Part/Feature Layout

Layout is an essential process in machining that involves marking out the locations of features to be machined on a workpiece.

• However, it is crucial to note that layout should not be used as the primary method of locating features to be machined.

• Instead, it should only serve as a double-checking mechanism to ensure that the machining process is done correctly.

  • For instance, after precisely locating the edge of a part using an edge finder or another probing tool, the mill is moved a measurable amount using either the scales on the axes dials or the DRO. If the tool does not align with the layout marks, something went wrong in the process, such as an error in layout, edge finding, math, movement, or other factors.

• When performing layout, the standard layout fluid used is Blue Dykem. However, other brands and colors can also be used depending on the specific requirements of the task at hand.

  • While Dykem is a good quality layout fluid, it also stains everything it touches (fingers, clothing, tools, etc. and is near-impossible to remove without using Dykem Removal Fluid

  • An acceptable alternative to Dykem for light-duty layout is to use a blue or black permanent marker (Sharpie), which stains less and is easier to remove
