10分）1、圆周铣顺铣具有能压紧工件，使铣削平稳，铣刀后面的挤压及摩擦小等优点，所以刀具磨损慢，工件加工表面质量好，一般都采用顺铣。（）2、采用弯颈刨刀刨削时不易“扎刀”。（）3、中心架和跟刀架在车削细长轴类工件时用做辅助支承，以提高工件的装夹刚性，防止工件在加工中弯曲变形。（）4、切削力 Fc 是总切削力 F 在主运动方向上的正投影，与切削速度Vc 的方向一致。（）5、切削过程中，产生的切削热越多，则切削温度一定越高。（）6、氩弧焊时，因为电极不熔化，因此均需外加熔丝熔入熔池。（）7、铸铁、不锈钢等材料不能气割。（）8、为提高金属的塑形和降低锻造时的变形抗力，始锻温度越高越好。（）9、自由锻件产生裂纹缺陷的原因主要是坯料材质不好、加热不充分，终端温度过低和锻件冷却不当。（）10、铸型浇注后应尽快进行落砂，以缩短生产周期。（）四、名词解释题：（每小题5
