Table: axis x

[TatianaResend]

Regarding the X axis, you can opt for a linear axis solution with a worm or for a rotary axis and work with polar coordinates.

• If it is a linear axis in X, although the machine must be wider, the minimum width is 500mm, it is still not enough to accumulate the YZ engines horizontally without increasing the width of the machine.
• If the shaft is rotary, with a vertical shaft, probably the solution with vertical motors can be more compact.

To use a spindle of this type, the motor needs to be “in front” of the spindle, which makes the system less compact. To put the motor in the opposite position would require a transmission system that would complicate the system. It is also possible to place the motor on its side (compact system) using a 90 degree transmission system (2nd figure)

Types linear motion control:

• ball-screw drives
• lead-screw drives
• belt drives

Additional specification when considering linear motion control design:

• force
• speed
• travel distance
• accuracy
• repeatability
• lifetime requirements or the duty cycle

Notes:

• Ball screw generally have lower speed than belt drives
• Ball screw actuators use ball bearings and are more expensive but provice less friction compared with lead-screw actuators
• Ball screw linear motion drives have relatively high thrust capacity
• Ball screw drive combine repeatable motion and stiff system that handles high forces and moments. Such systems work well in precision-positioning applications with high loads and high duty cycles.

Belt drives vs Ball-screw:

• Belt drives are quiet and good for high-throughput, lower-precision applications.
• More-expensive ball-screw drives provide high efficiency, accuracy, and stiffness.

Control the movement of linear actuators

I have two approaches:

• One motor for each linear actuator: simple in terms of mechanical design, more complicated in terms of automation design because it is more complicated to synchronize both actuators and more expensive because it uses two motors.
• One motor for the two linear actuators: a little more complicated in terms of mechanical design, simpler in terms of automation design and cheaper.

[TatianaResend]

Calculations for validating the use of belt:

[TatianaResend]

Understand the advantages and disadvantages of using one or two motors, taking into account that initially it is intended to use two motors.

The decision depends on whether to use the motor with the brake on the Z axis.

[TatianaResend]

Need to do:

• X-axis: decide whether one or two motors
• Fixing the table and the linear actuator

[TatianaResend]

I found this solution for the actuator attachment:

So I asked for the quote for the electric actuator and I saw that the actuator on the "Unimotion" is expensive (996.84€), so I'll try to find out the price of the actuators on the "FESTO" website.

Now I'm waiting for FESTO's response to the profile update request to get the prices.

:exclamation: :exclamation: :exclamation: Although I used the MTJ40 ECO L in the CAD, I believe it would be preferable to use the MTV40 1205, even though an additional piece is required to redirect the linear actuator's shaft.
