Still intimidated? Well, new users can opt to have the software automatically set default setting values based off of what press is connected, even if the user doesn’t know himself (the software can read the ID chip built into the FEC press unit). This way the press can be running, right out of the box, in just a few minutes.

So, now that you’ve gotten over your initial programming fears, let’s go and set up a part; in your case, pressing a rubber bushing into a shock absorber.

Because you are bottoming out the tooling to set the correct bushing position, we will initially press to a Target Load value. Now, we need to set the Target Load to a value high enough to make sure we fully press the bushing (known high limit or maximum press rated load, etc.).

After we’ve finished pressing the bushing, let’s look at the generated force curve. The FEC software’s CURVE screen shows us a scalable graph along with the final force and distance values. Also, when we move our cursor around in the graph area, we can see what the load and distance is at the cursor position. If we move our cursor to where the curve just begins to rise, we can determine that the bushing first entered the shock bore at 34.151mm. And, according to the screen, the final distance was at 58.47mm.

Now let’s go back and tweak our program based off of this information.

When you are assembling parts with a very tight press-fit (IE: the part that you are pressing is considerably larger than the bore it is being pressed into), the press needs to be slowed down to its slower “Press Speed” before it contacts the bore. This is to limit shock forces generated as the parts come together, which could eventually damage the press and/or tooling. Since we know that, according to our graph, the bushing contacts the shock at 34.151mm., we should set our PRESS SPEED 1 DISTANCE (the distance where we change to Press Speed) to at least 1mm before that (33mm). Since we know that our tooling contacts the shock at 58.47mm (Final Distance), we can set our PRESS SPEED 2 DISTANCE to 1.5 ~ 2.0mm before that (57mm).

We will initially set our Approach Distance at 10mm before part contact and set our speeds as recommended for the size of the press were using.

Later, we can add some in-process quality “checks”; Interference Check, Part Check, Band Check, etc.. All with the same simple, picture-based ease of the initial part setup.
