In turning, the rate and motion of the cutting device is defined with numerous specifications. These criteria are picked for each and every procedure based upon the work surface material, device material, device dimension, as well as more.
Cutting feed – The range that the cutting tool or workpiece developments during one revolution of the spindle, measured in inches per transformation (IPR). In some procedures the device feeds into the work surface and in others the workpiece feeds into the device. For a multi-point tool, the cutting feed is additionally equal to the feed per tooth, measured in inches per tooth (IPT), multiplied by the number of teeth on the reducing tool.
Cutting speed – The speed of the workpiece surface relative to the side of the cutting tool throughout a cut, gauged in surface area feet per min (SFM).
Pin rate – The rotational rate of the spindle and also the work surface in revolutions per minute (RPM). The spindle speed amounts to the cutting rate split by the area of the workpiece where the cut is being made. In order to keep a continuous cutting speed, the spindle speed have to differ based upon the size of the cut. If the spindle rate is held constant, after that the cutting speed will differ.
Feed price – The speed of the reducing tool’s activity relative to the work surface as the tool makes a cut. The feed price is measured in inches per minute (IPM) as well as is the item of the reducing feed (IPR) and the spindle speed (RPM).
Axial depth of cut – The deepness of the tool along the axis of the workpiece as it goes through the turned parts manufacturer, as in a facing operation. A big axial depth of cut will need a low feed rate, otherwise it will lead to a high load on the device and decrease the device life. For that reason, a feature is usually machined in numerous passes as the tool relocates to the specified axial depth of cut for each pass.
