Abstract
Description
−Gwは、機械加工によって影響される工作物のゾーンの最初の幾何モデルである。
−Gtは、工具のアクティブ部分の幾何モデルである。Gtは、一定になり得るが、たとえば工具の摩耗を考慮するためにこのモデルにおけるゆっくりとした変動を予測し、説明することを可能にする。より具体的には、この幾何モデルは、実際、さまざまな個々の工具(歯、インサート、刃、・・・)を説明する一連のモデルである。幾何モデルは、表面モデルである。これは、工具のアクティブ部分、特にその切削面を表す。
Fω(t)は、周期
q(t)は、一連のパラメータqi(t)の列行列である、
Qc(t)は、工具と工作物の間の相互作用から生じる一般力を表している。この一般力は、切削モデルを用いて得られた局所力Fcut(t)から導出される、
Qb(t)は、Qc以外の一般力を表している。これは、特にクランプ力に関する、
M(t,Ω)は、質量行列である、
C(t,Ω)は、減衰行列である、
K(t,Ω)は、剛性行列である。
