“…Such an approach could sustain simulation precision and shorten computing time. Moreover, Yun [5] also proposed a method to move the meshes crossing boundaries so as to make the locations of border meshes and real borders in line. A better precision could then be obtained without increasing the number of meshes.…”

Abstract-In this paper, a method integrating NC decoding and solid milling simulation to solve this problem is proposed. A modified Z-Map computational algorithm is adopted and it directly uses straight line and arc interpolation algorithms to calculate mesh position and Z coordinates of tool scanning surface according to tool path and initial tool scanning boundary in reducing the long computation time. The proposed method in this paper includes NC decoding, solid cutting simulation, virtual measuring, and the residual material calculation in previous process. This method owns the advantage of no need to solve non-linear equation any more. Subsequently, through comparing the product surface with the data decoded from the NC program, the magnitude and the position of the machining geometry error could be calculated to serve as important reference for the machining process of complex geometry such as a 3D surface. An example was demonstrated to the feasibility of the proposed method.

“…For the machining simulation integrated with cutting force estimation, Yun et al [5,9] predicted cutting force for the initial transient toolpath and the stable middle toolpath of flat-end milling tool based on Z-Map method. Fussel et al [10] also estimated cutting force on five-axis sculptured surface milling operation.…”

Chatter has been a problem in CNC machining process especially during pocket milling process using an end mill with low stiffness. Since an iterative time-domain chatter solution consumes a computing time along tool paths, a fast chatter prediction algorithm for pocket milling process is required by machine shop-floor for detecting chatter prior to real machining process. This paper proposes the systematic solution based on integration of a stability law in frequency domain with geometric information of material removal for a given set of tool paths. The change of immersion angle and spindle speed determines the variation of the stable cutting depth along cornering cut path. This proposed solution transforms the milling stability theory toward the practical methodology for the stability prediction over the NC pocket milling.

“…The calculation of chip load means a cutting force simulation that affects cutting tool deflection or prediction of tooth failure caused by abrupt changes of the cutting state. Recently, virtual machining has required more accurate and powerful functions to ensure tasks are performed accurately [4][5][6][7]. For this end, many researchers have been interested in the prediction of machined surface roughness [8][9][10][11] or cutting force [12][13][14].…”
