Feed Rate: The speed at which the cutting tool moves across the work piece. It is usually measured in inches per minute (IPM). Tool Offset: This is the distance from the cutting tool to the center of the work piece. It is used to set the cutting depth of the tool. Spindle speed: This is the speed at which the spindle of the machine rotates. It is measured in revolutions per minute (RPM).
Tool Path: This is the path that the cutting tool follows as it moves across the work piece. It is programmed into the CNC machine before the machining process begins. Cutting Depth: This is the depth of the cut that the tool will make. It is usually measured in thousandths of an inch (thou). Axis of Movement: This is the direction in which the machine moves its cutting tool. It can be programmed to move in three different directions: X, Y, and Z. Tolerance: This is the allowable deviation in size or shape from the desired part design. It is typically measured in thousandths of an inch (thou). Rapid Move: This is the fastest speed at which the machine can move its cutting tool. It is usually measured in inches per minute (IPM). Lead In/Lead Out: This is the way the cutting tool is programmed to enter and exit the cut. It is used to ensure a smooth transition between cuts.
