Introduction & Overview (0:00-0:34)

0:00-0:34: “Hello. Hello. Welcome back to another training video. In this section of videos we’re gonna be talking about machine orientation, things like safety and protocols that we can follow, the machine orientation, the workstations and axes as well as the interface and understanding the layout of the controller interface. So all of these will be broken into separate videos. In this video, we’re gonna focus specifically on the safety protocols that we need to follow when we’re around or using the equipment. Now being in a woodworking environment, and you can also cut other materials”

Personal Protective Equipment (0:34-1:02)

0:33-1:02: “and you can also cut other materials besides wood with this, with this machine. Um, we need to protect ourselves such as our eyes, our ears, and our lungs from any harmful situations. So get some safety goggles, get some ear protection, whether it be plugs or muffs completely up to you. And make sure to have a qualified dust mask. Um, different materials, obviously most materials will be re um, producing some form of dust and chips. However, there are certain materials”

Operating Safety Practices (1:02-3:09)

1:00-3:09: “However, there are certain materials that will even produce fumes that, uh, come off of, come off of the material. So make sure that your filtration system and your dust mask can handle whatever materials that you’re planning to cut with the machine. Okay? So get your gear ready and wear that whenever you’re operating or around the machine so that you don’t have any harmful situations happening to your bodies. On top of using the safety gear that we need, we also need to pay attention to two practices that we need to follow when operating and using the machine. Now the machine is gonna be in really two different stages. It’s either gonna be stationary or mobile. Okay? Not moving or moving. Those are the only two modes that the machine can be in really. Um, and so we need to make sure that we can pay attention to those situations whenever we’re interacting with the machine. So within the work envelope of the machine where the cutter can get access to our material, um, we need to make sure the machine is always at a stopped position whenever we are reaching into this work envelope. Okay? So if there’s any movement happening with the machine whatsoever, we do not want to be any part of this work area whatsoever, okay? In other words, we want to stay, keep some distance away from the machine as it is doing its job. And then when it comes to a stationary stop, whether if it’s done with a program or performing a manual tool change or whatever situation happens and it comes to a stopping position, then we can approach the work area, um, during that again, holding time. Okay? So that’s the first point is just stay away from the machine mechanically. And we have decal stickers throughout the machine that will warn you of pinch points and areas that can cause harm. And so this is, again, just following that rule, is anytime the machine is moving, just keep your distance and don’t go within that work envelope. Um, a lot of people even create, uh, either taped off areas yellow Tape to say, okay, if you are coming to the machine, you’re not allowed to get within this, you know, this distance between the platform as it is operational, um, and then only qualified people that have been trained”

Tool Change Protocols (3:09-4:02)

3:07-4:03: “and then only qualified people that have been trained to use the machine can actually approach the work envelope, um, in order to again, interact with it and use the equipment. So manage this however you wish. Now the second thing we need to practice for safety is how we’re interacting with the spindle, okay? ’cause the cutter is gonna be rotating at higher RPMs and those are sharp tooling and that can cause a lot of damage really fast. And so we want to make sure we’re following the right protocols whenever we are taking cutters in and out the machine, specifically during a manual tool change sequence. Okay? So here’s what we always do. Same, same thing. We’re never going to be actually, um, reaching or putting our hand towards the cutter to perform a tool change unless there’s two things that we need to verify. First is the machine has come to a stopping position, okay? And usually it’s gonna be coming here to the operator to perform a tool change for manual tool change situations. And we’ll get into greater details on that when we actually,”

Emergency Procedures (4:02-5:00)

4:01-5:01: “And we’ll get into greater details on that when we actually, um, show you how to do that. But that’s the first thing we’re gonna verify. The second thing is we always want to make sure our dust shoe can be opened. So if it’s like this, I need to open this dust shoe so that I can visually verify that the cutter has stopped rotating before I perform that tool change sequence. Okay? Um, and those are really the two things we need to verify to make sure we don’t have any of those accidents with the tooling whenever it is going to be, um, uh, prompting us to perform that manual tool change. Okay? So yeah, so with the spindle and the manual mo motion, we can follow those two practices of safety. Now the last note on safety is just knowing how to turn off the machine. Um, it’s one thing to know how to operate and run the machine, but the most important thing is to tell it to stop when you need it to. Okay? And that is using the emergency stop switch here at the controller and lemme show you where that’s at. So here at the controller, um, on the left side”

Conclusion (5:00-5:42)

4:59-5:42: “So here at the controller, um, on the left side of the machine, we have our keyboard mouse controller, and the bottom left corner is our emergency stop switch. And that can be pressed in at any time to stop the machine during any procedure. Again, as a quick overview, use your safety gear, stay away from the machine as it is moving. Um, never reach your hand towards the cutter, um, to, um, in a tool change unless you verify that it is at a stop position and the cutter has completely stopped and you use your emergency stop button if you need to stop the machine at any given time. If you follow these practices, um, you are well on your way to keeping yourself safe while using the machine and producing some amazing projects. So we’ll see you guys in the next video. Thank you for watching.”
