What are the engineering challenges of the fpc2 scanner

Its ability to measure is innovative – although there is no shortage of available measurement tools, no solution is a perfect solution for measuring difficult shapes. If the original size mark is not available, what role would it be to recreate these shapes? It can prove that this is a tedious or impossible task. There are countless examples of this, such as watching mechanisms, carvings and complex curves. Generally speaking, even with the improvement of the affordable 3 d scans, its accuracy is often limited, and generally, it is limited to plus or minus 0.005. For many, the results are clearly not good enough.

Expensive optics are designed to be used by inexpensive industrial metering systems, and for small shops that require only occasional use of the technology, this is unlikely to happen. What are the engineering challenges of the fpc2 scanner? It is a tool that can measure both fpc2 components and can afford expensive prices.

As we all know, the universal fpc2 scanner’s control plug-in is universal, and most fpc5 cameras and standard CNC scanner software can be supported by it. Tomah’s open architecture philosophy we have to insist on, especially the changing environment of consumer electronics products that we consider.

Being able to do fpc6 reverse engineering – developing an independent CAD program is not our goal. There are already many good companies that have done better than us, and they are cheaper and better on anything that can be offered. Simply create a fpc7 environment is our requirements, and also can implement a simple measuring and drawing tools, fpc7 can be imported, and enough function can be used to measure and features. In industry standards, this can be exported. DXF format, if necessary, can be further processed in the fpc8 selected by the user.

Designed for the occasional user is an easy-to-use fpc2 scanner. Obviously, for operations, it must be easy to learn and easy to use.

This will be very convenient for all users, so this is also our goal. In order to achieve this goal, it is more convenient and more useful for users to use, so we will make unremitting efforts.

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.

traditional machining center-ball nut,slightly larger ball

The basic precision of motion is rated by us. For P applications, both the incremental and cumulative precision are very important. In the T/C application, only incremental precision is specified. We can talk about this as an example:

There are 12 errors that can be allowed within 300mm of fpc8. If it’s in empire, it’s about 0.0005 inches per foot. What’s the cumulative error? It is about 900 mm, and is limited to 21 um(0.0008 “35”).

In terms of cost, the cost of fpc9 is relatively low, and it is often used to transform or refit the manual machine. Screws can be made by rolling rather than grinding because of low tolerance.

We set for fpc2 design rules, the rules of the design allows a lower speed than traditional machining center and less of spindle power, but we think on accuracy, they must be the same. This point has been taken into consideration by us, and fpc2 fpc4 level is our choice.

The screw is only half the problem; The other half of the problem is the ball nut. A standard ball nut will be free to move in a one-thousandth chance, which will cause a considerable rebound to occur on the screw. What does fpc8 do? It can be used to prevent this from happening.

There are two ways to make fpc8 nuts:

First, the oversized ball. Make fpc8, you can use a slightly larger ball and then make it tight. It’s a manual process, of course: someone can only put one ball at a time, the rotating torque needs to be checked, and then put on the next ball. When preloading is set, the manual assembly process is needed. We are against nuts. This allows two complete nuts to be involved. Between them, this fpc2 will have a precise ground spacing to make an offset be forced. The thickness of the gasket determines the preload.

overall machine-labor requirements,filled acetyl groups

When we need to apply a force on sliding, machine parts will be like a spring a little deformation will occur, until can overcome static friction, to overcome the static friction need to have enough strength. When we overcome static friction, the power friction takes over, and the energy of compression can be converted into motion. The result is a slippage/adhesion phenomenon, and sometimes we call it a sticky phenomenon. The intermittent games are caused if you move heavy objects with very slow motion; In the worst case of machining, chatter in the form of it. Since the static and dynamic coefficients of the polytetrafluoroethylene filled acetyl groups are also very similar, the vibrations are almost absent. This can improve the accuracy of the overall machine.

The polymer surfaces are formed by gluing on a thin layer of material, usually about 0.031 inches. This material is usually relatively cheap in terms of price, but it is a time-consuming process in terms of time, requiring very skilled labor requirements. One of its drawbacks, therefore, is that, as with chromium plating, the way their polymers float on the surface of the water is expensive.

Now the way of sliding is generally replaced by linear bearings for most designers of machine tools. For example, ball bearings, linear bearings are used not by sliding mode but by rolling contact. While it may be more expensive to watch on the price tag, some unique advantages are offered. First, from the installation, they are easier to install. In linear bearing assembly, there are not many skilled workers involved in bolting connections. Perhaps the low force required for high-speed motion is the most important characteristic of linear bearings.

Now let’s look at the details of the main axis

As the bullet passes through the head, it enters a tight hole and a 6-bolt flange connection is passed by it. Of course, there are several advantages to seeing this structure:

The lathe turns the body with the lathe to turn the valve body, so that the separation of the concentricity and the main shaft nose Cartridge can be ensured. This makes on the workbench to replace bearing is allowed, if you don’t want to replace the bearing, also need not in the machine, your cartridge can be shipped back Tarmac, back to the cartridge is used to reassemble the new cartridges, easy machine modification is allowed. When the cartridge is removed, the head can easily install anything, such as what the manufacturing engineer might have dreamed of. A fpc3 can be used at this time, and a fpc4 can be used instead of a 4,000-rpm spindle motor or EDM system. What would you think?

Now let’s look at the details of the main axis.

A fpc7 is owned by almost all small craft workshops. A steeper 7/24 taper (3.5 inches) is the most common fpc5, such as fpc4 and fpc6 cones. 7/24 tooling is more rigid than fpc7, and higher power can be allowed. This feature is very important because the fpc1 processing center often sends 15 to 50 HP or more through the tool rack. It is not appropriate for a fpc7 to transport 15 HP to an end mill.

The common 7/24 tool is only on the cone when touching the spindle. Some double-sided vertebral bodies have been produced by recent innovations, both of which are in contact with the main shaft of the two kinds of taper and flange tool supports. The fpc5 cone in Europe is included in the fpc6 double face of Japan, and the fpc6 double face is included in it. More hard support and better repeatability are provided by double-contact or two-sided systems at height.

cutting tools-hydrodynamic forces,end grinder

We used similar principles when we were working. When cutting tools are cut, they can be compared to bullets in jars. They are similar. If the inertia and viscosity of the air are compared to the viscosity of the oil film, the damping performance of the cast iron and the overall quality of the system, they are similar. In these applications, the damping of hydrodynamic forces is superior to that of linear bearings, and the iron is more optimized than aluminum.

Both quality and strength are important, but there is a premise that they must be in the right place. Iron is best used when used in the chain of components that grind from the end to the workpiece. If you’re working with only 1,000 pounds of iron, then it’s very pointless to invest a lot of iron on a supportive basis.

What are the operating parameters for dynamic stiffness? It includes cutting the highest possible surface speed and using relatively light cutting depth. Now, we all know that there’s going to be smaller cutting tools and a higher spinning speed. The coolant requires one of the indirect impact design parameters. If the highest surface velocity wants to be kept by you, then the essential one is the coolant. If you have a mill, it’s about 8,000 pounds, so it makes sense to use a high-end pulverized and speed at 500 RPM. If your grinding weight is very light, then you’d better use a smaller end grinder to keep your speed up this point can be maintained.

What is the KISS principle? In layman’s terms, keep it simple, stupid.

Low cost, long-term value, and reduced maintenance are all due to simple and solid structures. That’s for sure. During the design of fpc2, our guiding thoughts were always KISS.

production machine-milling machine,automatic tool

However, if it is in prototype development, it is only a small part of the runtime, and for setting the time, it is the extra time that is irrelevant. And what’s the most relevant? The most relevant is the cost savings that the design provides.

Obviously, in a short period of time, both the precision of the machine and production machine, they are the same important, but in a short period of time, not important spindle power, speed, and the demand of the automatic tool change.

On light machines, we need to achieve precision. What kind of milling machine is considered too light? In general, we believe that the weight of any of the milling machines below 5,000 pounds is very light. If you want to achieve precision, you can implement it with a lightweight machine, but some of the necessary features must be remembered. Dynamic stiffness is one of the most important considerations.

The ability of a machine to resist external forces when moving is dynamic stiffness. What determines the degree of dynamic stiffness of a machine? Generally, it depends on a number of factors: speed, inertia, static stiffness, and damping, for example. For example, you can imagine a quarter of a diameter rod round head; At this point, imagine trying to push that blunt bar over an empty aluminum can. You can make some sounds in the process and crunch as you can get through the can. Now, we use the same aluminum can, place it on the fence post, then shoot it and shoot it with a 22-caliber bullet. At this point, you get a hole, and the hole is a clean, unreformed hole. We all know that the force is sometimes weaker than the static force, but it’s not the same as the dynamic force, and it gets very hard. The result of dynamic stiffness is cleaner cutting.

What are the application features that we’re talking about

What are the application features that we’re talking about?

Why we want to create a personal fpc1, its goal is to provide a fpc1 factory, so that the needs of the short-term application can be met to the lowest possible cost. Whether it’s research and development, entrepreneurship, education, or amateurs, they all need a machine that can easily and economically operate in a short time. In order for us to understand the design implications of the short run, we’ll make a comparison between the application and the more traditional application.

The time for the machine to cut the newly designed parts is usually a few hours, but for the cutting process itself, the traditional machine may be needed for only 10 minutes. If it is a traditional small fpc1, its main shaft may have five horsepower to 7.5 horsepower. If the main power supply is down, you probably down to closer to the classical Bridgeport factory, which is between 1 to 1.5 horsepower HP, then runtime will change, there are about 14 minutes. In addition, how fast is the traditional mill? It’s about 200 inches (IPM) per minute. If rapids is also reduced, if it reduces to 65 IPM, then the running time will also change, and the running time will increase, probably to 16 minutes. If, in the absence of automatic replacement tools, only quick replacement of the manual system, the running time can also increase, increasing the time by about 2 minutes. The result is this. The running time is 18 minutes, not 10 minutes. We all know that the difference is trivial in the time frame required for design, installation, fixtures, and code development. We know that if it’s a 1.5-horsepower fpc1 factory, it has about 65 IPM rapids, and what’s the funny thing about it? It is in a production environment that there is no tool change, so every minute of it can be said to be critical.

multi-speed transmission-plastic, aluminum, iron, steel and stainless steel

After the first generation of products, the best of the five products were chosen by us, we focused on a machine, and we built our cooperation with just one company. Then another series of designs builds, and test cycles were started again. Before the final design was put into production, our design was improved, and it was improved by four machines.

It is basic parameters.

Use our fpc1 (plastic, aluminum, iron, steel and stainless steel) may reduce the dynamic stiffness of this material are considered, so we came to the conclusion, what is the best speed range fpc2? Its best speed range is around 300 to 4500 RPM. As you all know, because we design is a short run, prototype production, and education, 1.5 HP enough spindle power is determined by our, but, 65 IPM is to belong to the speed of the machine movement. It is essential to note that coolant, the standard feature of the coolant control machine, is the decision we make.

Once, providing variable speed as an optional upgrade was also considered. However, if this is a cost-effective upgrade, its foundation should be a simple addition, not a reconfiguration, and it needs to be carefully choreographed. If only a variable speed fpc6 was added, this would be a good solution. In reality, what will be included in the machine that is designed for manual speed change? Includes a single-phase motor and a multi-speed transmission. If you want to upgrade to a variable speed, a three-phase motor will replace the single-phase motor here, with the goal of increasing fpc5 drivers. After the transformation, a complex multi-speed transmission is left behind by the machine, which is completely unnecessary. It should be part of the basic machine design that we decide, instead of providing variable speed, and then using variable speed as an upgrade.

What are the application features-standard control computer

Modular design with module design and industry standard interfaces are what open architecture means. At the same time, the open architecture also means that we should fully disclose the nature of the indirect port of the internal module. How do we apply the concept of open architecture?

It includes the content, the first is the industry standard control computer, which is our PC and Windows operating system, the second is the standard fpc2 code language, also is the knife we said site, the third is the standard drawings and image files, and support the industry standard machine d fpc4 shaped groove, fpc5 spindle taper, fpc6 spindle nose, in addition, also including the motor, here are divided into shaft motor and spindle motor, at the same time, the PC printer port is fpc5 standard internal electrical interface – PC interface.

We want to know why these things are important.

If want to become to the machine is easy to maintain, will need to use the common tools and auxiliary machinery, if you are not specially trained personal service, then the machine manufacturers will not risk you as replacement parts. It is also very easy for machines to modify or consolidate into larger manufacturing systems.

What are the application features?

Providing a fpc1 factory is our goal to create a personal fpc1, with the aim of making short-term application needs very satisfying at the lowest possible cost. Whether it’s research and development, entrepreneurship, education, or hobbyist, they need a machine that can easily and economically operate in a short time. In order to make the short run design meaning well understood, we can compare this application with a more traditional application.

What is open architecture? And what does it mean for us?

In these three years, five unique machines have been designed by us, and we work with five different manufacturers. The original selection of the manufacturer was also chosen after a selection of meetings and discussions with dozens of interested companies.
