    A CNC machine moves a rotating spindle with a cutting blade in three dimensions, X, Y and Z. So that it can do this well, the spindle has to be precisely aligned to the machine bed in two axes. The machine I have has these adjustments (called "Tramming") but they are poorly designed. The Spindle bolts onto a vertical plate. I need a design to add an intermediate plate that can be easily adjusted at four points and once set into position locks there. In the first picture you see the current spindle assembly from the side. On the far right is the spindle. It is attached to a 6mm aluminium plate (blue) and that plate is moved up and down by the mechanism you see to the left of it. In the second and third pictures, you can see how the spindle is attached to the plate by those fo...

    The attached picture shows the custom designed wine cellar the client wants. They would like the top half to be able to move down for them to select a bottle of wine. The top half would be a single bottle wine system and the bottom half would be a double bottle wine system. The wine cellar is a standup wine cellar that consists of two panels. The bottom panel (half) will have a 2 bottle deep wine panel- this panel will remain in place for the entire time and does not need to move. The top panel (half) the client wants on a motorized mechanical system that allows them to bring it down to the ground in order to select a bottle of wine and then put it back up. The system that brings the wall down to the ground is the system I need help with determining what system I need

    I am doing a project. I conventional engine we use cam to open the valve and to close the valve we are dependent on the spring. I my project i have made a prototype that opens and closes the valve solely using cam. ie. springs are eliminated. The objective of my project are---- 1). I want to show that in the conventional system there is a valve float scenario which is eliminated in the proposed model. 2). Vibrations are eliminated. I searched on the internet and I found that we need to get the eigen frequency of both the models to compare with each other. 3). I have to perform ansys using 5 to 6 materials and choose the optimal material. I am attaching file which contains images of my model

    Control of 3D printer nozzle temperature The hot end of a 3D printer can be seen in the schematic in Figure 1. The nozzle is heated using a heating element, while a thermocouple is used to record the temperature. The hot end uses two cooling fans: the hot end fan and the layer cooling fan, where the blue lines indicate cold air and red lines indicate hot air. A controller is used to maintain the temperature at a constant 200°C. Figure 1: Schematic of 3D printer hot end For the system shown in Figure 1, the layer cooling fan suddenly turns on and the thermocouple temperature drops to 190°C. Part 1: Using a block diagram, sketch out the interactions between the controller, process, and sensor. Define the following: 1. Set point 2. Process variable 3. Control variable 4. Disturbance 5...
