CNCBase for intelitek CNC is developed by intelitek, Inc.. The most popular versions of this product among our users are: 4.0, 4.3 and 5.3. The names of program executable files are iCNCConfig.exe, Mill.exe. The product will soon be reviewed by our informers.
Our task this week is to design a 3D mold, machine it and then cast parts from the mold. Since I would like to build a robotic arm for my final project, at first I was planning to cast a spare part of it. But later I found the structure is hard to be machined, so I decided to just cast something simple in order to go through the whole molding and casting process as well as leave more time for me to focus on starting with my final project. Thus I designed a one side mold with a set of two gears and a base, which ideally could be assembled and played with after casting.
MasterCam
In our session we use Interlitek to machine the wax which is 6"x3"x1.5" in size. The TA has set up a Mastercam template for us with the rough parallel and finish toolpath, which would save us a lot efforts and time. Thank you Max!
A collision happened immediately in my first simulation of the finish toolpath because the end mill is going too deep and the holder is hitting on the edge of the wax. So I modified the positive mold design, left the base check level up. Then the Mastercam simulator went perfect so I exported the .NC files for the two toolpaths separately. At that moment I did not notice that I missed an important step which would lead to a disastrous result later at the machining step.
Second Board The steps to use intelitek are not complicated after watching the TA go through them once:
        1.Hot glue the wax on the spoilboard (just for this week, there are other tools for fixing the materials if we are going to use the intelitek for other works)
        2.Select the tool (end mill) I am going to use and install it in machine (for this work it is #6 3/8" flat and #1 1/8" ball)
        3.Set zero for X, Y and Z using the control panel in software CNCBase
        4.Open my GCode file
        5.Start and run
It worked well during the rough path, except for the end mill spinning above the wax and ran like that without cutting any wax. I stopped the machine and reset the Z zero but it still had the same problem. After checking the Mastercam I found it showed in the simulated path so I did not need to worry about my previous Z zero settings.
Nightmares started from the finishing path. After I changed the tool and reset the Z zero, the system showed "Spindle Fault Detected" when I clicked run. So I reset everything again from the beginning but it didn't work. Then I reopened my rough path GCode file and do the same setting as the first time, the "Spindle Fault Detected" was still there so I think maybe it's the problem of the machine. Finally it was solved by turning off the Intelitek controller power and re-activating the machine.
When the machine finally started to mill, I found the spinning speed is not as fast as I expected, so I turned to the screen and was about to try adjust it. At that moment I heard a crack sound so I stopped the machine again. This time I broke the #1 1/8" end mill. (I'm really sorry!!!) The cutting part was stuck inside the wax so it should be caused by a collision at the shank part. This confused me since there was no collision warning in the Mastercam simulation. Then I turned back to Mastercam to check through all steps and found the mistake I've made: I forgot to check shank and shoulder for the collision checking in the simulator, you need to check them yourself otherwise the simulator will only check the holder and cutting length.
The BenchMill 6000 is a versatile PC-based benchtop CNC machining center that enables you to deliver robust instruction in computer numerical control and advanced manufacturing for your students. The BenchMill 6000 comes equipped with ethernet-based motion control, 3-axis stepper motors, ball screws, a variable speed spindle motor, and ISO20 taper tooling. This CNC system requires no assembly, arriving at your facility ready to run on an ethernet port on a standard PC, and fits comfortably into any classroom, without sacrificing features. BenchMill 6000 CNC Machining Center Machine shown with optional jog pendant and 4-tool ATC. PC not included. Like larger industrial machines, the BenchMill 6000 uses EIA, ISO, and Fanuc-compatible G&M code programs to cut parts in a variety of materials. intelitek's CNCBase control software is easy to learn. The user-friendly control software supports linear, circular, and helical interpolation, multiple tool programming, and canned cycles. This standard software gives users the ability to write and edit standard G&M code programs and geographically view the machining operation on-screen before cutting. With available supplements like CNCMotion full 3-D virtual simulation software, Fanuc control software, Fanuc hardware emulator and intelitek's LearnMate e-learning curriculum specific to the machine, the BenchMill 6000 is the perfect classroom solution, with exceptional ease-of-use, safety features and reliability. w w w . i n t e l i t e k . c o m
I used a pair of HB-25s to power my Arlo based robot. The robot would consistently drive the exact distance by using the HB-25s along with the quadrature encoders (here's a related post with video). I found it easier to get the robot to travel the exact number of encoder ticks than when attempting to use a MC33926 h-bridge board. The MC33926 is another motor controller which is superior to the L298N. The main thing the L298N has going for it, is it's cheap. The L298N is very inefficient. The chips convert a lot of the power to heat rather than movement in the motor.
As part of the Engineering and STEM Academy, students enrolled in the 4-year PLTW curriculum start the first year with Introduction to Design (ID). In the second year they take Principles of Engineering (POE) and then in the third and fourth years, students study Computer Integrated Manufacturing and Engineering Design and Development, which is based heavily Intelitek curriculum and equipment.
The one-year Robotics program focuses on careers that will build a knowledge base and technical skills in industry fields with a robotic or drone component such as an Advanced Manufacturing Technician, Computer-Controlled Machine Tool Operators, Electro-Mechanical Technician, Electrical Engineer, Mechanical Engineer, Drone Operator/Programmer. The Robotic curriculum follows the Intelitek curriculum which includes VEX Programming, Advanced Programming and Advanced Mechanics. In addition, the Unmanned Aerial Systems (UAS) curriculum provides industry-leading classroom training and prepares drone pilots for the Part 107 Drone License exam. The coursework is taught in an industry setting, providing students with hands-on experience.
