梯形螺紋加工是車削加工中一項基本技術，但由于數控車床的加工方式，特別是經濟型數控車床在加工梯形螺紋中的局限較多，因此，梯形螺紋的編程及加工都成為了難加工技術。本文中主要研究了在GSK980T數控系統中如何進行梯形螺紋編程、加工及精度控制。
一、梯形螺紋的切削方法
車削加工梯形螺紋的切削方法有很多，一般有單刀完成和多刀完成兩種。
1、單刀完成：這種方法對于螺距小于4mm的梯形螺紋可行，當螺距大于4mm后由于切削力和刀具磨損的影響，單刀完成則效果不好。具體方法有以下幾種：
直進法：如圖一a所示，刀具采用與牙型槽等寬的尺寸，加工時只做橫向進刀。這種方法在加工加工梯形螺紋時，螺紋的牙型精度較高，但由于三刀刃均參與切削，切削力過大容易導致加工變形，只在小螺距螺紋加工時采用。
斜進法：如圖一b所示，刀具采用與牙型槽等寬的尺寸，加工中刀具縱向和橫向做復合進刀。這種方法在加工中刀具只有兩面刀刃受力，可適當減小切削力，
但由于兩刃切削，刀具的磨損程度不同，加工中易出現刀尖角發生變化，而造成牙型精度較差。這種方式只在梯形螺紋粗加工或螺紋精度不高時采用。
