learn moreFactsheet The relation between speed and crashes
The relation between speed and crashes . Summary The exact relation between speed and crashes depends on many factors. However, in a general sense the relation is very clear: if on a road the driven speeds become higher, the crash rate will also increase. The crash rate is also higher for an individual vehicle that drives at higher speed than the other traffic on that road. As speeds get ...

Determining Safe Wood Lathe Speeds. By Craft Supplies USA August 9, 2012. 1. Using the correct lathe speed should allow the blanks to be turned with little or no vibration, allowing the tools to produce a clean surface. This allows for a safer woodturning experience. Vibration is usually caused by speeds high enough to cause the unbalanced blank to vibrate the lathe, as the piece is trying ...
learn moreMilling Process, Defects, Equipment
In milling, the speed and motion of the cutting tool is specified through several parameters. These parameters are selected for each operation based upon the workpiece material, tool material, tool size, and more. Cutting feed The distance that the cutting tool or workpiece advances during one revolution of the spindle and tool, measured in inches per revolution (IPR). In some operations the ...
learn moreDriveshaft Critical Speed Pontiac
Critical Speed: This is the probably the most influential factor in driving the purchase of an aftermarket driveshaft. The critical speed of a spinning shaft is described as the lowest speed which excites the shaft at it''s natural frequency of vibration. This will cause the shaft to bend under the stress of vibration coupled with the centrifugal forces due to the rotation. In english, this ...

The rules and principles of cutting speeds and RPM calculations apply to all of the operations being performed on drilling machines. An example of this would be reaming. Reaming is done at half the speed and twice the feed as drilling. This rule still applies on the drill press as it does on the milling machine or the lathe. Pay very close attention to the information introduced in this unit ...

Cutter speed (rim speed) is a lot more critical in metal working that wood, but this is why it is difficult to use router bits in a shaper. The shaper has a slower shaft speed, mainly due to its being generally designed for larger diameter cutters. Likewise, the same reasoning applies to why you slow down a router as the bit diameter increases. It all relates to the force being applied to the ...

Cutting speed is the speed at the outside edge of the part as it is rotating. This is also known as surface speed. Surface speed, surface footage, and surface area are all directly related. Two wheels can illustrate this. Take two wheels, one wheel which is three feet in diameter and the other wheel which is one foot in diameter, roll each wheel one complete turn (Figure 1).

Speed vs Velocity . Speed is a scalar quantity, it does not account for direction, while velocity is a vector quantity which is aware of direction. If ran across the room and then returned to your original position, you would have a speed — the distance divided by the time. But your velocity would be zero since your position didn''t change between the beginning and the end of the interval ...
