Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. For example; when drilling, run-out will result in a larger hole than the drill's nominal diameter due to the drill being rotated eccentrically (off axis instead of in line).

2020年9月9日 · Runout is how much one given reference feature or features vary with respect to another datum when the part is rotated 360° around the datum axis.

Runout is the total variation that the reference surface can have when the part is rotated around the datum’s true axis. Gaging / Measurement: Runout is measured using a simple height gage on the reference surface. The datum axis is controlled by fixing all datum points and rotating the central datum axis.

2023年2月24日 · Runout is a specific type of manufacturing error that applies to rotating parts like motor shafts. It measures the deviation of these parts as they rotate about a fixed reference axis. Ideally, the part’s axis and the reference axis should be …

2014年12月13日 · Total Runout is how much one entire feature or surface varies with respect to a datum when the part is rotated 360° around the datum axis. Total runout controls both the amount of variation in the surface as the part is rotated, but the amount of variation in the axial dimension.

2020年4月3日 · Runout (Run-out) is the error of rotating mechanical system, especially the rotation direction of tool or shaft is not completely consistent with the main axis, its often applied to assembled parts with circular cross-sections, such as drill bit and segmented shafts.

2023年9月6日 · Runout is a critical concept in precision machining and plays a significant role in ensuring the quality of machined parts. It refers to the variation in motion or position of a surface as a rotating part turns about an axis.

Runout is a critical concept in engineering and manufacturing that affects the precision and performance of mechanical components. Whether you’re working with shafts, gears, or other rotating parts, understanding runout and how to measure it …

In machining, runout refers to inaccuracies in a tool or piece of equipment that cause it to spin off its ideal axis. Spindle runout occurs when a spindle no longer rotates on its intended axis, which can result in: Inaccurate machine registration; Issues with tolerance control; Excessive chip load; Poor part finishes; Insufficient tool life

2024年12月17日 · Shaft runout occurs when the rotating shaft strays from the centerline and moves with eccentricity. Typically, shaft runout is caused by coupling defects or by bent shafts. In extreme cases, shaft runout gives the shaft a clear wobble. But shaft runout isn’t always visible to …
