How do you show hole size in Solidworks drawing?
To add a hole callout: Click Hole Callout (Annotation toolbar), or click Insert > Annotations > Hole Callout. Click the edge of a hole, then click in the graphics area to place the hole callout. Edit the callout in the Dimension PropertyManager. Repeat steps 2 through 4 to insert additional hole callouts, then click .
When creating hole features the depth specified in the drawing is defined as?
In hole wizard, the hole depth is defined as the distance from the surface to the cylindrical edge (5 mm in the example) below.
What is hole depth?
The hole depth is determined by the nozzle diameter and nozzle pressure drop irrespective of a casing or open hole well. The greater the nozzle diameter, the higher the nozzle pressure drop, and the stronger the breaking ability of the water jet, the greater the depth of perforation.
How do you specify hole tolerance?
Right-click on the pad or via and select Properties. In the Pad Properties dialog (Figure 1), hole tolerance can be edited under the Hole Information section. In the Via Properties dialog, hole tolerance can be edited using Tolerance, in the top left-hand corner of the dialog (Figure 2).
How are tolerances shown on an engineering drawing?
The sizes of parts and overall sizes of assemblies are conveyed by dimensions placed on the drawing. The difference between the acceptable maximum and minimum dimensions given for a hole, shaft, or other feature is known as the tolerance. In the example above the tolerance is 0.010 (that is, 2.005 − 1.995) inch.
How is a reference dimension shown on a drawing?
Reference dimensions are shown on a drawing as a value enclosed in parentheses. An alternate method is to follow the dimension with “Reference” or “Ref”. The use of “Ref” or enclosing the dimension inside parentheses are by far the most common notations used.
What is threaded hole?
Tapped holes are made in sheet metal parts by first starting with a laser cut hole. That hole is then treated with a treading bit to create threads in the hole for use with a screw or bolt with matching threads to hold a component or attaching the sheet metal part to another component.
What does thru mean engineering?
The problem with that is using it that way without an “official” definition. Taken literally (as most info on a dwg usually is) THRU means totally through the part, not just until you hit air. Thus THRU ONE WALL and other variations are often used. When in doubt, draw it out.
Do you dimension hidden lines?
Dimensioning to hidden lines should be avoided wherever possible. Longer dimensions should be placed outside all intermediate dimensions so that dimension lines will not cross extension lines.
What information is typically shown in a drilled hole note?
The depth of drilled holes, when stated in note form, refers to the depth of the cylindrical portion and not to the point left by the drill. If no other indication is given they are assumed to go through the material.
How do you measure a tapered hole?
The usual method of dimensioning a taper is to give the amount of taper in a note, such as TAPER 0.167 ON DIA. And then give the diameter at one end, plus the length, or give the diameter at both ends and omit the length.
Which of following is necessary for deep hole?
Which of following is necessary for deep hole? Explanation: L/d ratio should be very high for deep hole. If l/d ratio is high that means tool has large length compare to its diameter and then and then only it can make deep holes.
How is drill depth measured?
The length of the wellbore, as if determined by a measuring stick. Since the wellbore cannot be physically measured from end to end, the lengths of individual joints of drillpipe, drill collars and other drillstring elements are measured with a steel tape measure and added together.
What is hole tolerance?
For example, if a shaft with a nominal diameter of 10 mm is to have a sliding fit within a hole, the shaft might be specified with a tolerance range from 9.964 to 10 mm (i.e., a zero fundamental deviation, but a lower deviation of 0.036 mm) and the hole might be specified with a tolerance range from 10.04 mm to 10.076.
What is the difference between clearance and tolerance?
Stated simply, CLEARANCE is the distance between the adjacent surfaces of mating parts (how much the mating parts CLEAR each other), while TOLERANCE is the allowable variation of a dimension from its nominal (desired) value ( the amount of error one will TOLERATE ).
What is hole basis system and shaft basis system?
The two bases of a system of limits and fits are the hole basis and the shaft basis. In the hole basis system, the basic diameter of the hole is constant while the shaft size varies according to the type of fit.
What is thru hole in drawing?
A thru hole, also known as a through hole, is a feature on a blueprint or drawing that identifies a hole to be machined with two open ends. The hole goes all the way through the part. In other words, the hole breaks through at two locations on the part.
What is a hole in engineering?
A hole is an opening in or through a particular medium, usually a solid body. In engineering, a hole may be blind or through if it is partial or complete depth.
What does 4X mean on a drawing?
First, the fact that they are called out as “4X” means they are all in the same position relative to other features. Second, you never use construction lines or dimensions for things that are “obvious” from the drawing itself, like showing that the corners of the quadrilateral plate are all 90 degree angles!Aug 19, 2018.
