Understanding the Problem:
In a CNC machine feed drive system, a stepper motor is used to control the movement of the lead screw. The stepper motor has a step angle of 1.80, which means it takes 200 steps to complete one revolution (360 degrees). The lead screw has a pitch of 2 mm, indicating that for each complete revolution of the lead screw, it moves by a distance of 2 mm.
Calculating the Basic Length Unit (BLU):
To determine the basic length unit (BLU) for this drive, we need to find the smallest distance that can be accurately moved by the stepper motor. This can be calculated by dividing the lead screw pitch by the number of steps per revolution of the stepper motor.
Given data:
- Step angle of stepper motor = 1.80
- Pitch of lead screw = 2 mm
Step 1:
Calculate the number of steps required to move the lead screw by one pitch:
Number of steps = 360 degrees / Step angle = 360 / 1.80 = 200 steps
Step 2:
Calculate the distance moved by the lead screw for one step:
Distance moved per step = Pitch / Number of steps = 2 mm / 200 steps = 0.01 mm
Step 3:
Convert the distance moved per step to microns:
1 mm = 1000 microns, so 0.01 mm = 10 microns
Therefore, the basic length unit (BLU) for this drive is 10 microns. This means that the stepper motor can accurately move the lead screw by increments of 10 microns, allowing precise control over the positioning of the CNC machine.
