (vc) = 120 m/minFace mill diameter (D1) = 220 mmIn this case, the table feed per minute (vf) and the total table feed length (L) are:vf = 0.35 × 12 × 200 = 840 mm/minL = 350 + 220 = 570 mmSubstitute these values into the formula: Tc = L ÷ vf = 570 ÷ 1120 = 0.679 (min) × 60 = 40.74 (sec)The machining time (Tc) is approximately 40.74 seconds.
