2、基準(zhǔn)和精基準(zhǔn)。根據(jù)選好的基準(zhǔn),制定工藝路線,通常制定兩種以上的工藝路線,通過工藝方案的比較和分析,再選擇可以使零件的幾何形狀、尺寸精度及位置精度等技術(shù)要求得到合理的保證的一種工序。第三步,根據(jù)已選定的工藝路線,確定每一步的切削用量和切削工時(shí),并選擇合適的機(jī)床和刀具。對于粗加工還要校核機(jī)床功率。最后,設(shè)計(jì)第三道工序——鉆法蘭盤孔的夾具。先提出設(shè)計(jì)問題,再選擇定位基準(zhǔn),然后開始切削力和夾緊力的計(jì)算和定位誤差的分析。然后把設(shè)計(jì)的過程整理為圖紙。通過以上的概述,整個(gè)設(shè)計(jì)基本完成。關(guān)鍵詞加工工藝;夾具設(shè)計(jì).資料AbstractAspecializedmai
