Pierce Aluminum, in tum, sells material of different sizes and

shapes to distributors and other manufacturers. Material is sold in

sheets or cut to size in rolls. U.S. Sheet metal manufacturers work

with standard 8ft - 12ft stock sheets. For larger quantities, the

material is usually supplied in rolls. For a few cents more per

pound, sheet metal manufacturers request the supplier to shear the

material to a custom size.

Check Dual Dimensioning from Tools, Options Document

Properties to display both Metric and English units. Do not waste

raw material. Optimize flat pattern layout by knowing your sheet

metal manufacturer's equipment.

Discuss options for large cabinets that require multiple panels and

welds. In Project 1, you were required to be cognizant of the

manufacturing process for machined parts.

In Project 4 and 5 you created and purchased parts and recognized

the Draft feature required to manufacture plastic parts.

Whether a sheet metal part is produced in or out of house,

knowledge of the materials, forms and layout provides the best cost

effective design to the customer.

-;Q~ Save manufacturing cost and time. Obtain a list of standard

dies and forms from your sheet metal manufacturer. Utilize their

standard dies and forms at the start of your design. Prepare for

lead-time if custom dies and forms are required.

You require both a protective and cosmetic finish for the

Aluminum BOX. Review options with the sheet metal vendor.

Parts are anodized. Black and clear anodized finishes are the most

common. In harsh environments, parts are covered with a

protective coating such as Teflon® or Halon®.

The finish adds thickness to the material. A few thousandths could

cause problems in the assembly. Think about the finish before the

design begins.

Your sheet metal manufacturer suggests a pattern of square cuts

replace the Louvers for substantial cost savings. Suppress the

Louver. The Linear Pattern is a child of the Louver. The Linear

Pattern is suppressed. Utilize the Sketch Linear Step and Repeat

option.
