Lathe PCR is a free Android application developed by SHIN yong weon. It falls under the category of Business & Productivity. This program is specifically designed for chamfering and rounding. With Lathe PCR, users can input values such as x, z, chamfering value, radius of the circle or the radius of the arc tangent, and noseR. Based on these inputs, the program can calculate various coordinates.

These coordinates include two coordinates for chamfering, two coordinates for processing arc, four coordinates tangent, and compensated coordinates. Users also have the option to choose the outer diameter and inner diameter. It is important to note that the program is fixed at a 45-degree angle. Lathe PCR provides a convenient and efficient solution for individuals working with chamfering and rounding operations.
