What is the effect of the depth of field

Explanation: not surprisingly, the benefits is to increase the pixel density can improve the accuracy, although it is a price, the price of it is a larger data file size and longer time to scan. In carefully designed experiments, the ability to accurately measure dimensions in a numerical control scanner is optimized, which is superior to plus or minus 0.001.

Let’s look at figure 16 below. Fpc2 scan precision verification data.

What is the effect of the depth of field?

For image collection, we use a 10% view, and our series of scans is collected from 2.5 d geometry. After each scan, the camera refocuses, and it typically focuses on a new focal plane. Then, in each of the results, the same round features were measured. The relationship between the measurement of diameter measured on the plane and the distance of the focal plane is shown in figure 17.

Explanation: if it is within a small field of vision, fpc2 scanner as a telecentric lens simulation is there, it’s performance has been pretty steady, in this case, the “change” in the depth of the focal plane 0.300 shown in less than 0.002 “change”.

What is the source of the error?

In these measurements, we can see there are a number of error sources, including some of the error and the error is introduced in choosing a distance, and the error is in the scanner fpc3 measurement. The responsibility of the user is to explain the exact location of the edges based on the contrast of pixels. System error is introduced from the limitation of fpc4 positioning repeatability. We know that fpc5 minimum discrete positioning movement 0.0001 “; Shaft drive, however, the influence of other factors in the system (precision ball screw, friction, wind, etc.) are we considered, so we need know positioning repeatability of 0.001 “, or better, decided it was in the fpc2 scanner from introducing a single optical mechanical error. Like any microscope, if you are in the fpc2 scanners used in optical instruments, can lead to something about the image distortion, this situation is caused by some lens distortion, at the same time, can also affect the curvature of field effect.

The basic description of operations

At this point, it’s a double-edged sword, for design engineers. When a new product into the market, it also began to feedback, “I hope they like what we do”, this has always been very optimistic that the designer, but at the same time will also feel uneasy, worried about “damn, I should think about it”, the idea will come from user feedback, of course, this is as part of the process.

The basic description of operations.

What did the fpc2 scanner do? It assembles a size of fpc8 from a series of photos that are stitched together. A primary axis installation of adjustable focus USB micro camera features is used, and fpc9 is also used to quickly change the installation system.

It can be seen that the camera’s precise positioning of the mill’s CNC actions can be precisely done by the camera, no matter which photo is taken. To complete this step is to pass a software plug-in based on the fpc9 movement control program. So who decides the exact location and number of photos? It depends on the desired size and resolution, and the fpc2 scanner software algorithm can determine it.

What determines the size of the image? It is a decision in two ways. The first is the traditional method of placing the known dimensions in the field of view, so that the scale can be determined — this is essentially the reticular approach that has been discussed. The second way we know it is unique to a numerical control scanner. The control motion of the mill itself is used by it. By making the position change of a certain point can be calibrated, the actual distance of the mill can be determined.

After assembling the fpc6, if you want to open it, can open it in CAD fpc8 scanning, the 2 d CAD program is very simple, the basic function of measuring distance and tracking shapes is it has. This information can be exported and exported as an industry standard. Fpc8 files can also be used on other fpc9 programs, which are intended for further work

What is the content of the project discussion

Here’s another example, courtesy of Ryan Kennedy. Because fpc2 scanner being taken advantage of, so, fpc7 rifle tank hole size and location can be recreated, and the output, and can also be further work, to export it to a solid modeling system.

Manufacturing tolerance is verified, small operation/custom production

We made a small part of the customer for the customer. The fpc1 scanner is used so that we can measure each part so that it meets the customer requirements of the size tolerance and can be verified.

We can look at figure 4. The key dimensions of the parts are verified by fpc2 scanner within the tolerance range.

How to fix it? NORTON’s rocker arm. It is very hard to find old components, such as fpc7, as shown in figure 5. We can use the fpc7 scanner to capture information about the key geometry, for example, the length and Angle between the arm shaft center and the CAM and valve connections can be measured using fpc7. Then, we use this information to allow a template to be recreated to replicate the original widget or machine, which is a new replacement component for saving functionality.

Let’s look at figure 5. We can determine the geometry of the rocker arm, from an old-style NORTON commando.

What is the content of the project discussion?

It’s not necessary to the understanding of the following discussion, which is for fpc2 scanner operation discussion, though, to understand its characteristics and development of realistic expectations are helpful.

What are the resolution limits for digital cameras?

We all know that anyone who buys a digital camera has the experience of solving problems. The resolution of fpc8 is represented by megapixels – if a fpc8 produces a 1280×1024 pixel image, its resolution is about 1.3 megapixels. Finally, a feature of the image sensor is resolution.

What is reverse engineering

We have an example application here.

First, what is a manufacturing tool? The fpc1 electrode used for jet turbines is the manufacturing tool

In this example, the role of the fpc1 scanner is to reconstruct the outline of the turbine blades, as shown in figure 1 below. Making a fpc1 electrode is required by the precise outline of fpc2, and its purpose is to reprocess a stator, which is mainly used by the jet engine repair. Previously, the work was done by using an electronic probe to collect two-dimensional point clouds, but the process was time-consuming and labor-intensive.

Let’s take an example, fpc3, carbon tool.

See figure 1. If you want to accurately reproduce the perimeter of the turbine cross section, you can achieve this by tracking the fpc1 scanner.

What is reverse engineering? That’s what we call the mechanical clock movement.

One of the features of fpc4 is that it has a difficult shape to measure. Using the fpc1 scanner, we can design these shapes by tracing the outline shown in figure 2. The technology can also be applied to CAM mechanisms and other complex mechanical shapes.

Let’s look at figure 2. Our fpc5 reproduces the clock movement and USES the fpc2 scanner.

Damaged parts need to be rebuilt: FPC rifle air gun.

On fpc5 rifles, installed in the barrel diameter is around air rifle, and a gas pipe was also supported, the gas tube after launch, can also be some gas separation from the barrel, the ignition device can be reset. Because the fpc2 scanner is adopted, the hole diameter and center spacing can be accurately reproduced. The size graph is then exported to fpc6, allowing the remanufacturing sequence to be designed.
