| Knife the choice of with slice to pare dosage of a |
Knife of choice with slice to pare dosage really settle is number control to
process a craft in of importance contents, it not only influence number control
process of tool machine an efficiency, and direct influence process quality.
CAD/CAM technique of development, make direct in the number control
process make use of CAD of design the data make possible, especially tiny
machine and number control tool machine of allied connect, make design,
craft programming and plait distance of the whole process all in calculation
on board completion, general don’t need to be output specialized of craft
document.
Now, the many CAD/CAM software package all provide auto plait distance
function, these software general is in the plait the distance interface hint
craft programming of relevant problem, for example, knife choice, process
path programming and slice to pare dosage enactment etc., plait distance
personnel want ～only constitution relevant of parameter, can auto born
NC procedure combine deliver to number control tool machine completion
to process.Therefore, number control to process medium of knife choice
with slice to pare dosage assurance is in person’s machine to hand over
appearance with each other bottom completion, this with common the tool
machine process formation fresh and clear of contrast, also in the meantime
request plait distance the personnel have to control knife choice with slice
a basic principle that pare dosage’s assurance, at plait distance full
consideration number control process of characteristics.This text logarithms
control a plait a distance in the knife that have to face choice with sliced to
pare dosage assurance problem to carry on study, give some principle and
suggestion, and rightness should attention of the problem carried on
discussion.
A, number control a category and characteristics of process the in common
use knife
Number control to process knife have to orientation number control tool
machine high speed, efficiently with automation degree Gao of
characteristics, general should include in general use knife, in general use
connect haft with a little amount appropriation haft.The haft want to be
allied to connect knife and pack a head at the tool machine motive up,
so already gradual standardize with the series turn.Number control a knife
of the classification have variety method.Can is divided into according to
the knife structure:The ① whole type;The ② inset type, the adoption weld
or the machine clip type conjunction, the machine clip type again can is
divided into not to turn with can turn 2 kinds;The ③ special pattern, such
as compound type knife, reduce earthquake type knife etc..Can is divided
into according to manufacturing the material use by knife:The ① high
speed steel knife;The ② hard quality metal alloy knife;The ③ diamond
knife;④ Other material knife, such as sign square Boron Nitride knife,
porcelain and ceramics knife etc..From slice to pare a craft top can is
divided into:The ① car pare knife, circle outside the cent, inside bore,
thread, incise knife etc. variety;The ② drill to pare a knife and include
auger, Jiao knife, silk awl...etc.;The ③ Tang pare a knife;The ④ Xian pare
a knife etc..For the sake of orientation number control tool machine to the
knife enduring, stability, easy adjust and can change the request, the
last few years of etc., the machine clip type can turn a knife to get
extensive of application, attain the whole piece to control knife on the
amount of 30% ～ be 40%, metals cut off the quantity share total
amount of 80% ～ be 90%.
Number control a knife and common tool machine top the knife for
use compare, have many dissimilarity of request, main have the following
characteristics:
The ⑴ is rigid good(BE particularly thick to process a knife), accuracy
Gao, the anti- flap and hot transform small;
⑵ Compatibility good, easy to fast change the knife;
⑶ Life span Gao, slice to pare function stability, credibility;
⑷ Knife the size of be easy to adjust, with decrease change the knife
adjustment time;
⑸ Knife should ability credibility break scraps or book scraps, for the
convenience of in slice scraps of expel;
The ⑹ series turn, standardize, for the convenience of at the plait
distance and knife management.
Two, number control to process a knife of choice
The choice of knife is at number control plait distance of person’s
machine hand over with each other appearance bottom to carry on.
Should process ability, work piece the function of the material, process
a work preface and slice to pare dosage and other a related factor
according to the tool machine exactitude choose to use knife and haft.
Knife choice total of principle BE:Install to adjust convenience, rigid
good, enduring degree and accuracy Gao.Under the premise satisfied
to process request, as far as possible the choice shorter haft, with
exaltation knife process of rigid.
Selection knife, make knife of size and is processed a work piece of
the surface size went with should.Produce medium, the periphery
process of outline of the flat surface spare parts, often adoption sign
Xian knife;Should choose hard quality metal alloy razor blade Xian knife
when the Xian suppress noodles;Choose a high speed steel to sign Xian
knife while processing a convex set, cave slot;Process semi-finished
product surface or thick process bore, can the selection inset hard quality
metal alloy the corn Xian of the razor blade knife;Rightness some
stereoscopic type noodles with change the process of shape of the
oblique angle outline, often adoption ball head Xian knife, wreath form
Xian knife, the taper Xian knife and the dish form Xian knife.
At carry on freedom the curved face process, slice to pare speed to zero
because of the carry of ball head knife department, therefore, for assurance
process accuracy, slice to pare line to be apart from general obtain very
ability airtight, past ball head the Jing iner common use than curved face
process.But crew cut knife process quality and slice to pare an efficiency an
all better than ball head knife in the surface, therefore, as long as at
assurance however slice of under the premise regardless is a curved face
of thick process still the Jing process, all should prior choice crew cut knife.
Moreover, enduring degree and accuracy and knife of the knife price relation
biggest, have to attractor BE, at majority under the circumstance, choice
good knife although increment knife cost, bring from here of process quality
and process an efficiency of exaltation, then can make whole process cost to
consumedly lower.
In processing center, various knife pack on the knife database respectively
and press the procedure provision to be at any time carry on choosing knife
and change the knife action.Therefore have to adoption standard haft, in order
to make to drill, Tang, expand, the Xian pare etc. the work make appointment
to post of standard knife, quick, accurately pack the tool machine principal axis
or the knife database up.Plait distance personnel should understanding the
haft use on tool machine of structure size, adjust method and adjust scope,
in order to at plait distance assurance knife of path to with the stalk is to the
size.The our country process the center adoption TSG tool system currently,
its haft have already kept handle(three kinds of specification) and awl handle
(four kinds of specification)2 kinds, total include 16 kinds of dissimilarity the
haft of the use.
In the economy the number control process, because of knife of the blade
whet, measure with replace much behavior the work hand move to carry on
and take up assistance time longer, therefore have to be reasonable
arrangement knife of row row order.General should follow the following
principle:① As far as possible decrease knife amount;② A knife after packing
to clip, should completion it ability carry on of havings process part;③ Thick
Jing process of knife should separate usage, even is homology the knife of
the size specification;④ First the empress of the Xian drill;The ⑤ carry on
curved face Jing first to process and two dimensions in the juniors line
outline Jing process;⑥ Under the circumstance that possibility should make
use of number to control tool machine possibly of auto change the knife
function, with exaltation produce efficiency etc..
Three, the number control to process to slice to pare dosage of assurance
Reasonable choice slice a principle of pare the dosage BE, thick process,
general with exaltation rate of production is lord, but also should consideration
economy with process cost;When half Jing processed to process with Jing,
should at assurance process under the premise of quality, give attention to
both to slice to pare an efficiency, economy and process cost.Concrete number
should according to the tool machine manual, slice to pare a dosage manual,
and combine experience but settle.
The ⑴ slice to pare depth t.In the tool machine, work piece and the knife
just degree under the circumstance for allow, t equal to process remaining
quantity, this is exaltation rate of production of a valid measure.For the sake
of assurance accuracy and surface of the process of spare parts rough degree,
general should stay certain of the amount of remaining carry on Jing to process.
Number control the Jing of tool machine to process amount of remaining slightly
small at the common tool machine.
