左右切削法：如图一c所示，刀具采用与牙型槽等宽的尺寸，更多数控知识微信搜索公众号“数控编程教学”免费领取教程，加工中刀具纵向双向及横向做复合进刀。这种方式加工刀具受力情况与斜进法相似，较易加工出梯形螺纹。但该方式要求刀具纵向左右两侧移动结合横向进刀，对操作者技术要求较高，需多次操作后才能熟练掌握。
2、多刀组合法：一般梯形螺纹加工均采用这种方式。组合方式很多，如单刀加工中的三种只做为粗加工，留一定余量后再采用精加工刀具完成加工。再如图一d所示，这也是多刀组合中的一种，先用小切刀切直槽再用与牙型等宽的螺纹刀具加工。
二、螺纹编程指令
在GSK980T数控系统中，提供了三个加工螺纹的编程指令，分别是逐段加工螺纹指令G32、螺纹加工循环指令G92、复合循环指令G76。三个指令加工螺纹编程上有不同，进刀方式上也有不同，所造成的加工误差也不同。在编程中应仔细分析、合理选用，以加工出合格的工件。
1、逐段加工螺纹指令G32，格式如下：
G32 X(U) Z(W)F
使用本指令编程每次螺纹加工路径都至少需要4个程序段，如果螺纹加工使用斜线退出，每次走刀需要5个程序段。这种方法的缺点是程序过长、难以编辑、错误多并减小控制系统的存储能力。但这种方法也有一定的优点，程序员可以绝对控制螺纹的编程过程，这种控制中有了手的介入，从而可以螺纹加工中应用一些特殊的技巧，例如用比螺纹本身小得多的螺纹刀加工螺纹或使用圆头切槽刀加工大螺距螺纹。
2、螺纹加工循环指令G92，格式如下：
G92 X(U) Z(W)F
使用本指令主要优点是避免了重复数据，一条程序段，就能完成螺纹加工的定位、车削以及退刀，使程序更容易编辑，同时它还有螺纹收尾功能，不开退刀槽，也能实现车削螺纹的退刀。G32与G92一样均为直进式切削方法，在切削螺距较大的螺纹时，由于切削深度较大，刀刃磨损较快，从而是造成螺纹中径误差，但是其加工的牙形精度高，一般多用于小螺距螺纹加工。
