The cutter runout is very common in machine milling and has a great effect on the surface accuracy. In this paper, a measurement of radial cutter runout in revolving milling tool is proposed by using the laser sensor. A laser beam is projected onto the milling tool edge and subsequently reflected. The diffuse reflection is captured by the sensor and the displacement between the cutter and the l...

CNC machining simulation has been developed to validate NC codes and optimize the machining process. Conventional simulation systems are usually performed in virtual environments, and this has the limitation that the operator needs to transfer the knowledge from the software environment to the real machining environment. The ARCNC system is proposed in this paper where the operator can observe ...

Abstract: Plain Milling is one of the progressive enhancements of miniaturized technologies which have wide range of application in industries and other related areas. Plain milling cutters are widely used in roughing and finishing of parts. The milling cutter geometry and distribution of inserts on the cutter body vary significantly in industry depending on the application. This paper presents...

In this paper, we present a geometric algorithm of finding the maximal cutter for 2-D milling operations. Our algorithm works not only for the common closed pocket problem, but also for the general 2-D milling problems with open edges. We define the general 2-D milling process in terms of a “target region” to be machined and an “obstruction region” that should not intersect with the cutter duri...

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...

Original scientific paper Aiming at answering the questions of wear and failure of hob in the rock breaking process, the rock breaking process was simulated in different broken rock conditions by using finite element method. The relationship between normal force, lateral force, rolling force and time was obtained by rock breaking simulation analysis on the single edge disc cutter. The rock stre...

Presented in this article is a new accurate tool swept volume generation algorithm based on a generalized cutter for five-axis NC simulation and verification. Based on the surface envelope theory and the differential geometry, using analytical method, the strict deduction process of critical curve equation and swept envelope equation for generalized cutter are given. The motion feature of the c...

Presented in this article is a procedure for representing the cutterswept surface (CSS) of a generalized cutter in a single-valued form, ; =,f(x, v). The key idea is that the z-value of the CSS at a 2D point (x, y) is expressed as the sum of 1) the z-value at a point on the silhouette curve of the cutter bottom surface and 2) the incremental z-value along the cutter movement direction. Thus, th...

OBJECTIVE This prospective study was conducted to compare the clinical outcomes of a 6-row 3-D linear cutter with the standard 4-row linear cutter in patients who underwent elective gastrointestinal surgery anastomosis. METHOD Patients who underwent elective open gastrointestinal surgery that included stapled anastomosis using a linear cutter (Proximate®, Ethicon Endo-Surgery, Cincinnati, OH)...
