TABLE OF CONTENTS Study of any die set catalog will reveal that a number of dimensions are not given. There are three ways of establishing dimensions that are not listed in a catalog:
Dimensions may be estimated. Those dimensions that are not listed are not critical and may be approximated to proportions printed in the catalog.
Dimensions may be established with proportional dividers. The point relationship of the divider arms may be set to one of the given dimensions. Points are transferred from the catalog views to the views of the drawing.
When a component must be drawn at frequent intervals, missing dimensions may be measured and recorded in a standards book for future use.
Figure 17.16 gives all dimensions that are not ordinarily listed in die set catalogs. These dimensions may be used directly when applying the views of the die set to your drawings.
A proper working procedure reduces loss of time in laying out die sets. Seven steps are required (Figure 17.17):
Represent the left and right sides of the die set by vertical lines, as shown in the illustration.
In addition, the vertical center of the die set has been established. Preferably the die is centered between the posts and the front of the die set. Look up this dimension in the catalog, then draw horizontal lines to represent the front of the die set. Dimension A between posts and die block should be...
