The chart with log prices should be read as price per 1000 BF. In other words, if you add a decimal in front, that would be price per board foot. For example: Poplar: #1 250 would be read as $250/1000 BF or .25/BF. Poplar: #3 75 would be read as $75/1000 or .075/BF. Multiply the price per BF by the scale and that is the value of your log.

Example: A log with sap rot measures 12" in diameter. The rotten sapwood is 1" thick. The gross diameter of the log is decreased by 2", with ...

16.8 A peripheral milling operation is performed on the top surface of a rectangular workpart which is 400 mm long by 60 mm wide. The milling cutter, which is 80 mm in diameter and has five teeth, overhangs the width of the part on both sides. Cutting speed = 70 m/min, chip load = 0.25 mm/tooth, and

d = c / π. d=c/pi d = c/π. If written instead in terms of the radius, the diameter is very simple; it's just twice as long: d = 2 r. d = 2r d = 2r. Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) Area is the space contained within the circle's boundaries. It's also easy to find from any of the others.

D is the diameter of the tool . N. is the rotational velocity of the tool . Since the peripheral velocity is commonly expressed in units of f eet/minute and tool diameter is typically measured in units of inches, Equation 1 can be solved for the spindle or tool vel ocity, N in the following manner:

If the radial WOC equals the milling cutter diameter (D), the engagement angle has a maximum value of 180°, and the number of engaged teeth is half the number of teeth in the cutter: ...

Use your measurements with the attached table to determine the approximate number of board feet the log holds. The log in the above photos was 13 inches and 16′, so we estimate the log as having 115 board feet of lumber. Tim Knight. The board-foot contents of logs according to the International 1/4 Rule. Diameter of log small end, inside bark.

diameter 16-foot-long log is 0.240 inch for a mill cutting dimension lumber (fig. 4a). If the kerf on this log is reduced to 0.180 inch, the pattern shift results in a 2 by 6 rather than a 2 by 4, with an increase in lumber yield from 64 to 69-1/3 board feet–an 8.3 percent increase (fig. 4b).

Milling operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.

The largest vertical boring mill I've seen in the flesh was a Craven 42 ft diameter machine. This was impressively large, so I was amazed to learn that GE in the USA had a 60 ft VBM in about 1902. I recently came across some information about it. Turns out it wasn't as beefy as its capacity might imply, but the concept was very interesting.

5. It is recommended to use a TiCN coated cutter when milling with solid cemented carbide tools. The axial depth of cut should not exceed the cutter diameter when slot milling. 6. Climb milling is generally recommended. 7. When side milling with small radial depths of cut (a

The chip load, or feed rate in inch per tooth, can be approximated as a function of the actual diameter of the tool. For the starting point for a hard milling feed rate, use these ranges: Workpiece Hardness. IPT Feed Rate. Up to 45 HRC. 3 to 4 percent of tool diameter. 45-58 HRC. 2 to 3 percent of tool diameter. 60+ HRC.
