Tool deflection compensation in peripheral milling of curved geometries

Compensation of tool deflection in micromilling using workpiece holder control device

“…(3) can be simplified using a Taylor series: (5) From Eqs. (4) and (5) the shortened tool length is given by (6) From Eq.…”

“…3,4 A variety of studies have been presented to overcome this problem. Rao et al 5 estimated the cutting force based on a cutting model and modified the tool path by considering machining errors calculated by the predicted cutting force and a tool deflection model. Saffer et al 6 estimated tool deflection and machining errors using the finite element method (FEM).…”

Fabrication of small aspheric moulds using single point inclined axis grinding

“…Kim et al developed a new sub-micron control algorithm in order to interpolate tool path in grinding and polishing aspheric surfaces [10]. To improve the profile accuracy through reducing the effects of tool fabrication and positioning errors and tool wear, several techniques for precise truing and dressing grinding wheels were developed [11][12][13][14], in-process measuring methods for form errors was employed [5,15] and a number of compensation approaches for tooling errors [16][17][18], tool wear [19][20][21], machine tool geometric error [22,23] and thermal effect [24,25] were proposed.…”

“…For instance, the quality of truing and dressing of grinding wheels and tool wear had such significant effect on the profile accuracy of the ground surface [16][17][18][19], so that the compensation algorithm for such errors must be more efficient and rigorous. It was…”

An intelligent self-learning method for dimensional error pre-compensation in CNC grinding

“…A strategy of error compensation for workpiece dimension is presented based on the AI approach named synergistic interactions among modeling, sensing, and learning. There are also some interesting publications in the area of cutting force induce error [11,12] and thermal error [13] compensation.…”
