GB/T 4096---2001
This standard is equivalent to ISO2538:1998 "Product Geometric Specification (GPS) Angle and Slope Series for Prisms", which is a revision of GB/T4096-1983 "Angle and Slope Series for Prisms". The technical content is consistent with the international standard. Considering that the scope of application of the standard is prisms for general purposes, the prisms for specific purposes in the main text of ISO2538 are given as appendices to the standard. The main modifications of this standard to GB/T4096-1983 are as follows: the terms and definitions of wedges, guide prisms, etc. and the corresponding diagrams are added; the numerical tables are rearranged;
prisms for specific purposes are listed as appendices to the standard. This standard replaces GB/T4096-1983 from the date of implementation. Appendix A of this standard is the appendix to the standard. This standard is proposed by the China Machinery Industry Federation. This standard is under the jurisdiction of the National Technical Committee for Standardization of Product Dimensions and Geometric Specifications. The drafting units of this standard are: China Academy of Mechanical Science, China National Institute of Metrology, China First Tractor Group Co., Ltd., Tianjin University, and Changan Automobile Group Co., Ltd.
The main drafters of this standard are: Li Xiaopei, Zhang Heng, Zhang Yunli, Wang Zhong, Yi Shouyun, and Chen Ge. 276

ISOForeword
ISO (International Organization for Standardization) is a worldwide joint organization composed of national standard bodies (ISO member bodies). The formulation of international standards is usually completed by ISO's technical committees. If each member body is interested in a project established by a technical committee, it has the right to send personnel to participate in the work of the project. International organizations (official or unofficial) that maintain contact with ISO may also participate in the relevant work. ISO maintains a close cooperative relationship with the International Electrotechnical Commission (IEC) engaged in electrical standardization. The draft international standard adopted by the technical committee is submitted to the member bodies for voting, and it must obtain the consent of at least 75% of the member bodies before it can be published as an international standard.
International Standard ISO 2538 was drafted by ISO/TC213\Product Dimensions and Geometric Specifications and Inspection\Technical Committee. This second edition replaces the first edition (ISO 2538:1974). Some data in the tables have been amended in due course, but there are no technical changes. Annexes A and B of this international standard are informative appendices. 277

This standard specifies the series of angles and slopes on prisms for general purposes. The angle series ranges from 120° to 0°30°, and the slope series ranges from 1:10 to 1:500.
This standard is applicable to general mechanical engineering.
2 Definitions
This standard adopts the following definitions.
2.1 Prism
A geometric body defined by two intersecting planes and a certain size (see Figure 1). Note: The two intersecting planes are called "prism faces" and are called "prism matching faces" when there are matching requirements. The intersection of the two prism faces is called "edge". 2.2 Multiple prism
A geometric body defined by several pairs of intersecting planes and a certain size (see Figure 2) Note:
1 A double prism is defined by two pairs of intersecting planes and a certain size (see Figure 2). 2 When each pair of planes intersects at a point, the multiple prism is a pyramid (see Figure 3). 2.3 wedge
a prism with a small angle.
2.4 slideprism
vee-block
dovetail
a specific prism with a large angle (see Figures 4 and 5). Note: These specific prisms are often used in guideways of machine tools. 2.5 prism angle (β)
the angle between two intersecting prism faces (see Figure 1). Note: The angle between the mating faces of a prism is called the “mating angle of the prism”. 2.6 center plane of prism (Em)the plane through the edge that bisects the prism angle β (see Figure 7). 2.7 height of prism
the height measured on a specified section parallel to the edge and perpendicular to one of the prism faces (such as H and h in Figure 6). 2.8 thickness of prism Approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on September 15, 2001 278
Implementation on April 1, 2002
GB/T4096—2001
The thickness measured on a specified section parallel to the edge and perpendicular to the prism center plane EM (such as T and t in Figure 7). 2.9 prism slope (S) The ratio of the difference between the prism heights H and h of two specified sections to the distance L between the two sections (see Figure 6). H—h
The relationship between the prism slope S and the prism angle β is
S - tanβ = 1 : cotp
2.10 prism ratio (C,) The ratio of the difference between the prism thicknesses T and t of two specified sections to the distance L between the two sections (see Figure 7). C,T
The relationship between the prism ratio C, and the prism angle β is C, 2tan
3 series
The angle and slope series of general-purpose prisms are specified in Table 1. When selecting prism angles, series 1 should be preferred, followed by series 2. In order to facilitate the design, production and control of prisms, Table 2 gives the estimated values ​​of prism ratios, slopes and angles corresponding to prism angles and prism slopes, and the number of significant digits can be determined as needed.
