To determine the speed of rotation of the lead screw, we need to consider the relationship between the pitch of the lead screw and the pitch of the thread being cut.
Relationship between pitch of lead screw and thread:
The pitch of the lead screw is the distance the lead screw moves axially for one complete revolution. In this case, the pitch of the lead screw is given as 1.5 mm.
The pitch of the thread being cut is the distance between adjacent threads. In this case, the pitch of the thread is given as 0.8 mm.
Calculating the speed of rotation of the lead screw:
The speed of rotation of the lead screw can be calculated using the following formula:
Speed of rotation of lead screw = (Pitch of thread / Pitch of lead screw) * Speed of spindle
Substituting the given values:
Speed of rotation of lead screw = (0.8 mm / 1.5 mm) * 1500 rpm
Simplifying the equation:
Speed of rotation of lead screw = (8/15) * 1500 rpm
Speed of rotation of lead screw = 800 rpm
Therefore, the speed of rotation of the lead screw is 800 rpm.
Explanation:
The pitch of the lead screw and the pitch of the thread being cut determine the speed at which the lead screw needs to rotate to achieve the desired thread pitch. In this case, since the pitch of the thread being cut is smaller than the pitch of the lead screw, the lead screw needs to rotate at a higher speed to achieve the desired thread pitch.
By applying the formula for calculating the speed of rotation of the lead screw, we can determine that the lead screw needs to rotate at 800 rpm to cut a metric thread with a pitch of 0.8 mm on a lathe with a lead screw pitch of 1.5 mm.
Relationship between pitch of lead screw and thread:
The pitch of the lead screw is the distance the lead screw moves axially for one complete revolution. In this case, the pitch of the lead screw is given as 1.5 mm.
The pitch of the thread being cut is the distance between adjacent threads. In this case, the pitch of the thread is given as 0.8 mm.
Calculating the speed of rotation of the lead screw:
The speed of rotation of the lead screw can be calculated using the following formula:
Speed of rotation of lead screw = (Pitch of thread / Pitch of lead screw) * Speed of spindle
Substituting the given values:
Speed of rotation of lead screw = (0.8 mm / 1.5 mm) * 1500 rpm
Simplifying the equation:
Speed of rotation of lead screw = (8/15) * 1500 rpm
Speed of rotation of lead screw = 800 rpm
Therefore, the speed of rotation of the lead screw is 800 rpm.
Explanation:
The pitch of the lead screw and the pitch of the thread being cut determine the speed at which the lead screw needs to rotate to achieve the desired thread pitch. In this case, since the pitch of the thread being cut is smaller than the pitch of the lead screw, the lead screw needs to rotate at a higher speed to achieve the desired thread pitch.
By applying the formula for calculating the speed of rotation of the lead screw, we can determine that the lead screw needs to rotate at 800 rpm to cut a metric thread with a pitch of 0.8 mm on a lathe with a lead screw pitch of 1.5 mm.
