1.Nyob rau hauv NC programming, qhov ntev thiab txoj hauj lwm ntawm tag nrho cov ntsiab lus, kab thiab nto yog raws li lub hauv paus chiv keeb ntawm programming. Yog li ntawd, nws yog qhov zoo tshaj plaws los muab qhov sib koom ua ke qhov ntev ncaj qha rau ntawm qhov kos duab, lossis sim hais qhov ntev nrog tib datum.
2. Cov xwm txheej ntawm cov ntsiab lus geometric yuav tsum ua kom tiav thiab raug
Hauv kev ua haujlwm, programmers yuav tsum nkag siab tag nrho cov geometric cov ntsiab lus tsis ua haujlwm uas tsim cov qauv qhia thiab kev sib raug zoo ntawm cov ntsiab lus geometric. Vim hais tias tag nrho cov ntsiab lus geometric ntawm qhov contour yuav tsum tau txhais thaum lub sijhawm ua haujlwm tsis siv neeg, thiab cov kev sib koom ua ke ntawm txhua qhov yuav tsum tau suav thaum lub sijhawm ua haujlwm, txawm tias qhov twg tsis meej lossis tsis meej, programming tsis tuaj yeem ua. Txawm li cas los xij, vim tsis muaj kev txiav txim siab lossis tsis saib xyuas los ntawm cov neeg tsim qauv hauv cov txheej txheem tsim, cov kev ntsuas feem ntau tsis tiav lossis tsis meej, xws li seb lub arc thiab txoj kab ncaj nraim, lub arc thiab arc yog tangent, sib tshuam los yog sib cais. Yog li ntawd, thaum tshuaj xyuas thiab tshuaj xyuas cov duab kos, koj yuav tsum ceev faj thiab tiv tauj tus tsim qauv hauv lub sijhawm yog tias koj pom muaj teeb meem.
3. Txhim khu kev qha qhov chaw siv
Nyob rau hauv CNC machining, cov txheej txheem machining feem ntau yog concentrated, thiab nws yog ib qho tseem ceeb heev kom nrhiav tau nrog tib datum. Yog li ntawd, nws yog ib qho tsim nyog los teeb tsa qee qhov kev pabcuam cov ntaub ntawv, lossis ntxiv qee cov txheej txheem tus thawj coj rau qhov khoob.
4. Uniform geometry hom lossis loj
The shape and inner cavity of the part should preferably adopt a unified geometric type or size, which can reduce the number of tool changes, and may also apply control programs or special programs to shorten the program length. The shape of the part is as symmetrical as possible to facilitate programming with the mirror machining function of the CNC machine to save programming time.
