It is to point to the knife cutting tool to the knife the dot is adjusted dictate with the G92 in numerical control program (or the instruction that other builds workpiece coordinate to fasten) coincide of appoints coordinate position photograph, make in workpiece coordinate department namely the knife of cutting tool the dot is located in on dot removing a knife, fall in order to make in the control of numerical control program, from this the treatment appearance that cutting of cutting tool place gives is opposite at the spare parts do not machine the surface (fixed position is standard) true positional measure concerns, make sure the treatment precision of the spare parts asks thereby; In the meantime, to needing to use the process of many cutting tool in turning treatment process, the knife of new cutting tool after still should assuring to change a knife dot and primary cutting tool (standard cutting tool) knife dot photograph coincide (allow existence knife the error between spot position, but this error should be knowable, so that use cutting tool,compensation function or other method eliminate) . To realize pair of knives, in machining a process, use commonly try cut method, perhaps deploy pair of Dao Yi to undertake metrical will adjust cutting tool to the cutting blade of each cutting tool, but lathe of the economy that provides numerical control to device and other device are transformed and be become to using bed of general be open to traffic numerical control, or lathe of the test that faces numerical control education numerical control, it is difficult to configure and be being used of Dao Yi, for this kind numerical control lathe seeks a kind the handy and effective real significance with be had particular to knife method. The article offers a kind to be opposite simple and easily knife plan is shown 1 times like the graph, chart of plan of this pairs of knives showed the configuration that tries a club to knife standard, and each cutting tool and try a club to be opposite accordingly to knife standard the relation of knife action place, be opposite for test specimen namely character actually knife law. Tall to the point of a knife that assures each cutting tool answering to wait before the knife, the point of a knife of each cutting tool when making sure when cutting tool installation is on tool carrier passes line of main shaft center on the face that hold a knife. The method that uses this standard to try a club to undertake the knife is adjusted installing a knife to reach is opposite discusses below. The workpiece coordinate origin that sets process designing is in lathe origin O, the point removing a knife that process designing provides is: G92 X120.

0, by treatment the requirement needs to install cutting tool 1, 2, 3, 4, the installation of cutting tool and can undertake by undermentioned measure to the knife. Try a club to the knife 1.

Installation tries a club to install pair of knife standards to try a club on 3 ungual chuck to knife standard, zun Duan trying a club and car head end panel stick the clamp after tightening. 2.

Installation lathe tool 1 move means in order to nod to make tool carrier moves one proper place (assure cutting tool to there is what use quite to extend length) in X direction, cutting tool 1 outfit is on tool carrier, make sure action place photograph sticks its point of a knife and pair of knives that try a club to go up to knife standard close, when necessary can the hand turns main shaft is checked, affirm without by accident hind cutting tool clamp, finish cutting tool namely the installation of 1. 3.

Install cutting tool 2 installation cutting tool 2 before, make first cutting tool 1 with try a club to break away from a contact to knife standard, make tool carrier dislocation, for this, the order can execute below MDI means: G91 G00 X100.

0(tool carrier is regressive 50mm) , make next tool carrier dislocation; Again MDI: G91 G00 Z30.

0(tool carrier moves right 30mm) , finally again MDI: G91 G00 X-100.

0(tool carrier enters 50mm) , right now although tool carrier arrived at cutting tool the position holding a knife of 2, installation cutting tool 2 affirm point of a knife and stick to knife action place after tightening, cutting tool 2 clamp are worn at the knife on. Install cutting tool 3, 4 4.

With cutting tool the installation process of 2, cutting tool 3, 4 outfit go up at tool carrier. When cutting tool the knife of each cutting tool after 4 installation finish the distance of dot and O of workpiece coordinate origin is: X=47.

0mm(diameter dimension) , Z=170.

0mm. 5.

Because the program asks to be,adjust cutting tool dot removing a knife: G92 X120.

0Z350.

0, reason moves below MDI means: G91 G00 X73.

0, again MDI: G91 G00 Z180.

0, on the dot removing a knife that makes cutting tool arrives at program place to set, announce an end namely to the knife. Visible, this plan pair of can fast, knives that realize many cutting tool conveniently, when be like treatment process designing, the workpiece coordinate origin of make choice of is not nodded in O, after when can be being installed according to workpiece, locating the dimension A of standard position and machine tool, B undertakes conversion, the actual space size of origin of opposite workpiece coordinate when begging a cutting tool to end in outfit knife, adjust cutting tool dot removing a knife to go up again can. Because article meaning is offerring a kind of train of thought to the knife to be drawn lessons from for the person of the same trade, concern pair of knife standards to try a club consequently the fine structure of place of action of each pairs of knives was not shown piece, in the meantime, requirement of the precision that tries a club about this, material and production process are absent this give uncecessary details, should try a club to be used at education in lab of center of technology of my courtyard numerical control, the proof is feasible, to the student understanding concerns the concept of numerical control machine tool, the rate that raises operation of numerical control lathe is beneficial. Practical Shi Kegen occupies pair of specific knives to ask, adjust the structure that tries a club to the knife and dimension to apply neatly by oneself, be in to the installation of grooving cutting tool for instance cutting tool 1, 2, the position holding a knife of 4 all can undertake; Additional, if trying good right end to machine awl hole, what can be used at broach is general ask to the knife.
