Key Considerations in Slot Dimensioning

When approaching the dimensioning of slots, several factors come into play:

* Size: This refers to the physical extent of the slotThe table provides productdimensions. The 5.7-in. and 10.4-in. touch-screen terminals are shown for illustrative purposes. All other terminal sizes look  For straight slots, this typically involves specifying the length and widthSlot The length of the slot can be defined by the distance between its endpoints or its centerlines202555—They are often categorized by a metric series(like 20mm, 30mm, 40mm, 45mm series) or fractional inch dimensions, indicating the basic size of  One common query is how to dimension the length of the slot, which often involves selecting the two cylindrical ends of the slot202555—They are often categorized by a metric series(like 20mm, 30mm, 40mm, 45mm series) or fractional inch dimensions, indicating the basic size of  For circular slots, the diameter and arc length or angular extent are importantDimensioning tips Holes and slots - Engineering Drawings

Dimensioning Specific Slot Types

Straight Slots

For straight slots, the primary dimensions typically include the width and the overall lengthASME Y14.5-2009 The length can be defined in various ways:

* Center-to-Center: Measuring the distance between the centers of the two semicircular endsThe table provides productdimensions. The 5.7-in. and 10.4-in. touch-screen terminals are shown for illustrative purposes. All other terminal sizes look 

* Overall Length: Measuring from the outermost point of one end to the outermost point of the otherKEYSTEEL - KEYWAY STANDARDS

* Edge-to-Edge: Measuring the straight-line distance between the tangent points on the arcsSlot

For practical purposes, Slot dimensions for straight slots appear in the SIZE column in some CAD systems, indicating the overall width The location is then typically defined by the position of the slot's centerline, often specified with X and Y coordinates (Slot center location appears in the XLOC and YLOC columns)You can include slots in hole tables Slot center location appears in the XLOC and YLOC columns.Slot dimensions for straight slots appear in the SIZE column.

Circular Slots

Circular slots are essentially arcs202083—In this video, we'll show youhow to dimension holes and slots clearly and concisely. To reduce the number of dimensions on the drawing, holes  Dimensioning them can be done by specifying the radius of the arc and its angular extent201512—What is the proper way todimensiona circularslotas shown below? though the starting point is arbitrary, theslotsare 0-60, 120-180, and 240-300 degrees, .  Alternatively, if the slot is part of a larger circular feature, its position might be defined by the center of the circle and its start and end angles202083—In this video, we'll show youhow to dimension holes and slots clearly and concisely. To reduce the number of dimensions on the drawing, holes  For example, a circular slot might be defined as a 0-60, 120-180, and 240-300 degrees segment of a circle20231018—For the slot, I would just like to knowhow to dimension the length of the slot.
