    SW2005 Insert Mate like Autodesk Inventor

    Hello All, I haven't used SW since version 99. I've been using an older version of Inventor. One handy inventor mate is the insert mate. Its basically a combined concentric and coincident. Very handy for mating two holes, a bolt or shaft to a hole. Is there a mate for this or do I have to do a...

    Need Torque Sensor

    My company builds a machine that takes a small door (1 ft x 1 ft X 1 in thk) off of a small container (1 ft cube). The door has two key holes that have to be turned 90 degrees to unlock the door for removal. The manufacturer of the container has asked us to add a torque sensor to measure the...

    Need source for black plastic pipe/tube

    Specifically I'm looking for a source for the black plastic pipe that are used to cover the lifting columns (gas cylinders) on adjustable height office chairs. That's right, you can probably take a quick peek between your legs and see an example right now!! They are usually two or three pieces...

    Looking for a miniature actuator

    Ampacity (of a wire) is the current carrying capacity. Basically its how much current a wire can handle before it fails. How small are the servos in remote controlled planes? I have found a Haydon linear actuator/stepper motor thats 15mm diameter...

    Looking for a miniature actuator

    Cycle life is a good question. I would like to have a cycle life in the millions, but I may be able to lower that, if I can make the mechanism cheap enough to sell it as a consumable/replaceble item. Ideally though we would have at least a 1 million cycle life. I do not have info yet on flow...

    Creating alternate position of parts in an assembly

    Well I'm stuck in Inventor 4, begging and pleading my bosses for an upgrade, but when I need to do this there are two options I've found: Option 1: Make a new presentation file. In the presentation file make two identical views of the assembly file. Leave the first view alone (call this the...

    Looking for a miniature actuator

    Thanks for all the help so far. I've checked out many of the suggestions. Festo has good air cylinders, but according to their tech, will not work with vacuum. I'm waiting for return calls from SMC and Clippard. I cannot find a solenoid that meets both the size and force requirements. The peizo...

    Looking for a miniature actuator

    Well it now seems I do not have a compressed air line, I only have a vacuum line (25 in-Hg). So, are there any vacuum operated cylinders? To answer the questions above: the cylinder would need to be spring return or single acting (spring on mechanism) and the mechanism will guide itself...

    Looking for a miniature actuator

    I'm looking for a miniature linear actuator that has a max cross-sectional size of .250" square and is no longer than about 3". I need it to exert between 1 to 2 pound-force and have a stroke of at least .188". Additionally it needs a fast response time (actuates and releases in less than 0.5...

    Need Aluminum Alloy to widthstand heat

    Thanks for the responses. Unfortunately we may not be able to get a real clear awnser form our customer on how these parts warped. I did find out however that the parts are placed in an over and slowed heated up to 250 C (482 F) and left for 72 hours. They are then left to cool to room temp...

    Need Aluminum Alloy to widthstand heat

    Is there and alloy with similar mechanical strength properties of 6061-T6 that can widthstand heat better than it. We use 6061-T6 to make a tool that holds devices in an oven. Typical thickness of the tool is about 1/2" and L X W is around 6" X 6". The 6061-T6 is warping. I'm...

    Greaseless TFE Leadscrews in cleanrooms

    I am looking for greaseless leadscrews for use in semiconductor cleanrooms. There telfon coated leadscrews (specifically I have used in the past leadscrews made from Kerk Motion Products). Greased leadscrews have been used at my current job in the past, but for ease of maintence, I want to...

    Bond/epoxy for cleanroom, stainless steel to ???

    I need to find a "cleanroom safe" epoxy or other adhesive to bond a cylindrical spacer (of a material that is yet to be determined)inside a stainless steel tube (.125" ID, .150" OD). I was planning on the undetermined material to be a plastic, such as PPS, Peek, acrylic, pvc...

    Getting my LED's to light up from stepper interface board!!!

    I did test the pin and I get 0V in fault and like 80-120 mV when fault is off. I wired the LED with the anode (+, long lead) to the resistor, and the cathode (-, short lead) to pin 12. I'll try doing it the other way, but intuitively that seems backwards. Thanks for the help guys!!!

    Getting my LED's to light up from stepper interface board!!!

    VDD (24V) | R = 2.2K (for 10mA current in the LED) | - V LED, be careful of the orientation | | pin 12 --- I tried this with no luck. LED was always off. I haven't tried the relay as of yet. Maybe time...

    Getting my LED's to light up from stepper interface board!!!

    Okay, that didn't work!!! The relay was always on. Why does the LED go On/Off, but the relay stays on. ... Just checked the voltage and its always at 24, in fault or not.

    Getting my LED's to light up from stepper interface board!!!

    I think I may be confusing you. The pin with +5V you mentioned above is on the IB-462H chip. I am interfacing to the INT-462 Interface Board shown on page 40 of the manual I linked to above. I found the five volts on the board and tried what was said above, but the LED never came on. Here's...

    Getting my LED's to light up from stepper interface board!!!

    Are you saying connect the LED anode to Vdd (plus series resistor) and cathode to pin 12, cause I tried this and the LED was always on? Was I using the wrong Resistor Value? Is below what you are saying I should do? I'll try it again, but I'm sure the LED was always on. 24V+...

    Getting my LED's to light up from stepper interface board!!!

    Okay, please help me, I am a confused Mechanical Engineer!!! I have a stepper driver board, which has built in fault protection. When the board goes into fault protection, I want to light up an LED. Here's what I have to work with: The fault protection pin pulls low when fault is on, and floats...
