Calculations for Programming the Lathe 311

The class Calculations for Programming the Lathe provides an in-depth explanation of various calculations necessary to determine tool positions on the lathe or turning center. Trigonometry and circle geometry are used to calculate the toolpaths used in lathe cutting operations. This class introduces the foundational toolpaths and trigonometric equations, including tool nose radius compensation. It then provides a detailed explanation of the calculations needed to determine tool positions for drilling, chamfering, and turning partial and full arcs. An understanding of trigonometry and how it can be applied on the lathe is necessary to perform any lathe operation programming. A knowledge of TNRC, drilling, and arc calculations will allow students to program most basic CNC lathe operations.
