Hi All,
I am using a low power geared (hobby) motor that has a time constant of about 0.002 sec. I would like to slow this down closer to 0.2 seconds. My first thought was to add a LP filter and a buffer (see attached) before the motor. The buffer has ±18V (2 9V batteries) at the rails. The...
In my experience all employers have employed the "every change gets a revision." Meaning if I have Part1 at Rev A, get it manufactured and sent back to me, then find out it doesn't fit, I then revise Part1 to Rev B (no new part number).
I am aware of the "parts get no revisions" rule and it...
I'm trying to find a legitimate way for calling out a bend on a part that has a flat on the end. Essentially, I want to say "the flat must remain perpendicular to the plane of the bend (which is my "A") by this much." Since the part is cylindrical I don't really have a good reference to relate...
Can someone please explain the following. I am looking at what exactly drawing numbers are and why they differ from part numbers. Most things that I have seen say something along the lines of "part number is 12345-01 and drawing number is 12345." I understand the dash number in the part number...
One example uses parallelism and perpendicularity while the other uses profile. I'm sure they are inspected differently but are they geometrically the same thing?
Thanks in advance,

The standard states in paragraph 3.1 "The [clearance] drill sizes were selected to provide as practical a step-patterned clearance for the minimum recommended hole." Can someone explain what this means. I am just curious how they determined the clearance hole sizes and it seems to be embedded in...
I have noticed in the engineers handbook (30th ed) there are a few instances where clearance hole sizes are tabulated for inch fasteners. For instance, in the section Fasteners -> Metric Threaded Fasteners -> Clearance Holes for Bolts, Screws, and Nuts (p. 1659) there is a table that uses ASME...
Attached is a sketch for trying to locate a hole relative to another hole that is in a different plane with a looser +/- tolerance. Essentially what I am trying to say in the FCF is "this hole is to be parallel to A and located vertically from it's respective basic dimension, it's center is to...
Attached is how my company is calling out a coplanar profile of three surfaces that are not in-line with one another. I am still learning ASME Y14.5 and wanted to ask if this is an acceptable way of doing this or if better methods exist. I have seen profile used to callout coplanar surfaces when...
This is just an example I made up to see if my understanding of datums with position tolerances is correct. Let's say I have a pin hole that is located relative to datums A, B, C with a tolerance of .002" - no problems there. Now let's say I want to locate two threaded holes relative to the...
I purchased a Pittman brushed DC motor with a 500 count/rev encoder. I noticed quite a bit of oscillation in the encoder signal when the shaft is rotating at a constant rate. After running some tests I started to notice a trend. For instance, when I ran the motor at an average 600 RPM (averaged...
