Filling method of pair of knives of lathe of economy numerical control and tone knife

01mm, equivalent of X coordinate pulse 0.

005mm, canal of 3 LED number shows, bigger the process of machine program editor below the clew information that canal of a number uses at showing condition of wave band switch falls and editor condition and the block order that issue automatically with airborne travel condition show, two lesser computation that show coordinate of motion of X, Z respectively are worth, coordinate of X, Z shows all be an unit with pulse equivalent. If the graph is shown 1 times, try with a knife cut A area, show tube of two decimal codes with *0 to clear, + Z to retreat a knife, the numerical value that Z coordinate indicates is S1, move moving function to try with the hand cut B area, + Z to time 0, reoccupy *0 to clear, + X to retreat a knife, the numerical value that X coordinate indicates notices for L1(at this moment point of a knife is L1/2) relative to B face distance, at this moment the C dot of cutting tool fall back on, with *0 to clear, c dot is cutting tool initial drop. Attached drawing is measured try cut paragraph of workpiece diameter to be D0, the requirement machines a diameter to be D, treatment length is F, use program of feed of radial of cutting tool of opposite process designing to be: U-(L1+2(d0/2-d/2)) namely U-(L1+d0-d) , instruction of treatment length F is W-(S1+f) . After the tone knife of lathe of 3 economy numerical control fills and changing knife C to nod to clear, change 2 knives, move a function to try with the hand cut A area, the value that all indication all replaces above of Z coordinate indication S2(numeric, similarly hereinafter) , try cut coordinate of B face X to show L2, criterion 2 knives fill relative to the knife of a knife (often say the first group of knives fill) for: Two coordinate of U(L1+L2)W(S1+S2)T01 X, Z are answered 0, change 3 knives, move a function to try with the hand cut A area, z coordinate shows S3, try cut coordinate of B face X to show L3, criterion 3 knives fill relative to the knife of a knife for: Cutting tool of U(L1+L3)W(S1+S3)T02 the others debugs methodological ibid analogize relative to what knife of a knife fills. If 2 knives are changed in treatment, use T21 statement, after changing a knife to walk along the first group of knives to fill, 2 knives point of a knife runs cutting tool dot of initial drop C; Change 3 knives to use T32 statement, after changing a knife to walk along the 2nd group of knives to fill, 3 knives point of a knife runs cutting tool dot of initial drop C, the treatment that change a knife ends, change the first knife with T10, cancel a knife to fill, point of a knife of the first knife runs C point, undertake issueing 10 treatment. The attention when 4 pairs of knives move a knife to fill eliminates guide screw of ball of guide screw backlash to have backlash, in moving knife filling process to the knife the X with cutting tool bit more initiative fall back on, Z cancels knife strike, the statement such as G26, G27, G29 is used when wanting to end with treatment return the trend with bit more initial cutting tool to agree, return photograph clearance error in order to eliminate. If attached drawing place is shown, try with a knife cut A area, after two coordinate show to clear + Z to retreat a knife 1.

00mm, if exceeded 1.

00mm, like 1.

08mm, should - Z is moved to the hand to be less than 1.

00mm, the numerical value that be less than should be more than the value of guide screw backlash, eliminate the goal of backlash in order to achieve, again + Z is moved to the hand to 1.

00mm;+X to retreat a knife also such, the direction retreating a knife after be being cut to when knife and tone knife fill, trying wants to secure, backlash is eliminated with the program when process designing [2] . Treatment is over 1999.

10 finish, retreat a knife with G26, also noticing is + Z, + X to retreat a knife to come cutting tool is bit more initiative C. Filling value of knife of the change after 5 cutting tool wear away and each tool concern fill by afore-mentioned tone knives method, want to ask with precision of dimension of the circle outside the car tall cutting tool is a knife, other vehicle end panel, grooving, pour the dimension precision such as horn to ask low cutting tool is 2, 3, 4 knives, the diameter is measured in machining a process so (if a knife has,wear away, the diameter greatens) increase machine program first paragraphs - the value that X estimates to feed, contented diameter machines precision. Although other cutting tool has wear away, but want measure only not out of tolerance, do not need to move a knife to fill to the knife again; When machining dimension out of tolerance, can revise a knife to fill to the knife afresh, also can be worth according to out of tolerance, the knife that revises corresponding cutting tool fills, such tone knives fill can avoid to produce an effect to other cutting tool.
