Description
技术领域technical field

背景技术Background technique
目前，采用金刚石尖劈刀(刀尖为三棱锥形)进行衍射光栅机械刻划之前，需要首先通过可调刀架对金刚石刀具的安装角度(方位角、俯仰角、横滚角)进行调整，以满足刻划光栅槽形的几何形状要求。At present, before using a diamond beveling knife (the tip of which is a triangular pyramid) to mechanically scribe the diffraction grating, it is necessary to first adjust the installation angle (azimuth angle, pitch angle, roll angle) of the diamond tool through an adjustable tool holder. To meet the geometrical requirements of the groove shape of the grating.
但受制于现有的弹性配重式刀架工艺，安装角度参数很难做到准确量化调整或监控，导致调整后的安装角度具体参数和目标值产生一定的偏差，而且初始基准也很难确定。这对于追求高精度的光栅机械刻划工艺来说显然是不够的。However, due to the existing elastic counterweight tool holder technology, it is difficult to accurately quantify or monitor the installation angle parameters, resulting in a certain deviation between the adjusted installation angle specific parameters and the target value, and it is also difficult to determine the initial benchmark . This is obviously not enough for the pursuit of high-precision grating mechanical scribing process.
现有的方法是采用试错的方法反复检测光栅毛坯上的试刻槽形，并与目标槽形进行对比来确定安装角度参数的最终选取是否正确。但即使所刻槽形正确，也很难得知所对应的安装角度参数是多少，而且这样操作既浪费大量时间和成本，也显得很不科学。The existing method is to use trial and error to repeatedly detect the groove shape of the trial engraving on the grating blank, and compare it with the target groove shape to determine whether the final selection of the installation angle parameter is correct. But even if the engraved groove shape is correct, it is difficult to know the corresponding installation angle parameter, and this operation will waste a lot of time and cost, and it is very unscientific.

The straight line marking the main edge is the X axis, the coordinate origin O is at the tip of the knife, and the reference direction of the directional angle of the beveling knife is the Y axis. Through the spiral The right hand rule determines the Z axis;
S2、金刚石尖劈刀刀尖处的三条刃通过直线向量的形式给出，并表示为刀刃的单位向量矩阵[A]；S2. The three blades at the tip of the diamond beveling knife are given in the form of straight line vectors, and expressed as the unit vector matrix [A] of the blade;
S3、建立刻划坐标系X’Y’Z’-O，坐标系原点依然为刀尖点；X’Y’-O所确定的平面即为刻划的工作表面(光栅毛坯表面)；将刻划坐标系X’Y’Z’-O看成是刀具坐标系XYZ-O通过调节尖劈刀安装角度矩阵[B]，通过坐标转换获得的；S3, set up the marking coordinate system X'Y'Z'-O, the origin of the coordinate system is still the tool point; the plane determined by X'Y'-O is the working surface (grating blank surface) of marking; The coordinate system X'Y'Z'-O is regarded as the tool coordinate system XYZ-O obtained through coordinate conversion by adjusting the angle matrix [B] of the sharp knife installation;
S4、主刃在X’Y’-O平面内的投影与X’轴的夹角为尖劈刀调整后的方位角；主刃在X’Z’-O平面的投影与X’轴的夹角为俯仰角，XZ-O平面与X’Z’-O平面之间的夹角为横滚角。S4. The angle between the projection of the main edge on the X'Y'-O plane and the X' axis is the adjusted azimuth angle of the sharp knife; the angle between the projection of the main edge on the X'Z'-O plane and the X' axis The angle is the pitch angle, and the included angle between the XZ-O plane and the X'Z'-O plane is the roll angle.
S5、在刻划坐标系X’Y’Z’-O内，经投影变换矩阵[C]，将金刚石尖劈刀刀尖的三条刃向X’Y’-O平面投影，所得刀刃投影线单位长度分别向X’轴和Y’轴投影，得到投影后的刀刃投影向量矩阵[D]，上述矩阵[A]、矩阵[B]、矩阵[C]、矩阵[D]存在下述关系：[A][B][C]＝[D]；S5. In the marking coordinate system X'Y'Z'-O, project the three blades of the tip of the diamond chopper to the X'Y'-O plane through the projection transformation matrix [C], and the obtained blade projection line unit The lengths are respectively projected to the X' axis and the Y' axis to obtain the projected blade projection vector matrix [D]. The above matrix [A], matrix [B], matrix [C], and matrix [D] have the following relationship: [ A][B][C]=[D];

The blade projection vector matrix [D] can be obtained by measuring the vertical two-dimensional detection image after the blade tip indents the grating blank, such as a measurable optical microscope or scanning electron microscope, etc. The schematic diagram is shown in Figure 2. Through two stampings (the stamping distance along the marking direction is L), the relationship between the stamping edge and the marking direction or the marking coordinate system can be obtained, and it is convenient to find out the inside of the marking plane X'Z'-O The projection vector of . After the installation angle of the knife tip is adjusted, the projection relationship of the known unit vector matrix [A] of the blade to the marking plane is also certain, and the corresponding projection transformation matrix [C] is also a matrix containing the installation angle parameters. Therefore, if the transition matrix [E]=[B][C] is set, then: [E]=[A]-1[D].
求解上述矩阵即可获得作为过渡矩阵[E]中未知量的刀尖安装角度参数。与现有技术相比，本发明具有的优点和积极效果是：By solving the above matrix, the tool nose installation angle parameter can be obtained as an unknown quantity in the transition matrix [E]. Compared with prior art, the advantages and positive effects that the present invention has are:
