What is Trim in Aerospace Engineering?

Trim is the precision machining process of removing a small amount of material from a part to achieve the desired dimensions. Trimming can be done with precision milling machines, lathes, and grinders. The aerospace industry uses trimming to ensure that all parts are uniform and precise for assembly purposes.


What is Trimming?

Precision machining is an integral part of the design process in aerospace engineering. All parts have tolerances that must be met for proper installation and function. A small error on a large piece can lead to major consequences during aircraft assembly or rocket launch.


Trimming is a precision machining process that removes excess material from a piece manufactured by another process or generated by another machine. The process involves removing excess material to achieve desired measurements within planned dimensions that will not alter the object’s shape.


Trimming is often done with CNC Plasma cutting, laser trimming, or gas discharge machining.


Precision Tooling Used in Precision Machining Aerospace Components

Precision machine tools help aerospace engineers meet quality control standards. They also allow manufacturers to reduce the amount of excess material used in manufacturing parts for aircraft assembly lines.

Precision milling machines:  They are used to create internal and external surfaces of parts. The machine can make fine details, which allows for intricate designs that may not be possible with other processes like laser cutting or plasma cutting.

CNC Trimming: This aerospace machining technique uses computer numerical control tools to produce trim parts. It does this by applying a milling cutter with the CNC machine, and it trims material from surfaces while maintaining tolerances within .0002″ of its designed dimension.

CNC lasers can cut metal up to three times faster than traditional CNC machining methods due to their extremely high power density. The laser is used to create internal and external surfaces of parts and can also be used for removing material from a part in the trimming process like CNC plasma cutting.


Why is Trimming Used in Aerospace Engineering?

Trimming has many benefits for aerospace engineering because it allows engineers to make precise measurements during every stage of the design process.


Trimming in aerospace engineering allows precise measurements of parts so that products can be made with minimum deviations from planned dimensions allowing for more efficient assembly during production with the highest performance possible.
