5-axis iso-scallop tool paths along parallel planes
نویسندگان
چکیده
This paper presents a new method of computing constant scallop height tool paths in 5-axis milling. Indeed, usual iso-scallop tool path computation methods in 3-axis or 5-axis milling generate tool path self-intersections, which prevent from reaching the required quality and productivity. The proposed approach consists in following parallel planes in 5-axis milling to avoid self-intersection of the tool path. The constant scallop height is guaranteed by modifying the machined strip width by means of the orientation angles of tool axis (yaw and tilt angles). Resulting scallop height and surface roughness are simulated using the N-Buffer method.

Iso-scallop tool path generation in 5-axis milling
This paper presents a new method of computing constant scallop height tool paths in 5-axis milling on sculptured surfaces. Usually, iso-scallop tool paths computation methods are based on approximations. The attempted scallop height is modelled in a given plane to ensure a fast computation of the tool path. We propose a different approach, based on the concept of the machining surface, which en...
متن کاملFive-axis Strip Machining with Barrel Cutter Based On Tolerance Constraint for Sculptured Surfaces
Taking the design tolerance into account, this paper presents a novel efficient approach to generate iso-scallop tool path for five-axis strip machining with a barrel cutter. The cutter location is first determined on the scallop surface instead of the design surface, and then the cutter is adjusted to locate the optimal tool position based on the differential rotation of the tool axis and sati...
متن کاملOptimal contour orientations for machining of free{form surfaces
In contour machining of free{form surfaces with a ball{end cutter, the tool contacts the surface along loci that correspond to sections by a set of parallel planes, with equidistant spacing and common normal N. For a given tool radius, the greatest scallop height between successive tool paths is suppressed by choosing an orientation for the contouring planes that will maximize, over the entire ...
متن کاملIso-level tool path planning for free-form surfaces
The aim of tool path planning is to maximize the efficiency against some given precision criteria. In practice, scallop height should be kept constant to avoid unnecessary cutting, while the tool path should be smooth enough to maintain a high feed rate. However, iso-scallop and smoothness often conflict with each other. Existing methods smooth iso-scallop paths one-by-one, which make the final...
متن کاملA 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...
