What is CAD / CAM software?
Computer device design. In the reference to software, it is a way of designing and creating geometry and models that can be used in the manufacturing process. Computer Manufacturing. In reference to the software, it is a way to work with the designer part of the model, create tools for different parts, and create an NC program which is then sent to the CNC machine tool to do. CAD and CAM are integrated into one system. CAD / CAM software is also widely referred to as CNC Software as well. Heavily searched words, "CNC Software" will also include PC-based CNC controller software as well. This is where you can change your computer into a controller for your machine that supports up to 6 axis applications. A good example of this is the Mach 3 controller software provided by ArtSoft.
The purpose of CAD / CAM is to automate and streamline CNC programming allowing entrepreneurs, designers, and CNC companies to produce products and market them faster and more economically than ever before. It's the idea of producing products faster … better and easier.
Traditional offset versus High Speed Toolpaths
The term "Toolpath" is used to visualize and describe the way in which the CAM side of the software tells the clip tool to mechanical geometric areas part of the model. It is the way the device takes over when working. Toolpath is basically defined by the part or areas that the user has chosen to machine, the size of the device used, the cutting area for the tools and the type of processing method used. There is the tool whether it be a mill, a router, a laser, a burning machine, a water surface or a CNC lathe. There are a lot of other data included in the creation of NC programs that have to do with processing parameters such as speed and feed prices based on policies, materials and tool data and more. Machine controls may differ in how they want to see the g code for the program to be properly read by the controller. It's a toolbar.
More than one toolbar is usually used to perform machining. Usually this will be "Roughing" and "Finishing" action. Roughing is usually the first stage of machining.
This is where many steps down with the tool, remove the bulk of the material.
The second operation must complete the operation to complete the processing stage. There is also a "halfway". An example of this would be to use the Z-Level Roughing action to remove most of the material. Then, the Z-Level Finishing feature is the "semi-complete" section and finally the "Equi-Distant Offset contour" feature to complete the section. By using a high-speed workshop in your processing, you can achieve outstanding results faster than using traditional versatility tools. Even in the world of 3D processing. The BobCAD-CAM software offers a unique Advanced Roughing feature that includes the ability to use Adaptive High Speed machining technology. This was specially added to give the programmer the option of cultivating a 2D or 3D part or the entire part.
Limits can be created and used to separate workshops in specific areas, deep cavities or areas requiring less tools for machines. This would not be used to replace the REST operation. Advanced REST machining operation would be used as part of the finishing process to clean up areas where larger tools could not be engineered. Traditional versus toolpath has been the most common toolpath image in use since the advent of the CAM software. However, as more and more stores are starting to use HSM, they rely more, become increasingly important and begin to benefit from it. The goal of using a troublesome form of guide is to limit the number of collisions that the device has to cut, reduce chip loading, make better use of the tool itself, using more of it while removing the depth of cut and at a much higher speed.
There is a distinction between tools, planar, offset and high speed (HSM).
Planar (1) is a fundamental of three and is basically back and forth sectioned. Options for this style of toolbar include the ability to machine in one direction (zig) and back and forth (zig-zag). You should also be able to determine the cutting direction (climb or normal), determine the "Snare" variable and step over for the cutter. Some CAM systems will allow you to include side credits and bottom payments so that content can leave to pass. Tablet changes and pipelines are often limited to plunge, ramp or spiral when using this type of policy, each option being defined by input size. In addition, compensation control can be available for the finishing pass. These options include the availability of a complete database of databases / libraries with cradle and tool holder libraries as well as complete database / library content. CAM software is designed to organize these methods and related variables. BobCAD-CAM has developed every machining action in the "wizard" that steps the operator through the procedures so that the attributes are organized and no variables are left. This makes the process easy to understand and get through.
In addition, the CAM allows the software to write on a system modifier so that the operator is not limited. This would include the use, or not, of system tools, tool heights, and offset values, speeds, and feed parameters for the operation. These features should also allow the device to slow down when the circular corner is turned off (when not using HSM).
Offset (2) is the most common in cnc processing of open or closed pockets and slots in 2D / 2.5 Axis (X, Y and Z steps). Very similar planar, this type of action in the CAM system is going to have the same variable input. The difference is where you want to create versus IN or versus. These continuous offsets will either start without working towards the center of a specified area or starting in the middle and earning in the outer wall or defined area.
All of these features in the CAM application will also include one step or multiple step options. This is where the total depth is either automatically calculated from a part of the model or manually input from a developer. Enter the depth of cut and the CAM program should automatically calculate the number of Z-clips needed to work (rough) part of the area.
The motorcycles will usually have many right or left bends where the device can be stopped and operated during processing. The more this happens, the more the wear level will be on the device. Usually, this type of workshop will lead to higher frequencies and will have to spend more on tools for jobs that have cutting designs that minimize heat in the cutting area to reduce energy consumption as well. Offset tooling can lead to higher frequency tooling flexibility, which can also cause parts to be compromised by endurance and poor surface treatment. This means that you cannot use higher speeds and feeds frequently. While versus toolpath can be very useful, there are High Speed toolpath methods that provide the most benefit.
High speed (3) mechanical engineering methods, also known as "Trochoidal" machining tools, open the door to a number of important benefits.
- The controlled cycle creates low cutting strength which enables high axle cutting speeds. Multiple tools can be used to create a high table current with secure tool life. In other words, serious cuts can be achieved.
- All cutting lengths can be used to ensure that heat and wear are uniform and spread and lead to longer tools.
- There is a constant engagement tool, deeper editing and NO stop and go.
- The speed of the toolbar is very good for slots and landing when vibration is a problem.
- Higher speeds are used which lead to better remedies for various factors (reduced deflection tools, vibration / chatter, etc.) During motorcycle times are significantly reduced. Shorter cycle times at work.
Most stores are cutting faster today than they did ten years ago. Albert Einstein said it first and foremost, "All movement is a relative." From that point of view, relative improvements in "ratio" mean that the shop is operating at a high speed compared to what it used to be. Increasing spherical lump speed in tools from 12 to 24 ipm and rpm from 4,000 to 8,000 rpm is a 100 percent increase in cutting speed and well within what is commonly found on most CNC processing plants.
In addition, since the drawer creates a chip, the heat generated by this operation is transferred to the tile. When the tile breaks and leaves the cutting area, the heat is transported with it. A major advantage of high speed processing is that when speed and feed are increased, the tile is cut and transported so fast that it promises to transport little or no heat to the green workpiece. In many cases, this eliminates the need for coolant. At conventional processing speeds, it is time to heat transfer from the chip to the dirty metal and create a work hardening condition.
This increases the power needed to create a chip that creates more heat and so on. Coolant reduces the circulation by decreasing the temperature in the cutting area and flushing the tile away. However, at very high rpm, the tool throws coolant rotation away from the cutting area, so without very high pressure or correction through the device, never reaches the cut area. Trapped tiles can continue in the ditch and allow them to be cut back by the device. Therefore, air blowing is very efficient in speeding up chips at high speed.
High speed machining can certainly help produce equipment more precise parts with better surface treatment. And often, because the hardware and work equipment must be very stiff for high speed processing, the results are consistent with the work area. All of this together consists of greater efficiency in CNC applications, machining and ultimately increased ROI for CNC trading.
WHO HISTORY …
A year ago, at the beginning of NC, each data transfer was executed in sequence, one at a time. The speed was slow enough to be a practical arrangement, especially for drilling and 2D linear grinding operations. It was when the machine had to perform a curve or outline that the need was to see what kind of data was ahead of the program. Otherwise, the machine weight will drop the drawer to shoot down or cut the approximate change in cutting direction and cause destruction of the workpiece. It needs to lead to the development of a look, which is necessary for the great processing of any geometry, except for linear, unidirectional movements. If your CNC controller does not have a lookout feature, it needs updating for high speed machining. In 2013, there are many cost-effective solutions to this, such as Mach3 by Artsoft, which can help launch older machines.
Taking a high speed way to CNC profitability
We really don't see a training book specifically about high speed machining and CAD / CAM together. However, CAD / CAM software is an absolute necessity for the creation of these types of processes. Without CAD-CAM software, they would not exist today. The benefits listed in this article describe all the reasons why stores should take advantage of this technology. And now, for the first time, high-speed adaptive production systems available through the BobCAD-CAM for Multiaxis CNC machining open the door for even more complex CNC work to take advantage of its powerful capabilities and profitability. Engine Time is money and lowering of cycle times that lead to faster spin, happier customers, better performance, lower cost and longer life for your CNC hardware, all equal profits and better business practices.
