This makes the weldment drawing easier to read and understand.

How to read machining drawing. The holes and other machining can now be dimensioned. The title block contains information such as. Located in the lower right of the drawing the Title Block contains the architect or designers name the drawing number project name part number or building address and the scale of the drawing.

Look over the lines. It is also important to have an understanding of how to read them. Christian Mullen is a.

Identify the hidden lines. Start by looking at the Title Block on each drawing. The Purpose of Engineering Drawings.

Start off by reading the title block found at the bottom right-hand corner of the drawing. Reading Lines 1. An engineering drawing such as those for your cast part and machined part is a set of requirements for a finished part condition.

The term technical drawing has a very broad meaning referring to any. 38 1 Read as 38 inch on the drawing equals 1 foot on the actual component or system. See this and over 140 engineering technology simulation videos at httpwwwengin.

1 1 Read as 1 inch on the drawing equals 1 inch on the actual component or system. The drawing should define those requirements as completely and specifically as possible since anything not defined on the drawing. It covers several fundamental topics1 The layout of the drawing2 Title block3 First VS.

These views will have just the dimensions for the machining done after the parts are welded together. Measuring tools must be kept calibrated to make sure that all dimensions are measured properly and that the tolerances are followed with absolute accuracy. It is presented through a number of orthographic views so that the size and shape of the component is fully understood.

This video discusses the basics of reading engineering drawings. Object lines - or visible lines - are drawn the thickest of all on a blueprint. Sheet number and number of sheets.

If the weldment is large and complex it is a good idea to start with new views of the weldment possibly on a new sheet. 5e presents an example of general information about the surface roughness of an object within a construction drawing as well as an executive drawing. This can also be stated as FULL SIZE in the scale block of the drawing.

D the surface should be processed grinded and the roughness after machining should be Ra 5 a strictly defined machining method is indicated. The machinist must know how to read them properly and must also know which tools to use to take the raw material to a completed part. Name and address of the company or agency who prepared or owns the drawing.

HOW TO READ EN. Identify all the object lines. Part drawings and assembly drawings belong to this classification.

In todays modern age of CAD models and CAM programming one could assume that weve moved beyond the times when part prints and CNC drawings were commonplace in manufacturing. The Basics Of CNC Machining Drawings The Basics Of CNC Machining Drawings. About a year ago I met an older automobile machinist at a gathering with friends and he said that lately newer engineers have been sending drawings that are impossible to manufacture.

Any information in the notes that conflict with. There are other information blocks like it but the title block serves as the context in which the drawing should be perceived. Watch this video to learn more about reading and drawing blueprint lines.

So once a manufacturing engineer gets the drawing he can start the production process without a second thought. The measured distance on the drawing is the actual distance or size of the component. As already said such a technical drawing has all the information for manufacturing a part or welding and building an assemblyThe info includes dimensions part names and numbers etc.

Drawing but also to read the drawing correctly. I think its a combination of the impact of 3D printing 3D CAD and a lack of education about machining. After all there is a great deal of information that can be pulled from a 3D model so.

Classifications of Drawings 41 Machine Drawing It is pertaining to machine parts or components.
