 There are two basic options for controlling the operation of a CNC milling machine either through a computer or through a DSP controller. In this video, we will compare these two methods so you can choose the best one. You're on the Watson channel. Let's get started. Let's start by looking at the pros and cons of working on the milling machine via computer. Watson has been designing and building CNC machines for over 20 years, and among all the options, we choose NC Studio as the best, most modern, functional, user-friendly, and simple-to-use solution. NC Studio is a hardware and software complex, which consists of a decoupling board, which is installed in the machine-controlled unit housing, as well as a PCI interface board, which has its own microprocessor and is connected to the motherboard of a Windows-based computer. In addition to the hardware part, there is also a software shell of the same name with a convenient graphical interface. Advantages of NC Studio First of all, NC Studio is user-friendly and easy to learn even for beginners. The clear interface of the program makes it easy to store and search for files and make various settings. The system is compatible with 3D modeling and layout programs such as Artcam, SolidWorks, Type 3, and others. In this way, all information including feeds, tool information, and other settings can be transferred from these programs. NC Studio efficiently processes control programs with an unlimited number of lines of code. Before starting, you can run a simulation of the processing process, which will help you find potential errors and correct them. The NC Studio hardware and software system has an analog output for infinitely variable spindle speed control. Disadvantages of the NC Studio system NC Studio is only suitable for 3-axis operation plus a rotary axis. Most of the time, this is sufficient for working on a CNC milling machine. When controlling the machine via NC Studio, the speed of the machine is limited. Static electricity can damage the electronic components of the computer, so grounding is required. NC Studio requires a separate PC with a 32-bit Windows 7 or Windows XP operating system. A laptop is not suitable for this work. It is strongly recommended not to install any other applications than NC Studio on the job computer in order to avoid possible errors during operation. In this way, the computer completely belongs to the machine and becomes part of it. Further, a separate place in the workshop is required for the computer. Besides, you should take into account that during the work, CNC milling machine generates a lot of dust in other small particles that will slowly but surely destroy your computer, especially if you work with stone or graphite. To solve this problem, you can use the aspiration system of the machine and protect the computer from dust as much as possible. Equip it with filters and ensure the tightness of the case. Now, let's discuss the DSP controller. It's a small wired machine remote control that fits in your hand. It comes with a decoupling board which is installed in the machine's control box. It has a keyboard and LCD screen. All manipulations are done by pressing buttons or a combination of buttons. Advantages of the DSP remote control The remote control is quite easy to learn and practical to use. It's quite mobile and convenient to work with. In addition, it doesn't require a separate workplace for installing a computer. You don't need a separate computer for the machine control system at all. Ready control files can be loaded via USB drive into the non-volatile memory of the DSP controller. Remember that you still need a separate computer to create control-programmed files, as well as in the case of NC Studio. It supports all standard G-code, F-code, M-code, PLT graphic instructions and understands most CAM systems, such as Type 3, ART CAM, Master CAM and others. You can change the machining parameters during operation. In the event of a sudden power failure or power surge, the DSP remote will save the process information and allow you to continue the process from the point where it was interrupted. The DSP controller works easily and quickly with a large volume of downloadable programs and does not need periodic updates. It is more stable than NC Studio, as it has less probability of errors during operation. It is not subject to viruses or system failures with its subsequent reinstallation or updating. In addition, DSP controller is not afraid of dust. The cost of DSP controller is lower than the total cost of NC Studio, taking into account the purchase of a separate computer and arrangement of the workplace. Disadvantages of the DSP controller Compared to NC Studio, it's a little limited in the file formats it can work with. It's afraid of bumps and fall. When working with DSP, there is no visualization of work processes. But visualization can also be done in the CAM system in which you develop the layout for machining. According to our practice, it is more convenient and pleasant to work with a DSP controller. What to choose in the end? Ideally, what is most suitable for you? To find out, sign up for an online demo where we'll answer any questions you have and show you the process of working on a milling machine with NC Studio and a DSP controller. So, you can compare them and choose the best one for you. You've been on the Watson Channel. See you in the new videos!
