Headline: ? Fear of cutting of the feet of poisonous glucoside of Nai of δ of ス of hook of fear of poisonous glucoside cutting of the feet hooks ブ Ga?G40, g41, compensation of radius of G42 cutting tool dictates the form is as follows: G17 G41(or G42) G00(or G01) X Y D or G18 G41(or G42) G00(or G01) X Z D or G19 G41(or G42) G00(or G01) Y Z D. G41 of direction of compensation of 1 cutting tool is opposite advance at cutting tool side of square towards the left undertakes compensating, call Zun Dao to fill. G42 is undertake compensating on the right side of ongoing to cutting tool direction, call right knife to fill. From cutting tool life, treatment cutting tool radius compensates radius of functional cutting tool to compensate instruction G40, g41, compensation of radius of G42 cutting tool dictates the form is as follows: G17 G41(or G42) G00(or G01) X Y D or G18 G41(or G42) G00(or G01) X Z D or G19 G41(or G42) G00(or G01) Y Z D; G40(a) 　 (B) pursues 6.

G41 of direction of compensation of 1 cutting tool is opposite advance at cutting tool side of square towards the left undertakes compensating, call Zun Dao to fill. If pursue 6.

1a place is shown. Be equivalent to arranging mill at this moment. G42 is undertake compensating on the right side of ongoing to cutting tool direction, call right knife to fill. If pursue 6.

2b place is shown. Be equivalent to going against mill at this moment. From surface roughness of precision of cutting tool life, treatment, surface character, suitable mill effect is better, accordingly G41 is used more. D is address of knife filling date, it is the memory address that cutting tool radius records in the system, the numerical value that follows from the back is cutting tool date, with numerical value of compensatory of radius of the cutting tool in call memory. Address of knife filling date can have D01-D99 in all 100 addresses. Among them value can input corresponding in watch of memory cutting tool cutting tool date beforehand with MDI means locally. When undertaking cutting tool is compensated, want to choose knife filling plane with G17/G18/G19, default condition is XY plane. G40 is to cancel cutting tool radius to compensate a function, instruction of compensatory of cutting tool radius cancels to all be G40 on all plane. G40, g41, g42 is mode code, they can be cancelled each other. Use cutting tool compensates functional advantage to depend on: · need not consider the radius of cutting tool when process designing, undertake process designing to dimension by design place directly, the radius that cutting tool inputs when wanting to be being machined actually only is worth can. · can make the program of rough machining simplifies. Use compensation of conscious radius of change cutting tool, usable and same cutting tool, same process, different cutting surplus completes treatment. Union pursues below 6.

Because enter cutting tool state,its reason is hind, can numerate only two successive paragraphs, these two paragraphs do not have feed, also do not make give vector, cannot determine ongoing direction.
