In a case of a linear positioning stage, the positioning accuracy is influenced by angular error (pitch, yaw, and roll), straightness (vertical and horizontal), and the lead error. Here is defined the positioning error is came from the lead error of screw as one of main reason and it is accumulated when the linear stage moves unidirectional within the full stroke. That s why it is called as Accumulated Lead Error (ALE). It is difference between a real output and ideal / calculated input. When the linear stage makes positioning in each position by each commanded values, there is an error between them. It is measured and calculated like following; (Actual displacement) (Commanded displacement value). The maximum deviation within the full stroke is defined as the ALE. 얼라인먼트스테이지X 진공스테이지Vacuum Stage Maximum error 최대차 레이저길이측정기 자동 X 스테이지 Motorized X stage 임의의한점 ( 기준으로하는측정점 ) 에서같은방향으로위치결정을하고그위치를측정합니다. 이측정점에대해서 7 회측정을하고그최대차이를구합니다. 이조작을소정의위치에서하고구한값의최대값의 1/2 에 ± 를붙인값을반복위치결정정도라고합니다. 단, 소정의위치란 X 스테이지는중앙 양끝의 3 점이며, 스위벨및 스테이지는중앙의 1 점으로합니다.

The angular repeatability is defined as the maximum difference (regardless of the direction) when a rotation stage rotates twice of full turns of CW and CCW direction. The difference is calculated by comparing actual positioning in each angle from the first and second same directional rotation, and a bigger difference from CW and CCW rotations is defined as the maximum difference and same as the angular repeatability. The definition of angular repeatability of tangent-bar lead mechanism motorized rotation stage is same as motorized swivel stage. 임의의위치를기준점으로정하고기준점에서한방향으로일정간격으로순차적으로위치결정을실시하고, 각각의위치결정지점에서의측정값 ( 기준점에서실제로이동한위치 ) 과지령값 ( 지령한실제로이동해야하는위치 ) 과의차이를웜휠의 1 치 ( 웜축 1 회전 ) 분의범위에서측정하고그최대차이 ( 좌측그림의 ΔL) 를피치오차라고합니다. Speed reduction ratio in the worm wheel used for our rotation stage is basically 1 / 180. This means that the gear has 180 teeth at the circumference.

An indicator is placed into contact in the vicinity of external periphery of the table, and a measurement is made at 36 points for every 10. Maximum error ( peak to peak ) is obtained. This value is the sum of deviations resulting from surface runout errors and that derive from finished table surface irregularities.

The inner diameter as a reference is provided in the main shaft. During final assembly, displacement of this inner diameter is measured with an indicator. This value is the sum of roundness deviations of the inner diameter and eccentricity, and we define this value as eccentricity (only for Mont-Blanc series). The eccentricity of tangent-bar lead mechanism rotation stage is measured in full stroke angular range. 시스템제품 Products 수동정밀스테이지Manual Stage 자동정밀스테이지Motorized Stage 산 얼라인먼트스테이지X 진공스테이지Vacuum Stage 검 제품문의 TEL :+81-44-981-2131 / FAX :+81-44-981-2181 E-mail sales@kohzu.co.jp URL http://www.kohzu.co.jp P-009
