Estimation of Machining Accuracy by Measurement of Surface Texture Pattern

Ruled Surface Machining on Five-Axis CNC Machine Tools

To achieve high precision and high productivity in machining sculptured surfaces, a new architecture for a five-axis CNC interpolator for machining ruled surfaces was developed and demonstrated on a milling machine. The objective of the five-axis interpolator is to continuously maintain the milling cutter axis in parallel with the straight lines of the ruled surface. The cutter position and ori...

Optimal grids for five-axis machining

This paper presents a new grid generation method for tool path planning for five-axis machining based on minimization of the kinematics error. First, the procedure constructs a space-filling curve so that the scallops between the resulting tracks of the tool do not exceed a prescribed tolerance. At the second stage (which is the subject of this paper) a one-dimensional grid along the space-fill...

Minimization of the kinematics error for five-axis machining

Kinematics of a particular five-axis milling machine can drastically change the machining accuracy. Therefore, the reduction of the kinematics error is an important problem associated with the tool path planning. Our newoptimizationmethod employs a closed formof the kinematics error represented as a function of the positions of the cutter contact points. The closed form is derived from the inve...

A generic uniform scallop tool path generation method for five-axis machining of freeform surface

In this paper, a generic uniform scallop tool path generation method for five-axis machining is presented. Unlike the conventionalmethodswhich are based on the local surface geometry assumptions, thismethod is inspired by cutting simulation. Initially, the designed surface is planted with dense grasses. If a cutter is put onto the surface, the affected grasses will be cut short. All the affecte...
