I want to create an automation for creating holes & and threading on cylindrical metal.
To be specific 3-11mm hole and M4-12 thread on cylinder metal. (Thread - Drill & Tap Chart)
I’m a computer engineer and I already have some experience with arduino and basic electronics, and there are enough info on the net about how to control those motors. I also found about info for the speed needed for drilling / tapping and moving speed for the drilling / threading motor for different holes/threads. But I dont know how much power I will need for motors, and I also dont know how to create more effective product feed. I plan to get 2000 products a day (8 hours) from this automation (About one product in 15 seconds) .
I planned to have powerful step motor as Z axis motion control for two motors putted on the mount, one for drilling and one for tapping. The Y axis will have two mill rods for holding cylindrical metal product and one linear actuator for moving position of the product on the Y axis.
Motor 1 ) For motion control, I decided to use Leadshine M452 for step motor control and I plan to use this motor http://www.exoror.com/datasheet/86BHH114-450p-40Mp.pdf (Holding torque 62kg.cm).
Question 1) Should I use more lower or higher torque motor? Is this right choice for this task. (Holding two motors, and pushing those motors for drilling (in terms of torque), tapping (in terms of precision).
**Motor 2 )**For drilling hole motor & thread motor I don’t know what to use.
I’m thinking about to use drill motor for drilling hole because it has adjustment for speed between 3000rpm and down. And its documents says, it can create 12mm hole on metal. (Bosch PSB 650 RE)
Question 2) Can I use another motor which can be controlled with a polulu 2A step motor driver? What kind of motor I need to use? Or should I use something like Motor 1?
Motor 3) For tapping-threading, I decide to use more low rpm screwdriver motor, something similar to this Error 404 | Bosch Global
Question 3) Can I use another motor which can be controlled with a polulu 2A step motor driver? What kind of motor I need to use?
Motor 4) I think a linear actuator motor can do this task. This will move the product from position A(product feed) to B (drilling) and C (threading) . I mean this kind of motor http://goo.gl/zPzG6p
Question 4) Should I use ball screw and stepper motor for this product positioning or can I trust a linear actuator motor?
Product Feed & Motor 5 I thought about lining the products on vertical line, as the product only has 7mm diameter, I can put 100 products on 70cm length. Actually I had no idea about this product feeding mechanism. I thought about I take one product from bottom by pushing the product on the bottom with linear actuator motor, but I dont know whether this system will work without problem.
Question 5) Should I use a motor which will push the product on the bottom to Y axis (where products move)?
Question 6) Will I need cooling system(pumping motor for oil or water continuously) for drilling & tapping motors?
