Calculation of Time Required for Ultrasonic Drilling
To calculate the time required for ultrasonic drilling, we need to consider the effective stress, amplitude of tool oscillation, frequency of the machine, and other relevant data.
Firstly, we convert the static stress to a more appropriate unit and determine the effective amplitude considering the efficiency of each pulse.
Then, we calculate the effective force by multiplying the stress with the area of the hole. After obtaining the volume of the hole, we can use the formula to find the time necessary for drilling.
Ultrasonic drilling offers a precise and efficient method for working with tough materials like tungsten carbide. By understanding the key factors influencing the drilling process, we can optimize operations and achieve accurate results.
Effective Stress and Amplitude Calculation
In ultrasonic drilling, the conversion of static stress to an appropriate unit, such as kg/mm², ensures a more accurate representation of the force applied during the process. The effective amplitude of tool oscillation is crucial for determining the actual impact on the material.
