AutoForm-Trim is an add-on module for the tryout of trimming dies which is used to determine the optimum trim line and blank outline. In order to find the optimal trim line or blank outline, AutoForm-Trim iteratively runs multiple AutoForm-Incremental tryout simulations. Unlike an inverse one-step simulation, an advantage of AutoForm-Trim is that it considers several forming steps (instead of only one), and the resulting accuracy is much higher.

The AutoForm-Trim software module provides the following benefits:

	Rapidly determines the optimum trim line – typically with less than five AutoForm-Incremental iterations
	Saves time and costs by allowing the trim die to be developed simultaneously with the draw die, thus enabling concurrent engineering
	Shortens the design cycle for the complete tool set
	Reduces laser-trim tryout time for complex parts – typically saving several days

AutoForm-Trim is typically used for two applications: It determines the optimum trim line of a sheet metal part before restrike or flanging operations, with the trim line determined so that the sheet boundary takes the desired geometry at the end of the forming steps following the trimming operation.

When applied to the blanking operation, AutoForm-Trim helps to establish the blank outline necessary for near-net-shape manufacturing (crashforming) so as to produce the part without trimming.

AutoForm-Trim’s main features include:

	Automatically determines the blank outline for near-net-shape manufacturing (crashforming)
	Automatically calculates multiple blank outlines (e.g. when there are several target boundaries in the form of hole contours or inner cut contours in the blank)
	Calculates customer-specified (local) segments of the blank or cut outline
	Simultaneously determines all cut-out lines for several cutting operations, during one trim tryout
