INTRODUCTION

1 SYNTHESIS AND ANALYSIS OF LEVER MECHANISM

1.1 Initial data

1.2 Construction of Provisions Plans

1.3 Structural Analysis

1.4 Kinematic analysis by plan method

1.4.1 Construction of speed plan

To determine the direction of the 4, the speed plan segment cd is set to point D, the point C is fixed (Figure 4, c), so the 4 is also directed counterclockwise.

1.4.2 Build Acceleration Plan

1.7 Power calculation

1.7.1 Determination of inertial factors

1.7.2 Power calculation of Assur II2 group (4, 5)

1.7.3 Power calculation of Assur II1 group (2, 3)

1.7.4 Power calculation of I class mechanism

2 FLYWHEEL CALCULATION

2.1 Determination of the listed factors

2.2 Plotting

2.3 Determination of flywheel inertia moment and its dimensions

3 SYNTHESIS AND ANALYSIS OF CAM MECHANISM

3.1 Pusher motion diagrams

3.2 Determining the main dimensions of the mechanism

Summary

Calculation of the optimal cutting mode: a course project for cutting materials. - Chelyabinsk: SUSU, 2016. - 19 s., 3 ill., 4 tables, bibliography of literature - 3 items .

As a result of the course work, calculations of rational cutting modes were made using two methods: analytical and tabular. The cutter material and geometry, type, and dimensions are selected. The working drawing of the cutter was made, the cutting modes calculated in two ways were compared.
