Compensation of radius of point of a knife dictates dictates: of of G40 of of of G00 of of of G42 X(U)_Z(w)_; of of of G01 of G41 notices (1) .
G41, g42, g40 instruction cannot be written inside same block with instruction of circular arc cutting. (2) .
Before calling new cutting tool or when changing cutting tool to amend way, a cutting tool is compensated. of of string 6 (3) .
G40 block is added at the back of G41 or G42 block, can cancel compensation of radius of point of a knife. 2.

Cutting of I only then dot and the radius with taper seat terminal cutting are poor. 2.
The end panel cutting that takes taper dictates dictates circularly: Cutting of end panel of K of G94X(U)_Z(W)_K_F_; only then the dot is in to terminal displacement the coordinate of Z direction is worth increment size. 3.
Simple circular arc processes instruction: of G03 R_ of of of X(U)_Z(W)_ F_; of of G02 I_K_ 1.
Deep space processes instruction: R of of of G74Z(W)_Q_; of G74R_; processes the volume that retreat a knife every time, Z is gotten cut total depth, Q is gotten every time cut deepness, 1.
G75 dictates format dictates: The radial in process of grooving of R of of of G75X(U)_Z(W)_P_Q_R_F_; of G75R_; (the quantity retreating a knife of X) , X is the biggest the X axis that cuts dark spot is absolutely coordinate, Z is the biggest the Z axis that cuts dark spot is absolutely coordinate, the radial in process of grooving of P (the quantity retreating a knife of X) (radius is worth) , after radial of Q cuts a Dao Kuan, in the mobile quantity of Z, after cutting tool of R cuts groove, in bottom land edge - the quantity retreating a knife of Z direction. 2.
The using that the subprogram moves dictates: of M98P**** ****; for example: of of M98P42000; string 7 makes clear call a subprogram twice 2000. of M98P2; makes clear call 2 programs. 3.
Wait for pitch whorl cutting to dictate dictates: X of G32(U)_Z(W)_F_; , z is the absolutely coordinate of whorl terminus, for example: G32X29.

G76 dictates format dictates: Finish machining of M of of of G76X(U)_Z(W)_R_P_Q_F_; of G76GmraQ_R_; repeats a time, R pours horny amount, angle of point of a knife of whorl of A, Q is the smallest be measured by penetration of a cutting tool (radius is worth) , the unit is micron. Surplus of finish machining of R (radius is worth) , the unit is millimeter. Radius of whorl of R of of of G76X(U)_Z(W)_R_P_Q_F_; is worth (radius is worth) , tooth of whorl of P is deep (radius is worth) , the unit is micron. Deepness of cutting of first time of Q (radius is worth) , the unit is micron. Lead of whorl of F. The unit is millimeter. 7.
Change lead thread machining (G34) instruction: F of of G34 X(U)_Z(W)_F_K_; grows axial direction lead, the unit is main shaft of K of millimeter every turn the increment of lead or reduce an amount, the unit is millimeter every turn CNC Milling CNC Machining
